This function is used to output torque in an intended direction. It is useful in hoisting applications to get enough torque before a releasing mechanical brake. If the dwell time is set at ‘0’, this function is not available. In dwell operation, the inverter outputs AC voltage not a DC voltage.

☞Note: DC Injection Braking does not output torque to an intended direction. It is just to hold the motor.

To prevent undesirable resonance and vibration on the structure of the machine, this function locks out the potential resonance frequency from occurring. Three different jump frequency ranges may be set. This avoidance of frequencies does not occur during accelerating or decelerating. It only occurs during continuous operation.
