What causes Motor overtemperature prealarm on gefran ADP200?
If the Gefran Inverter shows a motor overtemperature prealarm, and this causes a % value of threshold compared to PAR 4532 MotorOT thr, the value set is too low for duty cycle.
What to do if gefran ADP200 Inverter shows Overcurrent [OC] alarm?
If your Gefran Inverter displays an instantaneous overcurrent protection intervention alarm, this might be due to incorrect current regulator parameter settings. To resolve this: - Check the current regulator parameters (menu 17). - Check the wiring towards the motor.
Why gefran ADP200 shows DC link undervoltage alarm?
If your Gefran Inverter shows a DC link undervoltage alarm, check the connections. The problem is caused by the voltage arriving at the drive power section being too low compared to the Undervoltage [UV], the mains voltage being too low or overextended voltage drops, or poor cable connections (e.g. loose contactor terminals, inductance, filter).
What causes motor overload alarm on Gefran Inverter?
If your Gefran Inverter displays a motor overload alarm, it means the current absorbed during operation is greater than that specified on the motor data plate. To solve this: - Reduce the motor load. - Increase the size of the motor.
How to resolve braking resistor overload alarm on gefran ADP200 Inverter?
If you're getting a braking resistor overload alarm on your Gefran Inverter, it means that the current absorbed by the resistor is greater than the rated current, or the overload threshold of the accumulator of the I²t braking resistor thermal image has been exceeded. You should: - Check the size of the braking resistor. - Check the condition of the braking resistor. - Use a braking resistor with higher energy value and change the parameters on 22.5 - FUNCTIONS/BRES OVERLOAD menu.
What to do if Gefran Inverter was enabled with no supply voltage?
Check the Gefran Inverter power supply.
What to do if Gefran Inverter exceeds the number of automatic restarts after Desaturation alarm?
If your Gefran Inverter shows that the number of attempted automatic restarts after the Desaturation alarm was exceeded, adopt the proposed solutions for the Desaturation alarm, because there are too many Desaturation alarms.
How to reset Emergency stop alarm on Gefran Inverter?
Eliminate the reason for which the Stop key on the keypad was pressed and reset the Gefran Inverter.
How to troubleshoot configuration or communication error on Gefran Inverter?
If the Gefran Inverter displays an error in the configuration stage or communication error, and 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. For configuration errors, check the configuration of the Bus communication, Bus type, Baudrate, address parameter setting. For communication errors, verify wiring, resistance of terminations, interference immunity, timeout settings.
How to resolve intake air temperature too high alarm on Gefran Inverter?
If the Gefran Inverter displays an intake air temperature too high alarm, check correct fan operation.
