How to fix gefran ADL500 Inverter 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.
