ACH580-01 Installation
2340
Short circuit
Short-circuit in motor
cable(s) or motor
Check motor and motor cable for
cabling errors.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Cycle the power to the drive.
2381
IGBT overload
Excessive IGBT
junction to case
temperature. This fault
protects the IGBT(s)
and can be activated by
a short circuit in the
motor cable.
Check motor cable.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
3130
Input phase loss
Programmable fault:
31.21
Supply phase loss
Intermediate circuit DC
voltage is oscillating
due to missing input
power line phase or
blown fuse.
Check input power line fuses.
Check for loose power cable
connections.
Check for input power supply
imbalance.
3181
Wiring or earth fault
Programmable fault:
31.23
Wiring or earth fault
Incorrect input power
and motor cable
connection (ie. input
power cable is
connected to drive
motor connection).
Check input power connections.
3210
DC link overvoltage
Excessive intermediate
circuit DC voltage.
Check that overvoltage control is on
(parameter
30.30 Overvoltage
control
).
Check that the supply voltage
matches the nominal input voltage of
the drive.
Check the supply line for static or
transient overvoltage.
Check brake chopper and resistor (if
present).
Check deceleration time.
Use coast-to-stop function (if
applicable).
Retrofit drive with brake chopper and
brake resistor.
Check that the brake resistor is
dimensioned properly and the
resistance is between acceptable
range for the drive.
3220
DC link undervoltage
Intermediate circuit DC
voltage is not sufficient
because of a missing
supply phase, blown
fuse or fault in the
rectifier bridge.
Check supply cabling, fuses and
switchgear.
3381
Output phase loss
Programmable fault:
31.19
Motor phase loss
Motor circuit fault due
to missing motor
connection (all three
phases are not
connected).
Connect motor cable.
