Condition: IGBT modules temperature too high or too low alarm
Solution:
- 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.
Condition: Intake drive air temperature too high alarm.
Solution:
- Check correct fan operation
- Check that the heatsinks are not clogged
- Check temperature in electrical panel.
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.
Solution:
- Change the processing cycle.
- Use a cooling fan to cool the motor.
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.
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.
Condition: Braking resistor overload alarm.
The current absorbed by the resistor is greater than the rated current. The overload threshold of
the accumulator of the I²t braking resistor thermal image has been exceeded.
Solution: Increase the Watt value of the braking resistor
Condition: Power phase loss alarm.
Solution: Check the mains voltage and whether any protections upstream of the drive have been
tripped.
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
communication 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, baudrate, 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.
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 10.5.
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 10.5.
Condition: Error in the communication between Regulation and Encoder feedback card.
Solution: Check that it has been inserted correctly , see chapter 10.5.
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
