How to fix gefran ADL500 Inverter DC link overvoltage alarm?
E
Eric ScottAug 23, 2025
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 ADL500?
M
Meghan HarrisAug 26, 2025
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 Inverter shows an overcurrent alarm?
S
Samantha MitchellAug 27, 2025
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.

Jason WallaceAug 28, 2025
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 ADL500 Inverter?
D
derek85Aug 29, 2025
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 if my gefran ADL500 displays a message during power card recognition?
J
Jose HigginsSep 17, 2025
If your Gefran Inverter displays a message during recognition of power cards, and it's not possible to drive the motor, it may be because the power card is configured for a drive that is incompatible with the regulation card, the configuration of the power card is not compatible with the regulation card, or the configuration required is not available on the power card. Download the correct configuration on the power card.

What does a speed reference loss alarm mean on a gefran ADL500?
M
Michael DownsSep 6, 2025
A speed reference loss alarm on your Gefran Inverter means the difference between the speed regulator reference and the actual motor speed is more than 100 rpm, usually because the drive is in the current limit condition. Check that the load is not excessive.

Barbara WilsonSep 4, 2025
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.
