Meaning
Probable Causes / Corrective Actions
04
OVER
CURRENT
The inverter output
current exceeded the
over current 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 are 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.
07
POWER
FAILURE
The main supply
voltage L1, L2, L3
oscillates unusually.
1- The main supply voltage is too low.
2- An open-phase error occurred at the input
power supply.
3- A momentary power loss occurred.
4- The wiring terminals for the input power supply
are loose.
5- The voltage fluctuations in the input power
supply are too large.
08
AUTO TUNE
FAILS
A fault occurred
during auto tuning in
open loop mode. Auto
tune operation cannot
be completed.
1- Check motor connection. Motor connection
may not be done properly.
2- Motor contactor may not be switching. Be sure
that the motor contactor closes when inverter is
running.
09
OVER
SPEED
The speed read from
encoder is too high.
1- Motor speed may be higher than the reference
speed. Check motor setup in the menu.
2- Compare the pulse number setting in the menu
“Motor Setup - Encoder Resolution” with the
encoder pulses and correct if necessary.
10
BAD
ENCODER
SGNL
The encoder signals
oscillate unusually.
1- Check encoder connection and encoder voltage.
2- Check the connection between encoder and
motor.
3- If the encoder cable is not shielded, use a
shielded cable.
4- If the motor cable is not shielded, use a shielded
cable.
5- Encoder cable may be placed too close to motor
cable. Motor cable and encoder cable channels
should be separate. Minimum distance between
cables should be at least 10cm.
6- Encoder may be grounded at both the motor
side and inverter side. If the encoder is grounded
at motor side, disconnect the grounding at inverter
side.
