Acknowl. upon N: NONE
F31905 (N, A) Encoder 1: Parameterization error
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE, OFF1)
SERVO: ENCODER (IASC / DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: ENCODER (IASC / DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: A parameter of encoder 1 was detected as being incorrect.
It is possible that the parameterized encoder type does not match the connected encoder.
The parameter involved can be determined as follows:
- determine the parameter number using the fault value (r0949).
- determine the parameter index (p0187).
Fault value (r0949, interpret decimal):
High word - low word = information - parameter number
Info = 0:
No information available.
Info = 1:
The component does not support HTL level (p0405.1 = 0) combined with track monitoring A/B <> -A/B (p0405.2 = 1).
Info = 2:
A code number for an identified encoder has been entered into p0400, however, no identification was carried out.
Please start a new encoder identification.
Info = 3:
A code number for an identified encoder has been entered into p0400, however, no identification was carried out.
Please select a listed encoder in p0400 with a code number < 10000.
