Range of jog frequency:0.20Hz~50.00Hz; Acc/Dec time of Jog operation:
0.1~60.0s, Interval of Jog operation is also settable.
Multi-step speed running
Multi-step speed running can be realized by internal PLC or control
terminal
Internal PI Be able to form simple control system easily
Auto-energy saving operation
V/F curve is optimized automatically according to the load condition to
realize energy-saving operation.
Auto voltage regulation(AVR)
When source voltage changes, the modulation rate can be adjusted
automatically, so that the output voltage is unchanged.
Auto current limiting
Operating current is limited automatically to avoid frequent tripping of the
drive.
Auto adjusting of carrier
frequency
Optional function. The carrier frequency can be adjusted automatically
according to the load condition.
