Y-axis

3rd axis
Z-axis

4th axis
A-axisThis manual basically explains only the X-axis.

Description of safety
This product must be handled correctly.
Handling the product incorrectly may cause unexpected accidents resulting in personal injuries ordamage to your properties.
Many of those accidents can be avoided if you have advance information on dangerous situations.
This manual provides precautions where dangerous situations are predicted. The manual provides thefollowing alert marking and messages for this purpose:
 WARNING

This indicates a hazardous situation that could result in death or serious
personal injury if you do not perform the procedure correctly.

 CAUTION

This indicates a potentially hazardous situation that could result in personal
injury or physical damage if you do not perform the procedure correctly.

Before use■ This product is not designed for use in the equipment related to nuclear power, aerospace equipment,
vehicles, marine vessels, medical equipment directly in touch with human body, equipment
anticipated to give a serious impact to properties, and other equipment required to provide highreliability.
■ Take failsafe measures so that the whole system operates safely even if the input power causes anerror, a signal line is disconnected, or the main unit fails.
■ This product is equipped with a LIMIT ( overtravel) signal and an FSSTOP signal to prevent
mechanical damage.
The default values of these signals are set to ACTIVE OFF ( B contact ). Accordingly, even in asystem configuration in which the FSSTOP and LIMIT signals are not used, pulses are not output
unless NORMAL ON ( GND connection) is enabled.
■ Be sure to use this product within the scope of the specifications described in this instruction manualin accordance with the specification method described therein.
■ Set up the product before operating it.
Please refer to the Section 3, "Setting."■ Please refer to separate manual "AL-Ⅱ series device driver manual for Windows" also when you
handle this product.

・ The shift of board controller C-VX870 series ( Device-function) for PCI made of our company and the AL- Ⅱ series( Device-function and Unit-function) is easy depending on the device driver function for Windows.
● The status of four axis batch reading and the command of four axis batch execution by the Unit-function is possible.
This Unit-function can perform a unit and USB interface by one function execution from an application.
By this,・ The time crunch can be done compared with accessed Device-function of each axis and I/O-function ofeach I/O port.
・ The Unit-function ( writing) suppresses the difference at time until it instructs time each axis and each I/O output
signal.
・ The Unit-function can reduce the load of the application.
・ It supports the Device-function, and can use the Device-function.
The application of device function can be used for UC-766.

Operation not anticipated may cause damage of the machine and the product.

 QAUTION

Avoid the connection of method through the hub for stability of the USB series product.

Operation not anticipated may cause damage of the machine and the product.

 QAUTION

To prevent the malfunction by the noise, the USB communications cable recommends
recommended cable.

Reference● Recommended USB cable
KU-AM510 ( L ＝ 1 m) :Made of Sanwa Supply
KU-AM530 ( L ＝ 3 m) :Made of Sanwa Supply(1) Wiring distance of USB communication
The wiring distance of the USB communications cable is recommendation 1 m 〜 3 m.
Use it within the range of 5 m( maximum) .
Moreover, the wiring distance of Extend I/O unit is from each USB unit to 1 m or less.

UNIT(2) Connection of USB communication● Locks with a cable clamp so that a USB cable does not come off by external force.
Twist lock
After the USB cable is connectedwith the J1 connector, the cable ispassed through the cable clamping.
And , the cable is prevented fromcoming off by twist lock.

● In the USB series, the number that can be connected with one personal computer is up to two.
Generally, USB is a standard with which two or more equipment can be connected with the hub.
However, avoid the use of the hub because of reliability when using it in the control system.
Examine our company AL-Ⅱ series when controlled number of axes and I/O number are insufficient.

５． Maintenance
Incorrect handling may lead to an electric shock.

 QAUTION

Inspection and maintenance need to be conducted by an expert engineer only.
Before inspecting and maintaining this product, turn off the power.

An electric shock, injuries, and fire may be caused.

 QAUTION

Do not make repair and modification such as product disassembly and parts
replacement.

5-1. Maintenance and inspection(1) Cleaning method
To use the product in a favorable condition, conduct cyclic cleaning as follows.
・ During the cleaning of the connector terminal plating part, wipe it with a dry, soft cloth.
・ If stain is not removed by the dry wiping, soak a cloth in a solution in which neutral detergent is diluted,
wring it out, and wipe off the stain with it.
・ Do not use a high-volatile solvent such as benzene and thinner, and a wipe.
This may deteriorate gold plating by transformation and oxidation.

(2) Inspection method
To use the product in a favorable condition, conduct periodic inspection.
Usually conduct the inspection every six months or every year.
To use the product in an extremely hot and humid or dusty environment, shorten the inspection interval.
