Hello all,
I am using a Delta inverter, VFD40WL21A on Modbus with a PLC. We are using the minimum communication parameters like RUN/ STOP, Direction and Speed.
I havent yet received the Keypad from the supporting concern and I used a Delta MMI to communicate to the drive to set the Acc / Decc speed. The issue is I am unable to find the parameter for Action if communication fails. It is not mentioned anywhere in the technical writeup. But being a CE and UL approved component, I am very sure the same will be there. We cannot spare an output in PLC to detect communication failure and Put OFF the drive.
The issue arises only when a communication failure occurs when the drive is running.
Kindly comment...
