Chapter 5 Troubleshooting

5.1 Over Current (OC)

ocA

ocd

Over-current
during acceleration

Over-current
during deceleration

Over current

Check if there is any

between the U, V, W and motor

short circuits and

grounding

Yes

Remove short circuit
or ground fault

Reduce the load or
increase the power
of AC motor drive

Reduce torque
compensation

Suitable torque
compensation

Yes

Maybe AC motor drive
has malfunction or error
due to noise. Please
contact with DELTA.

Can acceleration
time be made longer?

Can deceleration
time be made longer?

Reduce load or increase
the power of AC motor
drive

Check braking
method. Please
contact DELTA

Reduce load or increase
the power of AC motor
drive

Has load changed
suddenly?

Check if
acceleration time
is too short by
load inertia.

Check if
deceleration time
is too short by
load inertia.

Increase accel/decel
time

Check if load is too large
