Solution
4. The gains are improper or
the stiffness level is too high.
Check whether the motor
vibrates and generates
unusual noise during
operation.
Adjust the gains again.
5. The servo drive model or
motor model is set
improperly.
Check the motor model
(H00.05) and drive model
(H01.10) stored in the bus
encoder.
Check the servo drive
nameplate and set the servo
drive model (H01.10) and
motor model properly
according to section "Servo
Drive Model and Nameplate"
in SV670P Series Servo Drive
Hardware Guide.
6. The motor is stalled due
to mechanical factors,
resulting in overload during
operation.
Check the reference and
motor speed (H0b.00)
through the software tool or
keypad.
● References in the position
control mode: H0b.13
(Input position reference
counter)
● References in the speed
control mode: H0b.01
(Speed reference)
● References in the torque
control mode: H0b.02
(Internal torque reference)
Check whether the reference
value is not 0 but the motor
speed is 0 rpm in the
corresponding mode.
Eliminate the mechanical
factors.
7. The servo drive is faulty.
The fault persists after the
servo drive is powered off
and on again.
Replace the servo drive.
Note
When E620.0 occurs, stop the servo drive for at least 30s before further operations.
● E625.0: Brake abnormality enabled
Cause
Confirming Method
Solution
The brake fails when it is
released.
Check if the motor shaft end
is held by the brake when
the brake release signal is
active.
1. Check the brake wiring.
2. Replace the Brake motor.
