order, 1.7 order, and 1.2 order)
Acc/Dec curve
3 modes: linear Acc/Dec, S ramp Acc/Dec and auto Acc/Dec; Acc/Dec time
(maximum: 60 hours) and unit (second or minute) are settable.
Jog
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.
Operating
function
Methods of inputting operating
commands
Commands can be input by terminals and serial ports.
Methods of setting up
frequency
Digital setting; Analog voltage/current setup; pulse frequency setup; set via serial
port and different setting modes are selectable
Auxiliary frequency reference
Realize flexible fine tuning of auxiliary frequency.
Pulse output terminal
0~50kHz pulse signal output. Signals like frequency setting and output frequency
can be output.
