
000B Overvoltage during
deceleration
 The deceleration time  is too short.
(Regenerative energy is too large.)
 Increase the deceleration time .
 Overvoltage limit operation  is set
to 1. (Disabled).
 Set overvoltage limit operation  to
0, 2, 3.
 The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
500kVA or more.
(2) A power factor improvement capacitor is
opened and closed.
(3) A system using a thyristor is connected
to the same power distribution line.
 Insert a suitable input reactor.

000C Overvoltage during
constant-speed
operation
 The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
500kVA or more.
(2) A power factor improvement capacitor is
opened or closed.
(3) A system using a thyrister is connected
to the same power distribution line.
 Insert a suitable input reactor.
 The motor is in a regenerative state
because the load causes the motor to run
at a frequency higher than the inverter
output frequency.
 Install an optional dynamic braking
resistor. (optional)

000D Inverter overload
 The acceleration time ACC is too short.  Increase the acceleration time .
 The DC braking amount is too large.  Reduce the DC braking amount 
and the DC braking time .
 The V/F setting is improper.  Check the V/F parameter setting.
 A restart signal is input to the rotating
motor after a momentary stop, etc.
 Use  (auto-restart) and 
(ride-through control).
 The load is too large.  Use an inverter with a larger rating.

000E Motor overload
 The V/F setting is improper.  Check the V/F parameter setting.
 The motor is locked up.  Check the load (operated machine).
 Low-speed operation is performed
continuously.
 An excessive load is applied to the motor
during operation.
 Adjust  to the overload that the
motor can withstand during operation in a
low speed range.

003E Main module
overload
 The carrier frequency is high and load
current has increased at low speeds
(mainly at 15Hz or less).
 Raise the operation frequency.
 Reduce the load.
 Reduce the carrier frequency.
 When an operating motor is started up at
0Hz, use the auto-restart function.
 Set carrier frequency control mode
selection f316 to 1 (carrier frequency
with automatic reduction).

000F Dynamic braking
resistor overload trip
 The deceleration time is too short.
 Dynamic braking is too large.
 Increase the deceleration time .
 Increase the capacity of dynamic braking
resistor (wattage) and adjust PBR
capacity parameter .
*

0020 Over-torque trip 1
 Over-torque reaches to a detection level
during operation.
 Enable  (over-torque trip selection).
 Check system error.

0041 Over-torque trip 2
 Output current reached f601 or more
and maintain in f452 during power
running.
 Power running torque reached f441 or
more and maintain in f452 during
power running.
 Reduce the load.
 Increase the stall prevention level or
power running torque limit level.
* This marking trips can be selected valid or invalid by parameters.
