information
A32
Overcurrent Current
that
flew is higher
than the
permissible
current of the
servo amplifier.
1. A ground fault or short occurred at the servo
motor power cable.
(A ground fault or short due to the
deterioration of insulator.)
<Check method>
The alarm occurs even if power is switched on
after disconnection of servo motor power wires in
servo motor-side terminal.
Repair the cable.
2. External dynamic brake fault.
<Check method>
The alarm does not occur when the power is
switched on after disconnection of servo motor
power lines in external dynamic brake-side
terminal.
1. Check the parameter
and dynamic brake
sequence.
2. Change the external
dynamic brake.
3. Servo amplifier fault.
<Check method>
The alarm occurs even if the power is switched
on after disconnection of the servo motor power
lines from the servo motor power output (U, V,
and W).
Change the servo
amplifier.
4. Servo motor fault.
<Check method>
The alarm does not occur when the power is
switched on after disconnection of servo motor
power lines in servo motor side terminal.
Change the servo motor.
5. External noise caused the overcurrent detection
circuit to misoperate.
<Check method>
1. Check if the environment is affected by the
noise of surrounding electromagnetic valve,
magnetic contactor, relay, etc.
2. Check the servo amplifier and servo motor for
grounding.
Take the grounding and
noise reduction
techniques.
6. Encoder fault.
Change the servo motor.
