7. Check the wiring of the
braking resistor and braking unit
»Correct the wiring
8. Tighten the terminal or
replace the damaged cable
9. Correct the wiring
10. Check the solutions for
interference suppression
1. The motor insulation is
damaged or the motor is
overheated
2. Grounding problem
caused by damaged motor
cable
3.The drive is damaged
4.The load is too heavy
5. Settings for acceleration
or deceleration time is too
short
6.The drive is running a
special purpose motor or a
motor larger than the drive
rated capacity
7. A magnetic contactor
(MC) on the output side of
the drive has turned on or
off
8. V/F set incorrectly
1. Check the insulation
resistance
2. Check the motor power cable
3. Check the resistance between
the cable and the terminal.
4. Short circuit on drive output
side or grounding causes
register damage.
5. Measure the current flowing
into the motor
5. Check the motor capacity
6. Calculate the torque required
during acceleration according to
the load inertia and acceleration
time. If the required torque is
insufficient, check the motor
capacity.
7. Install a sequence controller
to ensure the MC does not open
or close when the drive is
outputting voltage.
