11.1.53 Fault 11 - Output phase supervision, Subcode S4 - Additional closed loop output phase
fault during PM StartAngleID run
Cause
The measurement of current tells that there is no current in 1 motor phase.
It is possible to set different responses in the application for this fault. See parameter group Protections.
Troubleshooting
Do a check of the motor cable and the motor.
11.1.54 Fault 12 - Brake chopper supervision
Cause
There is no brake resistor.
The brake resistor is broken.
A defective brake chopper.
Troubleshooting
Do a check of the brake resistor and the cabling.
If they are in good condition, there is a fault in the resistor or the brake chopper. Ask instructions from the local distributor.
11.1.55 Fault 13 - AC drive undertemperature
Cause
Too low a temperature in the heat sink of the power unit or in the power board. The heat sink temperature is below -10 °C (14 °F).
Troubleshooting
Add an external heater near the AC drive.
11.1.56 Fault 14 - AC drive overtemperature, Subcode S1 - Overtemperature warning in unit, board,
or phases
Cause
Overheating detected in AC drive.
Heat sink temperature is over 90 °C (194 °F). Overtemperature alarm is issued when the heat sink temperature goes over 85 °C
(185 °F).
In 525–690 V, FR6: Heat sink temperature is over 77 °C (170.6 °F). Overtemperature alarm is issued when the heat sink temperature
goes over 72 °C (161.6 °F).
Troubleshooting
Do a check of the actual amount and flow of cooling air.
Examine the heat sink for dust.
Do a check of the ambient temperature.
Make sure that the switching frequency is not too high in relation to the ambient temperature and the motor load.
For FR10-FR11 Standalone: check door filters, and clean or replace if needed.
11.1.57 Fault 14 - AC drive overtemperature, Subcode S2 - Overtemperature in power board
Cause
Overheating detected in AC drive.
Heat sink temperature is over 90 °C (194 °F). Overtemperature alarm is issued when the heat sink temperature goes over 85 °C
(185 °F).
In 525–690 V, FR6: Heat sink temperature is over 77 °C (170.6 °F). Overtemperature alarm is issued when the heat sink temperature
goes over 72 °C (161.6 °F).
Troubleshooting
Do a check of the actual amount and flow of cooling air.
Examine the heat sink for dust.
Do a check of the ambient temperature.
Make sure that the switching frequency is not too high in relation to the ambient temperature and the motor load.
For FR10-FR11 Standalone: check door filters, and clean or replace if needed.
