Disposal methods
Overcurrent
at accel
⒈
Check whether the motor has got
short circuit or partial short circuit
and whether the output wire is good.
⒉
Extend the acceleration time.
⒊
The configuration of the inveter is
not reasonable and its capacity should
be increased.
⒋
Lower the torque and increase the
set value
Overcurrent
at constant
speed
⒈
Check whether the motor has
got short circuit and whether the
insulation of the output wires is good.
⒉
Check whether the motor is rotating
with some external jamming force
and whether there is a sudden change
of mechanical load.
