Code Error message shown on

Sub-code Description
12 Motor OT
Condition: Motor overtemperature alarm. Possible causes:
- Load cycle too heavy
- The motor is installed in a place where the ambient temperature is too high
- If the motor is provided with a blower: the fan is not working
- If the motor is not provided with a blower: the load is too high at slow speeds. Cooling the fan on the mo-
tor shaft is not sufficient for this load cycle.
- The motor is used at less than the rated frequency, causing additional magnetic losses.
Solution:
- Change the processing cycle.
- Use a cooling fan to cool the motor.
13 Drive overload
Condition: Drive overload alarm.
The overload threshold of the accumulator of the I²t drive thermal image has been exceeded.
Solution: Check that the size of the drive is suitable for the application.
14 Motor overload
Condition: Motor overload alarm.
The current absorbed during operation is greater than that specified on the motor data plate. The overload
threshold of the accumulator of the I²t motor thermal image has been exceeded.
Solution:
- Reduce the motor load.
- Increase the size of the motor.
15 Bres overload
Condition: Braking resistor overload alarm.
The current absorbed by the resistor is greater than the rated current. The overload threshold of the ac-
cumulator of the I²t braking resistor thermal image has been exceeded.
Solution: Increase the Watt value of the braking resistor
16 Phaseloss Condition: Power phase loss alarm.
Solution: Check the mains voltage and whether any protections upstream of the drive have been tripped.
17 Opt Bus fault Condition: Error in the configuration stage or communication error.
XXX0H-X If the first digit to the left of “H” in the alarm sub-code is 0, the error regards a communica-
tion problem.
XXXXH-X If the first digit to the left of “H” in the alarm sub-code is other than 0, the error regards a
configuration problem.
Solution: For configuration errors, check the configuration of the bus communication, type of bus, ba-
udrate, address, parameter setting.
For communication errors verify wiring, resistance of terminations, interference immunity, timeout settings.
For further details, please refer to the user guide for the specific bus.
18 Opt 1 IO fault Condition: Error in the communication between Regulation and I/O expansion card in slot 1
Solution: Check that it has been inserted correctly, see chapter 11.5.
19 Opt 2 IO fault Condition: Error in the communication between Regulation and I/O expansion card in slot 2 or 3
Solution: Check that it has been inserted correctly , see chapter 11.5.
20 Not Used 1
21 External fault
Condition: External alarm present.
A digital input has been programmed as an external alarm, but the +24V voltage is not available on the
terminal.
Solution: Check that the terminal screws are tight
22 Not Used 2
23 Overspeed
Condition: Motor overspeed alarm.
The motor speed exceeds the limits set in the PAR 4540 Overspeed threshold
Solution:
- Limit the speed reference.
- Check that the motor is not driven in overspeed during rotation.
24 Speed ref loss
Condition: Speed reference loss alarm; occurs if the difference between the speed regulator reference
and the actual motor speed is more than 100 rpm. This condition occurs because the drive is in the current
limit condition. It is only available in the Flux Vect OL mode.
Solution: Check the drive load conditions
