Fault Name: Op Error Fault
Description: A SCANport device requests a Read or Write of data type not supported. This will also occur if:

1. [Motor Type] is set to "Sync PM" and [Stop Mode Used] is set to "DC Brake".
or
2. [Motor Type] is set to "Sync Reluc" or "Sync PM" and [Speed Control] is set to "Slip
