21. Er.430: Control power undervoltage
Cause:
•
220 V drive: normal value: 310 V, overvoltage level: 200 V
•
380 V drive: normal level: 540 V, overvoltage level: 380 V
Cause Conrming Method Corrective Action
1. The control power is
unstable or fails.
•
Check whether the servo drive is in
the process of cutting off the control
power (L1C, L2C) or instantaneous
power failure occurs.
Re-power on the servo drive.
If the fault is abnormal power
failure, keep power supply
stable.
•
Check whether the input voltage of
control cables satises the following
specication:
220 V drive:
Effective value: 220 to 240 V
Allowed error: -10% to 10% (198 to
264 V)
380 V drive:
Effective value: 380 to 440 V
Allowed error: -10% to 10% (342 to
484 V)
Increase the power capacity.
2. The control power
cables are in poor
contact.
•
Check whether the control cables
are well connected and whether the
voltage of the control cables satises
the preceding specication.
Re-connect it or replace the
control cables.
22. Er.500: Servo motor overspeed
Cause:
•
The actual speed of the servo motor exceeds the overspeed level.
Cause Conrming Method Corrective Action
1.The UVW phase
sequence is incorrect.
•
Check whether the UVW phase
sequence on the servo drive side is
consistent with that on the motor side.
Connect the UVW cables
according to the correct
phase sequence.
2. The setting of H0A-08
is incorrect.
•
Check whether the overspeed level
is smaller the actual maximum motor
speed.
Overspeed level = 1.2 times of
maximum motor speed (H0A-08 = 0)
Overspeed level = H0A-08 (H0A-08 ≠
0, and H0A-08 < 1.2 times of maximum
motor speed)
Reset the overspeed
level according to actual
mechanical requirement.
