Why is my Gefran Inverter showing a DC link undervoltage alarm?
A DC link undervoltage alarm may occur in your Gefran Inverter due to the mains voltage being too low or overextended voltage drops or poor cable connections (e.g. loose contactor terminals, inductance, filter). To resolve this, check the connections and mains voltage.
How to fix gefran ADL530 DC link overvoltage alarm?
If your Gefran Inverter displays a DC link overvoltage alarm because the energy recovered from the voltage arriving at the drive power section is too high, you can extend the deceleration ramp. Alternatively, use a braking resistor connected to the specific terminals to dissipate the energy recuperation.
What causes a motor overtemperature alarm on a gefran ADL530?
A motor overtemperature alarm on your Gefran Inverter can be triggered by several factors: * A load cycle that is too heavy. * The motor being installed in an environment with a high ambient temperature. * A faulty motor blower fan. * Excessive load at slow speeds if the motor lacks a blower. * Operating the motor below its rated frequency. To address this, change the processing cycle or use a cooling fan to cool the motor.
What to do if gefran ADL530 shows an overcurrent alarm?
If your Gefran Inverter is showing an instantaneous overcurrent protection intervention alarm, it might be caused by incorrect settings of the current regulator parameters. You should check the current regulator parameters (menu 12.3) and inspect the wiring towards the motor.
How do I troubleshoot a ground fault alarm on a gefran ADL530?
To troubleshoot a ground fault alarm (ground short circuit alarm) on your Gefran Inverter, check the drive and motor wiring. Also, ensure that the motor is not grounded.
Why is the heatsink temperature too high on my gefran ADL530 Inverter?
A heatsink temperature too high alarm on your Gefran Inverter can occur if the cooling fan isn't working correctly, the heatsinks are clogged, or the openings for cabinet cooling air are blocked. Verify the correct operation of the cooling fan, check that the heatsinks are not clogged, and ensure that the openings for the cabinet cooling air are not blocked.
What causes a motor overload alarm on a gefran ADL530?
A motor overload alarm on your Gefran Inverter indicates that the current absorbed during operation is greater than that specified on the motor data plate. To resolve this, reduce the motor load or increase the size of the motor.
What does a desaturation condition mean on my gefran ADL530 Inverter?
A desaturation condition on your Gefran Inverter signifies an instantaneous overcurrent in the IGBT bridge. Try switching the drive off and then on again. Also, check the condition of the braking resistor isolation. If the alarm persists, contact the technical service centre.
What should I do if my gefran ADL530 is overloaded?
If your Gefran Inverter is overloaded, check that the load is not excessive, that accelerations are not excessive, and that the overload cycle is within allowed limits.
How to resolve a braking resistor overload alarm on a gefran ADL530?
A braking resistor overload alarm on your Gefran Inverter means the current absorbed by the resistor is greater than the rated current. Check the size and condition of the braking resistor.
