Probable Causes / Corrective Actions
01 IPM
ERROR
A fault signal is detected from
Inverter’s IPM power
transistors block.
1- A short-circuit or ground fault occurred at the
U,V,W motor output. Check motor connection.
2- The IPM temperature may be too high because
of the Inverter’s cooling fan has stopped. Check
cooling fan.
3- An over-current may be occured on the output
of inverter so that inverter may have overheated
because of the incorrect parameter setting. Check
the parameter setting.
4- The main supply voltage may be too low.
Check the L1, L2, L3 voltages.
5- The main contactors of motor output have not
to change its position while the inverter driving
the motor. If the contactors drop after the inverter
stops driving and waits as the brake delay time,
increase the contactor delay time. Check the
contactor’s supply voltage if the contactor
changes its position while the inverter driving the
motor.
02 LOW
DC
BUS
The DC Bus voltage is below
the undervoltage detection
level.
If mains power is active:
Vbus < 400 V
If battery power is active:
Vbus < (Vbat x %70)
If UPS power is active:
Vbus < 200V
1- If mains power is active: The main supply
voltage may be too low. Check the L1, L2, L3
voltages.
2- If battery power is active: Check the battery
voltage on the terminals L1 and L3.
03
HIGH DC BUS
The DC Bus voltage exceeded
the overvoltage detection
level.
If mains power is active:
Vbus > 715 V
If UPS power is active:
Vbus > 420V
1- Braking resistor may not be connected
properly. Check broken or disconnected wiring.
2- Braking resistor’s resistance may be incorrect.
Be sure that the braking resistor is suitable for
Inverter's power and motor power.
04 OVER
CURRENT
The inverter output current
exceeded the overcurrent
detection level.
1- Because of the acceleration time of the elevator
is too short motor current may increase. Decrease
the acceleration parameter PA.
2- Check the V/f characteristics. Decrease Vmid
(Middle frequency voltage) and Vmin (Minimum
frequency voltage).
3- The motor being used has a capacity more than
Inverter's maximum motor capacity. Check the
Inverter's motor power.
05 PAR.DATA
CORRUPT
The parameters of the inverter
is erased or corrupted.
1- Change the parameters of the inverter to
factory defaults. Then reenter your configuration.
06 MOTOR
OVER LOAD
The motor overload protection
function has operated based on
the internal electronic thermal
value.
1- Check the motor rated current.
2- Check the “Motor Setup - Thermal Mod”
parameter. The parameter may be too low.
