Main Control
Function
Frequency resolution Digital Setting: 0.01Hz; Analog Setting: max frequency × 0.1%
Start frequency 0.40Hz ~ 20.00Hz
Torque boost Auto torque boost, manual torque boost 0.1% ~ 30.0%
V/F curve
Five modes: constant torque V/F curve, 1 V/F curve mode by user and 3 kinds of
torque-derating modes (2nd power, 1.7th power, 1.2nd power)
Accelerate/Decelerate curve
Two modes: linear Acc/Dec, S curve Acc/Dec; seven kinds of Acc/Dec time,
Maximum: 6000 minutes, the time unit (minute or second) is selectable
DC brake
Initial frequency of DC braking: 0~15.00Hz
Braking time: 0~60.0 s
Braking current: 0~80%
Power consumption brake Built-in brake unit, can connect external brake resistor
Jog Range of jog frequendy: 0.1Hz~50.00Hz, Acc/Dec time of jog 0.1~60.0s
Built-in PI Easy to form close loop control system
Multi-step speed running Multi-step speed work through built-in PLC or control terminals
Textile wobble frequency Adjustable preset frequency and center frequency
Auto voltage regulation
(AVR)
When the power system voltage changes, maintain the constant of output voltage
Auto energy saving running
Auto-optimize V/F curve according to the load condition to realize energy saving
operation
Auto current limit Auto-limit running current to avoid trip caused by overcurrent
Fix-length control The frequency inverter will stop running when reaching the fixed length
