was generated, the attempt counter is reset.
Solution: Too many Desaturation alarms.
Adopt the proposed solutions for the Desaturation alarm.
9 Heatsink OT [HOT]
Condition: Heatsink temperature too high alarm
- Verify the correct operation of the cooling fan.
- Check that the heatsinks are not clogged
- Check that the openings for the cabinet cooling air are not blocked.
10 HeatsinkS OTUT [HSOT]
Condition: IGBT module temperature too high or too low alarm
- Verify the correct operation of the cooling fan.
- Check that the heatsinks are not clogged
- Check that the openings for the cabinet cooling air are not blocked.
11 Intakeair OT [IOT]
Condition: Input air temperature too high alarm.
- Check correct fan operation
- Check that panel cooling air openings are unobstructed.
- Check temperature in electrical panel.
12 Motor OT [MOT]
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 motor shaft is not sufficient for this load cycle.
- The motor is used at less than the rated frequency, causing additional magnetic losses.
- Change the processing cycle.
- Use a cooling fan to cool the motor.
13 Drive overload [DOL]
Condition: Drive overload alarm.
- The inverter output current has exceeded the allowed overload value.
- The overload cycle has exceeded the allowed values.
- Check that the load is not excessive.
- Check that accelerations are not excessive.
- Check that the overload cycle is within allowed limits.
14 Motor overload [MOL]
Condition: Motor overload alarm.
The current absorbed during operation is greater than that specified on the motor data plate.
- Reduce the motor load.
- Increase the size of the motor.
15 Bres overload [BOL]
Condition: Braking resistor overload alarm.
The current absorbed by the resistor is greater than the rated current.
- Check the size of the braking resistor.
- Check the condition of the braking resistor.
16 Phase loss [PHL]
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 [OPTB]
Condition: Error in the configuration stage or communication error.
If the first digit to the left of “H” in the alarm sub-code is equal to 0, the error relates to a communication problem.
If the first digit to the left of “H” in the alarm sub-code is other than 0, the error relates to a configuration problem.
