000A Over-voltage
during acceleration
･The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
200kVA or more.
(2) A power factor improvement capacitor
is opened or dosed.
(3) A system using a thyrister is connected
to the same power distribution line.
･A restart signal is input to the rotating
motor after a momentary stop, etc.
･Insert a suitable input reactor.
･ Use
(auto-restart) and
(ride-through control).
000B Over-voltage
during deceleration
･The deceleration time
is too short.
(Regenerative energy is too large.)
･
(dynamic braking resistor) is off.
･
(over-voltage limit operation) is off.
･The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
200kVA or more.
(2) A power factor improvement capacitor
is opened and dosed.
(3) A system using a thyrister is connected
to the same power distribution line.
･Increase the deceleration time
.
･Install a dynamic braking resistor.
･Enable
(dynamic braking resistor)
･Enable
(over-voltage limit
operation).
･Insert a suitable input reactor.
000C Over-voltage
during constant-speed
operation
･The input voltage fluctuates abnormally.
(1) The power supply has a capacity of
200kVA or more.
(2) A power factor improvement capacitor
is opened or dosed.
(3) A system using a thyrister is connected
to the same power distribution line.
･ The motor is in a regenerative state
because the load causes the motor to run
at a frequency higher than inverter output
frequency.
･Insert a suitable input reactor.
･Install a dynamic braking resistor.
000D Inverter over-load
･The acceleration time
is too short.
･The DC braking amount is too large.
･The V/F setting is improper.
･A restart signal is input to the rotating
motor after a momentary stop, etc.
･The load is too large.
･Increase the acceleration time .
･Reduce the DC braking amount
and the DC braking time .
･Check the V/F parameter setting.
･ Use
(auto-restart) and
(ride-through control).
･Use an inverter with a larger rating.
000E Motor over-load
･The V/F setting is improper.
･The motor is locked up.
･ Low-speed operation is performed
continuously.
･An excessive load is applied to the motor
during operation.
･Check the V/F parameter setting.
･Check the load (operated machine).
･ Adjust
to the over-load that the
motor can withstand during operation in a
low speed range.
000F Dynamic braking resistor
over-load 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
･Over-torque reaches to a defection level
during operation.
･Enable
(over-torque trip
selection).
･Check system error.
0010 Overheat
･The cooling fan does not rotate.
･The ambient temperature is too high.
･The vent is blocked up.
･A heat generating device is installed does
to the inverter.
･The thermistor in the unit is broken.
･ Restart the operation by resetting the
inverter after it has cooled down enough.
･The fan requires replacement if it does not
rotate during operation.
･ Secure sufficient space around the
inverter.
･Do not place any heat generating device
near the inverter.
･Make a service call.
* You can select a trip ON/OFF by parameters.
