Chapter 1 Introduction

1-2. UNR-G series system
The UNR-G series nutrunner is an electric nutrunner. The UNR-G series nut runner is a tool to tighten bolts or nuts
automatically.
The UNR-G series system is the latest clamping system developed with the aim of making UNR-F series systems evensimpler and more flexible. The function of the main unit is incorporated in the conventional spindle unit, and the multi-spindle
system control and external communication functions are enhanced to realize a tightening system that flexibly responds to theever-evolving futuristic production facilities.
For the UNR-G series, a servomotor is used as the drive source, and a torque transducer (torque sensor) can be used todetect the torque and tighten it to the set torque.

○ Reduced startup time
No complicated PLC ladders are required for controlling multi-spindle systems.
The tightening procedure requires no expertise, as it can be incorporated by very easy-to-understand parameter settings.
Contributes to work improvement on the site.

○ Ease of setting change
Tightening parameters, tightening workpieces, and various other settings can be easily executed with the dedicatedsoftware UNR-G series user console.

○ Diversification of external control interfaces
Various fieldbuses can be supported by mounting an Extension unit. All communication of control signals between theexternal device and the system can be controlled.

○ CF card-based tightening data-saving
By installing an Extension unit, you can save the tightening result and the tightening wave form to Compact Flash(CF). The number of data that can be saved varies depending on the number of connected spindles, the tightening
method, etc., but in 8GB, approximately 1,800,000 data for 1-spindle systems, approximately 900,000 data for 2spindle systems, approximately 600,000 data for 4-spindle systems, approximately 400,000 data for 8-spindle
systems, approximately 200,000 data for 16-spindle systems, and approximately 100,000 data for 32-spindle systems
can be saved.

○ High-speed communication with the host system
Ethernet communication is used to communicate with PC, which reduces data communication times. Also, thededicated communication method is used for communication between units, enabling a communication rate approximately
250 times faster than that of UNR-F series.

○ Power supply and I/O for a variety of safety measures
Since it is equipped with an independent emergency stop signal, it responds to interruption of tightening operation.
In addition, since the unit is operated with DC 24V control power supply, the status of the system can be communicatedto the host system even if the drive power supply is cut off during an emergency stop.

○ Multi-functionalization of the unit
By incorporating the function of the main unit into the function of the conventional spindle unit, it is possible to copewith the fieldbus specification with a single unit, realizing a drastic size reduction of the installation area.

If an error occurs in the system due to a system check, connection check, overload check, etc., an alarm
signal is output. At that time, STATUS LED of the unit lights in red and the alarm number and sub-code aredisplayed on the unit's display.

(4) Tool type check function
When the power is turned on or when the tool is replaced, the tool model set in the unit is checked against
the model of the connected tool. If the tool model is different, an alarm signal A.03-02 "Tool type error" will
occur.

(5) Self-check function
When the control power is turned on, ZERO voltage and CAL voltage that are used as the reference fortightening are obtained. In addition, perform a self-check to compare the reference value at power-on with themeasured value before the start of tightening operation by acquiring the value of ZERO voltage and CAL voltage ofthe torque transducer before the start of tightening operation. (Self-check is not executed for reverse operation.)
In addition, tightening can be started without performing self-check according to the following settings.
PLC I/O INPUT "Auto Z/C CHECK OFF":"ON"(6) Tightening torque waveform display function
The waveform of tightening torque can be displayed from the end of tightening to the point prior to 1980deg orfrom the start of tightening to 40 seconds on the dedicated software UNR-G series user console.

(7) Error history function
If an error occurs in the unit and an alarm is issued, up to 500 alarms are saved in the unit and 20
alarms are saved in the tooling ID.

PAGE 1-4

Chapter 1 Introduction(8) Waveform history function
The module stores 100 pieces of 2 types (OK/NG) of tightening data. A UNR-G series user console isrequired to read the waveform history.
・Save format: Torque-angle (540deg)

・Saved data (waveform history) : Up to 100 from the latest results※The saved data (wave history) is erased when the control power supply of the unit is turned OFF.
・Saved data (NG waveform history): Spindle-determined "NOK", "ALARM", and “STOP” for 100 cases among the mostrecent data.

(9) Tightening Result History Function
Saves the tightening results up to 12000 data points before the latest results in the unit. The UNR-G series user
console is required to read the tightening result history.
MASTER spindle saves the tightening result of the whole main-system separately from the result of each spindle.
The number of items that can be saved for the whole main system depends on the number of configuration axes.

The UNR-G series nutrunner system controls all units collectively by setting one unit I/0(PLC) control. Units that
communicate directly with PC or fieldbus are called MASTER spindle. Units that communicate with PC or fieldbus
through inter-spindle communication via MASTER spindle are called SLAVE spindle.
※MASTER and SLAVE spindles of the UNR-G series user console (PC) and I/O (PLC control are set using the special function
SW1 switch on the front of the unit. Refer to PAGE 2-18 "Special function SW1 switching setting".

Limited value under continuous operation for long time (no limit in small number of times)[Precautions for drive power-on cycle]
・The power input circuit of the module is a capacitor input type. Therefore, there is anincorporated circuit that charges through a resistor by suppressing the inrush current at
power-on until the internal voltage reaches a certain reference.
・The inrush current suppression resistor has a mechanical life. When turning OFF and ON thedrive power at a fixed cycle, consider turning on/off the drive power with reference to the"Allowable number of times the drive power is turned on/off" table above.

Chapter 1 Introduction

・Pay attention to static electricity because the unit contains many electronic components.
Excessive static electricity may be generated in a dry place. Before touching the operation
switches on the front panel, touch a grounded metal object to discharge static electricity from thehuman body.

1-6-4. Duty calculation method
Duty is the ratio of the tool stop time to the tightening time.
In the UNR-G series Nutrunner system, the duty is calculated as shown below.
Duty (%) = Tightening time ÷ (Tightening time + Idle time) × 100
1 cycle time specification depends on each tool, but should normally be less than 60%. If operation iscontinued with the duty factor exceeding 60%, an alarm A.08-10 "Overload error" may occur. Contact us for
information on the time specifications for the 1 cycle.

2-2-6. Explanation of I/O signals[Input Signal]

・This chapter describes the input-signal usage of the standard I/O. For the input
signals used by the fieldbus or extension I/O, see PAGE4-4 "Input Signal
Description".

OPERATION PREPARATION: Preparing for operation
Operation is possible with ON, and operation is stopped with OFF.
RESET: Resetting
When RESET signal is turned "ON", the output signal of the tightening result judgment disappears.
When RESET is "ON", the tightening operation cannot be started. In addition, if RESET is turned "ON" during
the tightening operation, the tightening operation will stop, but the tightening result data just before the stop will
be held.
REVERSE: Tool Reverse
In the main system, the spindle number selected by WORK SELECT BIT0～4 signal is used as the target, and the tool
rotates in the opposite direction at the set rotation speed. However, if REVERSE is started under the following conditions,the reverse-rotation will not be started.

◆ During tightening operation (when WORKING is "ON")◆ ALARM signal "ON" or RESET signal "ON"◆ When REVERSE signal is "ON" previously◆ Unit is in BYPASS status◆ Unit is in STOP status◆ CAL is being checked by CAL switch.

PAGE 2-9

Chapter 2 Installation

START: Tightening starts
At the level-input ("OFF"→"ON") of START signal, the work number and SELF CHECK DISABLE signal selected by thesignals from WORK SELECT BIT 0 to 4 are read, and the tightening operation starts. From the start of tightening to the endof tightening, WORKING of the unit is turned "ON". If START is turned "OFF" during the tightening operation, the tightening
operation will be stopped. Tightening cannot be started if START is turned on under the following conditions.

◆

ALARM signal "ON" or RESET signal "ON"◆When REVERSE "ON"◆◆◆G-Unit is in BYPASS status (setting value editing, communication, etc.)
G-Unit is in STOP status
CAL is being checked by CAL switch.

BYPASS: Spindle Disabled
When BYPASS signal is set to "ON", the unit of the selected spindle No. is in BYPASS status, and the output
signal of the result-attached judgment or LED indication other than BYPASS disappears. In addition, if BYPASS
occurs during the tightening operation, the tightening operation will stop, but the tightening result data immediately
before the stop will be held.
AUTO Z/C CHECK OFF: Torque Transducer Self Check disabled
By setting AUTO Z/C CHECK OFF signal to "OFF", all the units connected will perform Z/Cchecking when START signal is inputted.
(Z/C check: Check ZERO and CAL voltages of the torque transducer) If Z/C check of the torque transducer is not
required, the tightening operation is started without executing the self-check by setting AUTO Z/C CHECK OFF
signal to "ON" when START signal is input. When AUTO Z/C CHECK OFF signal is "ON", ZERO voltage used
for tightening operation should be the value at the time of checking the latest. Checking ZERO voltage of thetorque transducer is performed at the following timing. Other than when tightening is started.

Wiring Procedure for Control Power Supply

1. Prepare the wires and bar terminals (ferrules) to use.
・Applicable wire... AWG 20～22 (0.3 ㎜ 2～0.5 ㎜ 2)

・Recommended bar terminal (ferrule)... Model: AI 0,5-6 WH (Phoenix Contact)

2. Strip the wire insulation, following the below dimensions.

3. Crimp with a crimping tool. After crimping, cut the wire end at a point as long as the ferrule
length or about 0.5 mm.
・Recommended Crimping Tool... Model: CRIMPFOX6 (Phoenix Contact)

4. Loosen the screw of the insertion port of the connector and insert the ferrule into the insertion port.
Insert one ferrule into one slot of the connector.

5. Tighten the screws of the connector's insertion slot and connect the cable to CONTROL POWER connector on the
middle left of the unit.
・Be sure to ground the power supply.
・Select ferrules according to the wire size to be used. If the ferrule size is incorrect, a gap will becreated when crimping, making the wire easier to get wet.
・Wire the control power supply (DC DC24V) with the correct polarity. Failure to do so
may result in an electric shock or damage to the unit.

PAGE 3-4

Chapter 3 Wiring and Test
Operation

3-3. Wiring and Fixing Tools
3-3-1. How to fix the tool
Pay attention to the following points so that there is no mechanical contact when installing the tool.
・Cabling or incorrect mounting position (method)
Securely fix the tool to the tool mounting plate with the bolts. If the torque accuracy becomes
unstable and the torque cannot be detected normally, there is a risk of mechanical damage suchas bolt breakage.

<Correct mounting method>

Attach the nut runner to the mounting plate with bolts.
<Wrong mounting method>
Do not overtighten the nut runner body. It may damage the motoror reduction gear section.
Do not hang only the nut runner, but hang and use the nutrunnermounting plate with the nut runner installed correctly.

[Installation Precautions]・Strong torque is generated when tightening the tool, and equivalent force is applied
to the mounting part of the tool. Therefore, when installing the tool, mount the tool
using the screws specified for the specifications.
・The inside of the tool is composed of mechanical parts and electronic parts including
sensors. Do not subject it to strong vibrations or excessive force.
・For high-speed operation with a short cycle time, use a cylinder cushion or shock
absorber to fix the tool anvil and to prevent excessive vibration. Impact can damage
the tool.

PAGE 3-5

Chapter 3 Wiring and Test
Operation

3-3-2. Routing the Tool Cable

1. When installing multiple nutrunners, attach stickers, etc. todistinguish them so that the spindle number can be known.
2. Connect the power cable to the external cable from the spindle
unit with the same number.
3. When the nut runner moves, install and wire so that no stress
is applied to the cable.
4. Fix the cable so that no force is applied to the connector.
Be careful not to over-secure it to the nut runner body.

<Precaution for Cable Wiring>
For the moving parts of the nutrunner cable, flexible in-tube wiring or cable track wiring is recommended. In addition, pay attention
to the following points when wiring the cable bundle in order to prevent wire breakage.
・To reduce the self-weight of the cable and to avoid stress caused by bending it back, divide the cable into several
pieces and bind them in a large number of bundles.
・Even if the cable is not a moving part, the weight of the cable bundle will be applied. Be careful not to touch the cable directly at
the corners.

[Cable Connection Precautions]・Be sure to turn off the control power of the system before connecting the cabling. Connecting or
disconnecting the cable may cause the product to malfunction.
・For the power supply to the system, use a cable that meets the specifications.
・When fixing the cable, do not bend the connector part of various connecting
cables or apply stress due to its own weight.
・Keep the bending radius of the standard-tool cable as large as possible (more than theradius 110mm).

3-9-2. Check items at power-on
When the control power is turned on, the display contents shift as follows.
RUN condition

Unit spindle No.: 1

Control power entry

All lights for approximately 6 seconds

BYPASS condition
If "ALAr" is displayed at the top row of the display when the control power is turned on, eliminate the cause by referring
to PAGE 9-3 "Description/Cause and Remedy" and ensure safety before turning the control power ON again.
Also, check the following precautions when turning on the drive power.

[Precautions when turning on the drive power again]
・When turning on the drive power again, be sure to wait for 20 seconds after the drive power isturned OFF before ON. If there is no waiting time or if it is turned on again within a short time,
the following problems may occur.
・The circuit protector for circuit protection may be cut off because an abnormal current
flows in the primary power supply circuit without the inrush current prevention circuit.
・The unit's power supply circuit detects an error and automatically shuts off thecircuit. As a result, the power circuit does not work even if the drive power
supply is turned on again. (will remain OFF)・If the drive power cannot be turned on again, wait for at least 5 minutes after the drive
power is turned OFF before turning it ON.

CYCLE START: Cycle start
Repeated operation starts at the beginning of operation ("OFF"→"ON":100msec") of CYCLE START during START
signal inputting. Even if CYCLE START is turned "OFF" during the tightening operation, the tightening operation will not
be stopped.
However, when START is turned OFF, the tightening operation is stopped and judgment is made.
CYCLE COUNT CLEAR: Resetting the work cycle countWhen CYCLE COUNT CLEAR is turned "ON", the cycle count of the selected work number is erased. The work
number after clearing the cycle count is the start of the next tightening operation, and the work cycle count is the first.
Work cycle count method can be changed by UNR-G Console.
(The factory default setting is "Auto Count Up")CYCLE COUNT UP: Count up of the work cycle counter
When the cycle count method of the work is "signal input", setting CYCLE COUNT UP signal to "ON" will increment
the cycle count of the selected work number by one.
Each time CYCLE COUNT UP is turned "ON", the work cycle count is incremented by one.
・When "Auto count up" is set as the method of the work cycle count, thesequential judgments including "OK", "NOK", or "ALARM" (Excluding ALARM10-*)increase the cycle count by one time.
・When a sequence judgment other than the above is finished, the cycle count is not
updated, and the same cycle count as the previous one is output at the start of the next
sequence operation.

4-1-7. ID entry setting
ID data. (Model No.) can be input for MASTER of PC communication and I/O (PLC) control in the UNR-G series system.
RS232C-2 interface of the fieldbus or Extension-unit 2 can be selected as the input-destination. The extension RS232C
is set in the default setting.
(Simultaneous entry from RS232C-2 of fieldbus and Extension unit 2 is not possible)
By inputting ID data (model No.) to MASTER spindle prior to starting the tightening operation, the input data isadded to the tightening data, and it is outputted from the UNR-G series user console, the standard RS232C, thefieldbus, and the Extension RS232C-3 interface of the Extension unit 2.

ID data entry

Extension unit 2 (model: UEC-GCF)
ID data entry[Precautions for entering ID]
・ASCII allowed character is "0x20" ～ "0x7E". If a code out of range is used, the display may
be garbled.
・The maximum number of characters that can be printed is 32 (32bytes).
・If ID data is input continuously prior to starting the tightening operation, all the input data will
be used as ID data.
・ID data to be used is acquired when the tightening operation starts. Complete the datatransfer before the tightening operation is started.
・If ID data is input during tightening operation, the input data is not accepted.
・Even after the input ID data is output after the completion of tightening operation, thesame data is output unless ID data is re-input.
・If ID data is entered after the completion of the tightening operation, ID data will be overwritten.

PAGE 4-19

Chapter 4 Extension unit

When Extension RS232C is selected for the data input method and "STX/ETX is added" is set, ID data is erased
when a STX signal is received from RS232C-2. The input data is confirmed when ETX signal is received, and ID data
is re-input. For ID data to be output, the data without STX/ETX is used.

In addition to the selection from PLC, you can set ID and UNR-G series user console-datum selection as a way of
selecting the sequence number. "Select from PLC" is set as the default setting. To set the sequence selection method,
use the UNR-G user console " RS232C input format/data input setting".

In Select from entry ID, you can set a ASCII of up to five characters for each sequence number.
If the selected setting does not match ID data because no ID data is input or the data has already been cleared,
set PLC IO input signal " ALARM " to " at startup of PLC IO input signal " START(REVERSE)".
When "Select from input ID " is set, if the entered ID data and the selected setting do not coincide, ID data is not
updated. It is updated and retained as ID data only when they coincide.
When "Select from PLC or UNR-G series User Console" is set, the entered ID will be updated andretained.
To clear ID data, set PLC IO input signal "Clear ID data" to "ON". For ID data input by PLC networking, clear ID data to
be sent from PLC by PLC in advance, and then set PLC IO input signal "ID Data Clear" to "ON".

・When inserting or removing a memory card, be sure to turn OFF the control power of the module.
・Note that data saved on the memory card may be deleted under the following conditions.
◆When the user mishandles the memory card◆• When the memory card is used or stored in an environment where static electricity or electric noiseis present◆When the memory card is not used for a long time・The memory card has a lifetime. If the machine is used for a long period of time (about six months
or more) or is not used for a long period of time, stored data cannot be read or written.
Back up the required data to a PC on a regular basis. If you are unable to read or write to
the data, replace the data with a new one.
・For stable operation, it is recommended to delete the data after backing up the data in the memory
card and use it with as much free space as possible.

4-3-1. Saving Memory Cards

1. With the unit not turned on, insert the memory card into the memory card slot (CF CARD) of
Extension unit 2, and then turn on the power.
・If the control power supply of the module is turned ON while a memory card is installedin the slot, it may take longer than usual for the module to operate because a folder forsaving files is created on the memory card.

・Insert the memory card vertically and slowly with the surface facing to the left. If thecard is reversed, it cannot be inserted, but if you try to force it in, it may cause damage
to the unit or the card.

2. After completion of the tightening operation with the memory card loaded, the data is saved.

・Do not pull the card out of the slot or turn OFF the control power of the unit
while the memory card is being saved.
The saved data or memory card may be damaged.
・Note that if the tightening cycle is very short (1 second or less), the previous
data may not be saved normally.

3. CF ACCESS LED lights up in green when data is stored on the memory card. CF ACCESS LED also lights up
in red if the memory card cannot be saved.

4-3-2. Data storage flow
The tightening result and the tightening waveform are saved in the memory card every time the tightening
operation is completed. The tightening data can be saved in TSV format for each date and displayed in Microsoft®
Excel ®. The tightening waveform stores the torque-angle (180deg) spindle waveforms as an extension dedicatedto the UNR-G series user console. The tightening waveform displayed in the "Waveform Monitor" of the UNR-G
series user console can be saved in TSV format.
For waveform display, refer to "Waveform Monitor" in the UNR-G series User Console Operation Manual.
●Tightening result
The tightening result is automatically saved in the "RESULT" folder to be created.
Folders for the calendar year and month of saved files, such as "201809", are automatically created in"RESULT", and folders are automatically created as "201810", "201811", and "201812" for each month orcalendar change.
Within the folder of "201809", the following files are saved at the end of the tightening operation.
RESULT\YYYYMM\YYYYMMDD.TSV (TSV format file)
Year and month Date
Saves the tightening result for one day for each file. When the creation date is updated, files areautomatically created in the same folder.

●Tightening waveform
Save the tightening waveform to the folder "CURVE" to be created automatically.
In "CURVE", a folder representing the calendar and month of a saved file such as "201809" isautomatically created, and a folder is automatically added with "201810", "201811" and "201812" for eachmonth or calendar change.
Within the "201809" folder, a folder representing the calendar and month and date of a saved file such as"20180901" is automatically created, and the folder is automatically added to "20180902", "20180903", and"20180904" for each time the date changes.
Within the 20180901 folder, a folder whose name is the time of the first saved tightening waveform is
automatically created, such as "123456 to ", "123616 to ".
40 waveform files are saved for each folder. When 40 waveforms are saved, the following folders and files
are automatically created in the "20180901" folder. In addition to the waveform file, a index.txt file for storing
the number of saved items is created in the "CURVE" folder.
・Do not change the content of index.txt file. Otherwise, the waveform file cannot besaved normally.

The waveform file is saved in the folder of "123456 to" at the end of the tightening operation.
Saves waveform data of multiple spindles operated in the work setting as one waveform file.

D-No.100 CAL value[N・m]Sets the full-scale torque value of the connected tool. When connecting a socket or an offset gear thatapplies a load to the tool anvil, or when the results of the tightening result indication and the tightening torquetester differ from the workpiece characteristics, the tightening torque can be corrected by CAL setting.
CAL to be changed =Actual measured torque (test result)/Target torque × CAL

e.g. D-No.100[CAL]:294.2N・m

・When changing CAL, calculate the mean value as the actual measured torque from thetightening result data. (The number of samples of the tightening result data should be 20 times
as a guideline.)

D-No.101

Peak torque low limit [N•m]

D-No.102

Peak torque high limit [N•m]

Set the high and low limits of the tightening torque.
If the tightening torque exceeds the peak torque high limit or does not reach the peak torque low
limit, the spindle judgment is NOK.
D-No.103

Cutting Torque [N•m]

Set the target torque for tightening.
Valid only when D-No.000 [Tightening method] is "Torque method".
Example: When 10.0 is set, tightening is executed until the torque value becomes 10.0 [N·m].
[Precautions for tightening]
Avoid tightening more than the maximum instantaneous torque of the tool.
Also, use the tool so that the duty (the ratio of the tightening time to the stop time) is within thespecification even when the torque is below the nominal torque. For details on how to calculate
the duty, refer to PAGE 1-16 "How to calculate the duty".

8-2. Inspection items
This section describes the simple inspection method of the system.
8-2-1. Torque transducer
The torque transducer of the UNR-G series system stores the calibrated value at the time of manufacture in thepreamplifier, and compares and judges the calibrated value with the current value for each tightening. It is maintenancefree, but it can be confirmed by the following method.

● Inspection method using the display of the unit
1. Perform this operation with PLC I/O output-signal "READY" set to "ON" without starting by external control.
2. With RESET switch on the unit display pressed, confirm that the value shown at the top row of the display isnear "0".

3. Confirm that JUDGE LED lights in green at the same time as step 2.
4. Confirm that the torque value at the upper stage of the display is the full-scale torque value whilepressing CAL switch on the unit display.

5. Confirm that JUDGE LED lights in green at the same time as step 4. ZERO and CAL voltages can bechecked by the following methods.
1.

The [ ] and [ ] switches on the unit display indicate the real-time mode (see PAGE 5-8).

2.

Use the [▲] and [▼] switches on the unit display to switch D-No. display to "1" and display the torque/voltage display.
The displayed value is the present value of ZERO.

3.

Holding down CAL button displays CAL voltage value at the top row of the display.
