A2B4 Short circuit
Short-circuit in motor cable(s) or
motor.
Check motor and motor cable for cabling
errors.
Check motor and motor cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable
(see
reference value).
A581 Fan Cooling fan feedback missing.
Check fan operation and connection.
Replace fan if faulty.
A5A0
Safe torque off
Programmable
warning Safe torque off function is active, i.e.
safety circuit signal(s) connected to
connector STO is lost.
Check safety circuit connections.
2310 Overcurrent
Output current has exceeded
internal fault limit. In addition to an
actual overcurrent situation, this fault
may also be caused by an earth
fault or supply phase loss.
Check motor load. Check motor and motor
cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable
(see
reference value).
Check if refrigerant compressor selected is
correct on the drive (from the main screen
press two times "OK" button).
2330 Earth leakage
Drive has detected load unbalance
typically due to earth fault in motor
or motor cable.
Check motor and motor cable for cabling
errors.
Check motor and motor cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable
(see
reference value).
2340 Short circuit
Short-circuit in motor cable(s) or
motor
Check motor and motor cable for cabling
errors.
Check motor and motor cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable
(see
reference value).
3130 Input phase loss
Intermediate circuit DC voltage is
oscillating due to missing input
power line phase or blown fuse.
Check input power line fuses.
Check contactor K1.
Check for loose power cable connections.
Check for input power supply imbalance.
3181
Wiring or earth
fault
Incorrect input power and motor
cable connection (i.e. input power
cable is connected to drive motor
connection).
Check input power connections.
3210
DC link
overvoltage Excessive intermediate circuit DC
voltage.
Check that the supply voltage matches the
nominal input voltage of the drive.
Check the supply line for static or transient
overvoltage.
Check autotransformer output voltage (if
present).
