Communication
A.1 Communication
● Parameter number:
945 dec → p0945 (fault code) is read.
● Subindex:
0 dec → Reading starts at index 0.
Initiate parameter request.
If ZSW1.3 = "1" → Initiate parameter request
Evaluate the parameter response.
Parameter response
Response header
Parameter value
Information about the parameter response:
● Request reference mirrored:
This response belongs to the request with request reference 25.
● Response ID:
01 hex → Read request positive, values stored as of 1st value.
● Axis mirrored, number of parameters:
The values correspond to the values from the request.
● Format:
06 hex → Parameter values are in the unsigned16 format.
● Number of values:
08 hex → Eight parameter values are available.
● 1st value ... 8th value
A fault is only entered in value 1 of the fault buffer for drive 2.
