Subfault: 14.7
Description: Signal level too high
Response: Encoder 2 – 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: 14.8
Description: Signal level monitoring
Response: Encoder 2 – latest critical fault
Cause Measure
Vector below permitted limit during signal level monitoring Check the encoder 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: 14.9
Description: Quadrant check
Response: Encoder 2 – latest critical fault
Cause Measure
Error while checking quadrants (sine encoder) Switch the device off and on again.
– Check wiring.
– Check interference source (e.g. from EMC).
– Check 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.
Subfault: 14.10
Description: Position tolerance range monitoring
Response: Encoder 2 – latest critical fault
Cause Measure
Position outside tolerance range – Check startup parameters.
– Check wiring.
– Check interference source (light beam interrupted, reflector,
data cable, etc.).
– Replace encoder.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.11
Description: Data timeout
Response: Encoder 2 – latest critical fault
Cause Measure
Encoder process data timeout – Check interference source (e.g. from EMC).
– Check startup parameters.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.12
Description: Emergency
Response: Encoder 2 – latest critical fault
Cause Measure
Encoder signaled emergency – Check interference source (e.g. from EMC).
– Check startup parameters.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
