How to fix overvoltage on gefran ADV200 SP DC Drives?
- GGeorge JohnsonAug 15, 2025
An overvoltage in Gefran DC Drives typically occurs due to energy recovered from the motor, causing the voltage arriving at the drive power section to exceed the maximum threshold set by the PAR 560 Mains voltage parameter. To resolve this, you can try extending the deceleration ramp, using a braking resistor between terminals BR1 and BR2 to dissipate the recovered energy, or utilizing the Vdc Control function.
