configuring GS1-21P0 to p3-550

configuring GS1-21P0 to p3-550

Hi , I am trying to operate GS1-21P0 using RS-485 serial port in P3-550. I am using modbus RTU protocal to communicate. However, my GS1-21P0 is showing an error code cE01.
Can any one help on this.

RE: configuring GS1-21P0 to p3-550

All those model numbers are just Greek to me. What are they, functionally?

What's the error code mean?

RE: configuring GS1-21P0 to p3-550

To clear up any confusion, they are a VFD and PAC from AutomationDirect, respectively.

RTFM. It says:

Quote (GS1 Manual)

Communications Warning:
Illegal command code - The
command code received in the
command message is not
available for the AC drive.

In other words, you're sending a command from the PAC that the drive does not recognize. Rewrite the command you're sending so it is valid for the drive.
