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.

FU2-10 ~ FU2-16: Frequency Jump

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.

☞Note: When the reference frequency is set inside the jump frequency, the output frequency goes to the frequency marked by “n” symbol.

☞Note: If one frequency jump range is required, set all ranges to the same range.

FU2-19: Input/Output Phase Loss Protection (Bit Set)

This function is used to cut the inverter output off in case of phase loss in either input power or inverter output.
