Subfault: 14.18
Description: Permanent low level in data line – critical
Response: Encoder 2 – latest critical fault
Cause Measure
Permanent low level of data signal detected. – Check wiring.
– Check encoder.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.19
Description: Permanent low level in data line
Response: Encoder 2 – latest fault
Cause Measure
Permanent low level of data signal detected. – Check wiring.
– Check encoder.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.20
Description: SSI error bit – critical
Response: Encoder 2 – latest critical fault
Cause Measure
Error bit set in SSI protocol. – Check startup parameters.
– Check the settings at the SSI encoder (error bit).
– Check wiring.
– Check interference source (light beam interrupted, reflector,
data cable, etc.).
– Replace encoder.
Note: In the "emergency mode" manual mode, you can move
the drive even with a fault in the external position encoder.
Subfault: 14.21
Description: SSI error bit
Response: Encoder 2 – latest fault
Cause Measure
Error bit set in SSI protocol. – Check startup parameters.
– Check the settings at the SSI encoder (error bit).
– Check wiring.
– Check interference source (light beam interrupted, reflector,
data cable, etc.).
– Replace encoder.
Note: In the "emergency mode" manual mode, you can move
the drive even with a fault in the external position encoder.
Subfault: 14.22
Description: Internal fault – critical
Response: Encoder 2 – latest critical fault
Cause Measure
Encoder signaled internal fault – 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.
