CHAPTER

1SAFETY INFORMATIONSAFETY PRECAUTION• Before installation, wait until the temperature inside the welding power source
becomes low.
The main circuit parts are very hot immediately after welding.
Touching them accidentally may cause burn injury.

1.2.2

Precautions for power supply and electric shock

To prevent electric shock or burn injury, ensure to follow the instructions below:• Do not touch the input and output terminals and the internal live electrical parts of thewelding power source.
• Before starting installation, make sure to cut the input power with the disconnect switch
in the box connected with the welding power source and wait three minutes or more.
The capacitors may be still charged even after the input power is cut. Make sure that
there is no charged voltage before starting the work.
• Wear dry insulating gloves for protection. Do not use damaged or wet gloves.
• Tighten all cable connections and insulate them.
• Do not use a cable with insufficient capacity, serious damage or cable without
grounding.
• Never touch the parts that are not included in instructions during the work.

*4: When using the welding power source WB-DPS, use "24 V power cable (K8116F00)".
*5: One of either LC5EL-STP-BL-1 or SBXQ0087-01M is included.

NOTE• The customer must prepare the communication cable to connect the Welbee Inverter andcustomer's communication equipment. ("3.3 Connection of Communication Cable")• When installing in the welding power source WB-DPS, "24 V power cable (K8116F00)" isalso required. Purchase "24 V power cable (K8116F00)" separately.
• When installing in the welding power source WB-F300P, "Extension Board Mounting Kit (K5976)" is also required. Purchase "Extension Board Mounting Kit (K-5976)" separately.

2.2 Updating the Welding Power Source Software
Welbee Fieldbus Connection Tool can be used for all Welbee Inverters developed and distributed by
OTC. However, you may be required to update the welding power source software depending on the
manufacture year and month of your Welbee Inverter. Contact your dealer for details.

NOTE• In the updating of the welding power source software, the internal memory must be
initialized once. We recommend the data should be backed up when welding conditions andinternal functions (Function) are registered and set.
• For the details of data backup, refer to "7.3 Data Backup (Utilization of data)" in Chapter 7of the Owner's Manual of the Welbee Inverter.

This section describes the installation of Welbee Fieldbus Connection Tool, unlocking of Fieldbus option,etc.

3.1 Installation of Welbee Fieldbus Connection Tool
The following describes how to apply the Fieldbus supporting option to your Welbee Inverter using
Welbee Fieldbus Connection Tool.

3.1.1

Installation of EtherNet/IP connection typeThis section describes the installation procedures of EtherNet/IP connection type.

NOTE• When installing in the welding power source WB-DPS, "24 V power cable (K8116F00)" isalso required. Since the 24 V power cable uses "24 V power cable (K8116F00)", theoperations in Step 10 change. Install "24 V power cable (K8116F00)" before the operationsin Step 1. Refer to the instruction manual of "24 V power cable (K8116F00)" for details.
• When using the welding power source WB-DPS in parallel operation, connect Welbee
Fieldbus Connection Tool to the welding power source WB-DPS (Master) side.
• When installing in the welding power source WB-F300P, "Extension Board Mounting Kit (K5976)" is also required. Since the communication unit stationary plate in "Extension Board
Mounting Kit (K-5976)" is used for the communication unit stationary plate, the operationsin Steps 5, 6, 7, 8, and 11 change. Refer to the instruction manual of "Extension Board
Mounting Kit (K-5976)" for details.

1. Turn off the power switch on the primary side and shut down the power supply to the Welbee
Inverter.

2. Remove the top panel of the Welbee Inverter.

Installation of PROFIBUS connection typeThis section explains the procedures for installing the PROFIBUS connection type.

1. Perform the operations same as those in Steps 1 to 3 and Steps 5 to 17 of "3.1.1 Installation of
EtherNet/IP connection type".

NOTE• The communication unit described in Steps 9, 11, and 17 of "3.1.1 Installation of EtherNet/
IP connection type" is the communication unit of EtherNet/IP connection type. Its shape isslightly different from the communication unit used for the PROFIBUS connection type.
• When installing in the welding power source WB-DPS, "24 V power cable (K8116F00)" isalso required. Since the 24 V power cable uses "24 V power cable (K8116F00)", theoperations in Step 10 change.

3.2 Unlocking Fieldbus Option
To use the Fieldbus supporting option, unlocking the Fieldbus option is necessary. This section describes
the procedures to unlock the Fieldbus option.

NOTE• The unlocking procedure includes the operations to reset the welding conditions registered
to the memory and the settings of internal functions of the welding power source to theinitial values (as shown in Step 8 below). If you want to use the welding conditions registered
to the memory and the settings of internal functions, backup those data on an USB memoryin advance. For details of backup and importing of the backup data, refer to "7.3 Data
Backup (Utilization of data)" in Chapter 7 of the Welbee Inverter Owner's Manual.

TIPS• Fieldbus special functions are added, accompanied to the unlocking of Fieldbus option.
Refer to "3.5 Fieldbus Special Functions" for the details of the Fieldbus special functions.

1. Turn off the power of the Welbee Inverter.
2. Insert the USB memory for unlocking the Fieldbus option to the USB connector on the operation
panel of the Welbee Inverter.

3. While pressing the LOAD key, the SAVE key, and the ENTER key at the same time, turn on the powerof the Welbee Inverter.
● Hold the LOAD key, the SAVE key, and the ENTER key pressed without releasing them immediately.

The node address of the Welbee Inverter in DeviceNet communication (node address of thecommunication unit) is set to "1" and the communication speed is set to "500kbps".
If necessary, change the Node address and communication speed by operating the configuration switchof the communication unit.

･ Before operating the configuration switch, be sure to turn off the power of the Welbee
Inverter and the communication equipment.
･ Never touch any internal board, etc. other than the configuration switch and thecommunication unit.

1. Turn off the power of the Welbee Inverter.
2. Remove the top panel of the Welbee Inverter.
3. Remove the hatch on top of the communication unit.

IP address setting (PROFINET connection type)

The IP address of the Welbee Inverter in PROFINET communication (the IP address of thecommunication unit) is set to "192.168.0.2".
The IP address can be changed by using “HMS IPconfig”(an IP address setting tool), if necessary.
The installer of “HMS IPconfig” is obtained from the following web site (URL).
URL (As of October 5, 2022):
https://www.anybus.com/technical-support/resources/downloads-and-documentation?ordercode=AB7078

NOTE• Use a Windows PC furnished with an Ethernet port in order to install "HMS IPconfig".

1. Perform the operations same as those steps of "4.2.1 Installation of IP address setting (EtherNet/

Confirm that the transmission cycle of watchdog is correct. Error code "E-920" isissued when the watchdog bit does not change for 1 second.

Watchdog is not returned.

Restart the Welbee Inverter and confirm that the indication on the digital meterschanges from "HE" "LLO" to "FLd" "bUS" and then normal indication. Also,
confirm that E-922 error code is not displayed immediately after that.
If "FLd" "bUS" is not displayed, set the Fieldbus setting of Function to "Use".
