Series: L7
Main circuit overvoltage
drive
Meaning: The main circuit voltage exceeds the overvoltage detection value; The initial detection values are as follows: 200V class: DC410V400V class: DC820V; The deceleration time setting is too short, resulting in excessive regenerative energy from the motor; The supply voltage is too high; The braking unit/braking resistor is not operating
