8.6.6 Fault 8 Speed monitoring
Subfault: 8.1
Description: Speed monitoring – motor mode
Response: Output stage inhibit
Cause Measure
Speed controller operates at setting limit (mecha-
nical overload or phase failure in supply system
or motor). Increase the delay time set for speed monitoring,
or reduce the load.
Encoder not connected correctly. Check encoder connection and direction of rota-
tion. If necessary, increase current limiting or re-
duce acceleration values.
Encoder has incorrect direction of rotation. – Check encoder connection and direction of ro-
tation. If necessary, increase current limiting or
reduce acceleration values.
– Check motor lead and motor, check line
phases.
Subfault: 8.2
Description: Speed monitoring – generator mode
Response: Output stage inhibit
Cause Measure
Speed controller operates at setting limit (mecha-
nical overload or phase failure in supply system
or motor). Increase the delay time set for speed monitoring,
or reduce the regenerative load.
Encoder not connected correctly. Check encoder connection and direction of rota-
tion. If necessary, increase current limiting or re-
duce deceleration values.
Encoder has incorrect direction of rotation. – Check encoder connection and direction of ro-
tation. If necessary, increase current limiting or
reduce deceleration values.
– Check motor cable and motor. Check line
phases.
Subfault: 8.3
Description: Maximum speed at motor shaft
Response: Output stage inhibit
Cause Measure
Actual speed exceeded "Maximum speed at mo-
tor shaft" limit value (index 8360.9 / 8361.9). This
limit value is set at startup matching motor and
gear unit. Reduce the maximum rotational speed.
