Factory set:1.00Hz
F7.11
Zero speed torque
gain
Setting range: 0.0
～
500.0%
Factory set:100.0%
Zero speed value:
It is recognited as zero speed working state while frequency inverter frequency is lower than [F7.10]
Zero speed torque gain:
It is output torque while frequency inverter is zero speed woring. It is mainly used for keeping
certain tension at zero speed. This value take give torque as base, totally corresponding to torque give value.
Calculation formula:
Torque at zero speed=give torque*zero speed torque gain
Use this value to set output torque at zero speed and running state separately to meet requirement
