Subfault: 13.6
Description: Signal level too low
Response: Encoder 1 – latest critical fault
Cause Measure
Vector below permitted limit during signal level
monitoring. – Check the wiring.
– Check interference sources (e.g. from EMC).
– Check the encoder.
Note: In "emergency mode" manual mode, you
can move the drive using the motor encoder if the
external position encoder is faulty.
Subfault: 13.7
Description: Signal level too high
Response: Encoder 1 – latest critical fault
Cause Measure
Vector exceeds permitted limit during signal level
monitoring. Check the gear ratio of the resolver in use.
Note: In "emergency mode" manual mode, you
can move the drive using the motor encoder if the
external position encoder is faulty.
Subfault: 13.8
Description: Signal level monitoring
Response: Encoder 1 – latest critical fault
Cause Measure
Vector exceeds permitted limit during signal level
monitoring. Check the resolver mounting position.
Note: In "emergency mode" manual mode, you
can move the drive using the motor encoder if the
external position encoder is faulty.
Subfault: 13.9
Description: Quadrant check
Response: Encoder 1 – latest critical fault
Cause Measure
Error checking quadrants (sine encoder). – Switch the device off and on again.
– Check the wiring.
– Check interference sources (e.g. from EMC).
– Check the encoder. Replace if necessary.
Note: In "emergency mode" manual mode, you
can move the drive using the motor encoder if the
external position encoder is faulty.
