Error description: Velocity loop interrupted timeout
Diagnosis
Verify if encoder connection is
and that the encoder cable is too
not long (more than 20 meters)
Restart driver

Error description: Homing error
Diagnosis
1. Verify if homing velocity is too
high
2. Verify if homing mode is set
correctly
3. Verify if sensor signal edge is
consistent
1. Homing acceleration/
deceleration is set too low
2. Electronic gear ratio is low
which causes acceleration/
deceleration to be too low
Display:
"Er
920"
Error description: External encoder parameter initialization error
Diagnosis
Verify if Pr0.37 set value is out of
range
User manual of EL8-EC***F AC Servo
Solution
Replace encoder cable if necessary
Replace the drive with a new one
Solution
Please contact our technical
support
Solution
1. Set an optimal homing velocity
2. Make sure sensor signal edge is
consistent.
1. If electronic gear ratio cannot be
changed, please set a suitable
609A.
2. Increase electronic gear ratio
Solution
Modify Pr0.37 set value, please use
default value and see if the error
still persists.
