How to use EX-EC module?
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.
| RPDO1 | The command from AC Driver | 01: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 |
| RPDO2 | AC Driver’s target frequency | -10000~10000 (-10000 for -100% 10000 for 100%) |
| TPDO1 | AC Driver state | 01: Running forward 02: Running reverse 03: Standby 04: Fault 05: Under-voltage 06: Direction switching |
| TPDO2 | Running frequency(Hz) | 0.01Hz |
| TPDO3 | Setting frequency(Hz) | 0.01Hz |
| TPDO4 | Bus voltage(V) | 0.1V |
| TPDO5 | Output voltage(V) | 1V |
| TPDO6 | Bus current(A) | 0.1A |
| TPDO7 | Output power(kW) | 0.1% |
| TPDO8 | Output torque(%) | 0.1% |
| TPDO9 | DI Input state | |
| TPDO10 | DO 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 in PLC 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.
