Probable Cause Conrming Method Corrective Action
6. Locked-rotor
occurs due to
mechanical factors,
resulting in very
heavy load during
running.
Check the running reference and motor
speed (200B-01h) through Inovance servo
commissioning software or the keypad:
Running reference in position control:
200B-0Eh
(Input position reference counter)
Running reference in speed mode:
200B-02h
(Speed reference)
Running reference in torque mode:
200B-03h
(Internal torque reference)
Check that the running reference is
not 0 but the motor speed is 0 in the
corresponding mode.
Eliminate mechanical factors.
7. The servo drive
is faulty.
The fault persists after the servo drive is
powered on again.
Replace the servo drive.
E1.630: Overheat protection for locked-rotors
Cause:
The actual motor speed is lower than 10 rpm but the torque reference reaches the limit. The
duration reaches the value set in 200A-21h.
Probable Cause Conrming Method Corrective Action
1. Power output
(UVW) phase
loss or incorrect
phase sequence
occurs in the
servo drive.
Perform motor trial run when there is no
load and check the motor wirings.
Correct the wiring or replace the
cables.
2. The servo
drive UVW cable
or the encoder
cable is broken.
Check wirings.
Correct the wiring or replace the
cables.
3. Locked-rotor
occurs due to
mechanical
factors.
Check the running reference and motor
speed (200B-01h) through Inovance servo
commissioning software or the keypad:
Running reference in position control:
200B-0Eh
(Input position reference counter)
Running reference in speed mode:
200B-02h
(Speed reference)
Running reference in torque mode:
200B-03h
(Internal torque reference)
Check that the running reference is
not 0 but the motor speed is 0 in the
corresponding mode.
Eliminate mechanical factors.
