Hi all,
I am looking to find out where my problem is regarding this situation. To my knowledge I have all the correct settings, but when I remove the Modbus Connection from my VSD, the VSD does not show a Comms Fault, even though i set it to 'fault if comms loss'
any ideas?
My PowerFlex Settings are:
Start Source =5 Comms Port
Speed Ref = 5 Comms Port
Comms Data Rate = 4 (19.2 K, and is matched with my program configuration)
Node Address = 1 (Unique address)
Comms Format = 0 RTU 8 N -1
I also checked Parameter D012 which correctly shows the value of 55 confirming that the Control Source is Via Modbus Comms.
With my really basic program running,
I have also interogated d015, but I get a value of : 0000 without any activity, so its very hard to diagnose at the moment.
A little stuck, and some advice would be appreciated.
Ps: Wiring to VSD is done exactly as RS485 Protocol in Appendix C of the 4M manual.
