- The setting of the regenerative resistor (regenerative option) is incorrect. Check the regenerative resistor (regener
REMEDY · Step by step
How to fix it?
Extend the deceleration time and add a regenerative resistor
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
