8.6.6 Fault 8 Speed monitoring
Subfault: 8.1
Description: Speed monitoring – motor mode
Response: Output stage inhibit
Speed controller operates at setting limit (mecha-
nical overload or phase failure in supply system
or motor).
Encoder not connected correctly.
Encoder has incorrect direction of rotation.
Subfault: 8.2
Description: Speed monitoring – generator mode
Response: Output stage inhibit
Speed controller operates at setting limit (mecha-
nical overload or phase failure in supply system
or motor).
Encoder not connected correctly.
Encoder has incorrect direction of rotation.
Subfault: 8.3
Description: Maximum speed at motor shaft
Response: Output stage inhibit
Actual speed exceeded "Maximum speed at mo-
tor shaft" limit value (index 8360.9 / 8361.9). This
limit value is set at startup matching the motor
and gear unit.

Measure
Increase the delay time set for speed monitoring,
or reduce the load.
Check the encoder connection and direction of
rotation. If necessary, increase the current limiting
or reduce the acceleration values.
– 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.
Measure
Increase the delay time set for speed monitoring,
or reduce the regenerative load.
Check the encoder connection and direction of
rotation. If necessary, increase the current limiting
or reduce the deceleration values.
– Check the encoder connection and direction of
rotation. If necessary, increase the current limiting
or reduce the deceleration values.
– Check motor cable and motor. Check the line
phases.
Measure
Reduce the maximum speed.
