Description / Cause.
Cause
Remedy
Low voltage
Output turns off when the
DC link voltage is less than
180V.
Line voltage is low.
Insufficient line capacity.
Increase line voltage.
Check the AC line voltage
at full rated current.
Electronic
Thermal
Output turns off when the
inverter calculates that the
motor is overheating.
Protection is not provided
when driving multiple
motors or a motor having
more than 4 poles.
Motor has overheated.
Load is greater than
inverter rating.
ETH set too low.
Inverter has been operated
at low speed for too long.
Reduce load weight and
operating duty.
Install larger inverter.
Adjust ETH level.
Install an external cooling
fan.

Inverter
hardware fault
An error occurs in the
control circuitry of the
inverter.
Communication
Error
Inverter cannot
communicate with the
keypad.
Cooling fan fault
Fault condition occurs in the
cooling fan.
Obstructed air flow.
Damaged cooling fan.
Clean the ventilating slot.
Replace the cooling fan.
Output Inhibit
Output turns off when a
digital input (set to 2,
Output Inhibit) is closed.
The drive output is instantly
turned off and the motor
coasts to stop. As soon as
the input is opened, the
drive will resume previous
operation (if in run, the drive
will immediately accelerate
to the set speed).
The digital input is active
(Closed).
Eliminate the cause of fault
at external terminal.
External fault A
contact input
Output turns off when a
digital input (set to 18, Ext
Trip: A Contact) is closed.
The digital input is active
(Closed).
Eliminate the cause of fault
at external terminal.
External fault B
contact input
Output turns off when a
digital input (set to 19, Ext
Trip: B Contact) is closed.
Speed reference
input is lost
Speed Reference is Lost
(when set to Analog input
0-10V or 0-20mA or
RS485). Operation
continues by the method
set in I62.
No speed command is
applied to V1, I or RS485
inputs.
Check wiring of inputs
V1, I and RS485 and the
speed reference level.
