Installation

Removing the side panel, then the two connectors should be connected to each other.

After connecting to the PLC, if the connection is successful, LED5 blinks rapidly; otherwise, LED5 blinks at a slow rate or the status remains unchanged.

Operation

 You can download the module's XML file here. VC EtherCAT xml

Then import it to PLC software. The following is the table for the PDO.

RPDO1The command from AC Driver01:Running forward
02:Running reverse
03:Positive turn point stop
04: Reverse the dots
05: Free stop
06: Slow down & stop
07: Reset the fault
RPDO2AC Driver’s target frequency

-10000~10000

(-10000 for -100% 10000 for 100%)

TPDO1AC Driver state01: Running forward
02: Running reverse
03: Standby
04: Fault
05: Under-voltage
06: Direction switching
TPDO2Running frequency(Hz)0.01Hz
TPDO3Setting frequency(Hz)0.01Hz
TPDO4Bus voltage(V)0.1V
TPDO5Output voltage(V)1V
TPDO6Bus current(A)0.1A
TPDO7Output power(kW)0.1%
TPDO8Output torque(%)0.1%
TPDO9DI Input state 
TPDO10DO Output state 

Here is a simple project, you can use it to check if EX-EX work normally. EX-EC.wcp2

Problem

1. If the LED light status is normal, but after writing the frequency or control word, the inverter's status did not change.

VC need to operate in EtherCAT mode, set F0.01 = 2 and F0.03 = 9.

2.  If the LED light status is normal, but all the values of TPDO are 0 or the value of bus voltage did not change.

This is due to the XML file not being written to the EEPROM. First, download VC EtherCAT xml

Then need to connect PC to EX-EC then open the EEPROM programmer, select VC_EC xml for programming, like the demostration below.
