Cause
Remedy
A
Servomotor wiring incorrect or
disconnected
Check wiring and connectors at
servomotor.
B
Encoder wiring incorrect or disconnected
Check wiring and connectors at encoder.
C
Load greatly exceeds rated torque
Reduce load torque and inertia. Otherwise,
replace with larger capacity servomotor.
D
Incremental encoder power not supplied
from Servopack.
Use the Servopack power supply for the
encoder.
E
Circuit board (1PWB) defective
Replace Servopack.
