Chapter 6 - Parameter Description [FU2]
100
FU2-07: Dwell Frequency
FU2-08: Dwell Time
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.
☞
Note:
Do not set the Dwell frequency above run
frequency. Otherwise, it may lead to operation fault.

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.
