Request reference mirrored
= 25 hex
Axis mirrored = 02 hex
Format = 06 hex
1. value = 1355 dec
2. value = 0 dec
...
8. value = 0 dec
This response belongs to the request with request reference 25.
01 hex → Read request positive, values available starting from 1st value
The values correspond to the values from the request.
06 hex → Parameter values are in the unsigned16 format.
08 hex → 8 parameter values are available.
A fault is only entered in value 1 of the fault buffer for drive 2.
Special requirements for this example:
