PLC vs Solid State Relay Drive Parameters

PLC vs Solid State Relay Drive Parameters

PLC vs Solid State Relay Drive Parameters

(OP)
Hi everyone,
I just got into this issue and I'll like some help:
I had a 7.5 HP motor driven by Solid State Relay and I replace the SSR with PLC. Now my question is that it should require to change parameters on the drive or the motors should run fine with same parameters (considering that we used same terminals at the drive for the same function)?
Thank you!

RE: PLC vs Solid State Relay Drive Parameters

If you need to change parameters in drive then you need some type of communcations interface to drive. The usual comm interfaces for drives are devicenet, rs485, profibus, or ethernet. If you do this comms interface then your wiring would change to only a control interface of enable and/or safe off, the rest would be done over the comms interface. The comms interface in the manual will explain how its done in the comms interface manual for that particular drive

The communication between the drive and PLC is made using the same com cable(shielded)that was used with the SSR (one end of cable at PLC & the other one at drive at same control circuit terminals). The parameters at drive we use to change them by using the digital operator at the front cover of the drive (manually.

Then you need some way to document the drive parameters either backed up with a manufacturers drive software or write down the non default parameters and put on your prints.

Thanks for the help. My equipment is working and there were no other adjustments required regarding the drive parameters.
