Write Request (Read Parameter Value)
Positive Read Response to Read Request
Negative Response to PROFIdrive Read Request
0x78 PZD map failure Parameter cannot be mapped to PZD (size mismatch or non-existent).
0x79 PZD memory failure Parameter cannot be mapped to PZD (out of memory).
0x7A Multiple PZD map Parameter cannot be mapped to PZD (multiple PZD write).
0x8C Set torque mode error Cannot change mode to TORQUE (frequency is used).
0x90 Illegal Request ID The request ID of the response is illegal.
