Information about the parameter request:
● Request reference:
The value is selected at random from the valid value range. The request reference
establishes the relationship between request and response.
● Request ID:
01 hex → This identifier is required for a read request.
● Axis:
02 hex → Drive 2, fault buffer with drive- and device-specific faults
● Number of parameters:
01 hex → One parameter is read.
● Attribute:
10 hex → The parameter values are read.
● Number of elements:
08 hex → The actual fault incident with eight faults is to be read.
● 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.
