Inverter damping resistor
Use this resistor when rapidly decelerating or stopping the motor very often or to reduce the deceleration time when the load has great inertia.
It is a resistor for consuming energy during dynamic braking.
Inverter damping resistor
About Inverter damping resistor
A braking resistor is necessary when the motor is stopped in a short time, as with a mechanical brake, or the load-side machine rotates the motor (regenerative operation).
Features
Rapid braking (short-time deceleration)
Use this resistor if the motor needs to decelerate rapidly or if an overvoltage "OP" trip occurs when the motor decelerates to stop.
Regenerative operation
・Use this resistor when the motor is in a regenerative state continuously in such a case as lowering a lifting machine or winding out for tension control.
・Use this resistor when the load fluctuates even during constant-speed operation, placing the motor in a regenerative state, as with a press machine.
