V/F curve
Four modes: linear torque characteristic curve, self-set V/F curve, torque reduction characteristic
curve (1.1 to 2.0 power), square V/F curve
Acceleration/Deceler
ation curve
2 modes: linear Acceleration/Deceleration and S curve Acceleration/Deceleration. 4 sets of
ACC/DEC, time unit 0.01s selectable, longest time: 650.00s.
Rated output voltage
Using the power supply voltage compensation function, the rated voltage of the motor is 100%, which
can be set within the range of 50 to 100% (the output cannot exceed the input voltage)
Voltage
auto-adjustment
While power supply voltage fluctuates, it can auto-keep constant output voltage.
Auto energy-saving
running
While under V/F control mode, according to load situation, auto-optimize output voltage to save
energy.
Auto-limit current
Auto-limit the current while running to prevent over current break trouble.
Instant power off
treatment
Uninterrupted operation through bus voltage control during instantaneous power loss
