V/F curve
(Voltage-frequency character)
Base frequency can be set from 5~500Hz arbitrarily,
and there are three kinds of curve: constant
torque ,Dec torque 1 and Dec torque 2.
Torque boost
Manual Setting: 0~20% of rated output, Auto-boost:
Automatically boost torque according to output
current.
Auto energy-saving running
Adjust output voltage and slip compensation properly
according to output current, which will make the
motor working in highest efficiency.
Acc./Dec time setting
0.1~6000seconds can be set continuously, and S type
and line type can be selected.
Braking
Dynamic braking
Over 75% (External braking resistor)
DC braking
It is selected respectively at start and stop, and its
frequency is 0~15Hz, the action voltage is 0~15%, and
the action time is 0~20.0 second or act continuously.
Auto current-limiting function
Fast auto current-limiting function ensures not to occur
the over-current during the accelerate process or under
the impact load.
