Error Cause
F0022
The fault is caused by the following events:
Power stack fault
♦ (1) dc link overcurrent =short-circuit of
IGBT
♦ (2) short-circuit of dc link chopper
♦ (3) earth fault.
Ø Frame sizes A to C (1),(2),(3)
Ø Frame sizes D to E (1),(2)
Ø Frame size F (2)
Since all these faults are assigned to one
signal on the power stack, it is not possible to
establish which one actually occurred.
F0023
One phase is interrupted at the VSD output.

Diagnosis and troubleshooting
Check wiring of the 3 phases at the VSD output and at
the motor terminals
Check if the stator winding of the motor is interrupted
Replace the VSD
Check the following:
1. The fan must turn when the VSD is running
2. The pulse frequency (P1800) must be set to default
value 4 kHz
The fault cannot be masked while the options module
(AOP or BOP) is connected
Replace the fan
0: Check if the motor is connect to the VSD
1-40: Check if the motor data in P304-311 are correct
Check the type of motor wiring required (star, delta)
Reset VSD to factory setting and reparameterize
1. Ensure firmware version (r0018) is version 1.17 or
higher and
2. Replace I/O board (contact customer service)
Check the data
Exchange the I/O module
Check data flow
Exchange I/O module
