Error pulses in incremental encoders
0x8092
or
10.2
Cause Encoder monitoring has found error pulses.
Number of increments per encoder revolution is incorrectly entered.
Encoder defective: Does supply the specified number of pulses.
Faulty or missing zero mark.
Radiated interference on the encoder cable.
Incorrect number of pulses between two zero marks (monitored with a tolerance
of +/- 7 increments).
No zero mark has occurred. The machine data Increments per encoder revolution
is monitored with a tolerance of +/- 7 increments.
Effect See Page 11-3
The outputs are switched off.
The synchronization is deleted.
The start enable is deleted.
Rectifica-
tion
Correctly enter the number of increments/encoder revolution (parameterization
interface).
Check the encoder and encoder cable.
Keep to shielding and grounding regulations.
Monitoring can be temporarily suppressed under the owner’s responsibility by
parameterization in the parameterization interface.
