Steady-speed
precision
Vector control W/O PG: ≤ ± 0.5% (rated synchronous speed)
Vector control W/ PG: ≤ ± 0.02% (rated synchronous speed)
Torque response
≤ 40ms (vector control W/O PG)
Torque boost
Automatic torque boost; manual torque boost(0.1% to 30.0%)
DC braking
DC braking frequency: 0.0Hz to max. frequency, braking time:
0.0 to 100.0 seconds, braking current value: 0.0% to 100.0%
Jogging control
Jog Frequency Range: 0.00Hz to max. frequency;
Jog Ac/deceleration time: 0.0s to 6500.0s
Multi-speed
operation
Achieve up to 16-speed operation through the control terminal
Built-in PID
Easy to realize closed-loop control system for the process control.
Automatic voltage
regulation(AVR)
Automatically maintain a constant output voltage when the voltage
of electricity grid changes
Torque limit and
control
"Excavator" feature - torque is automatically limited during the
operation to prevent frequent overcurrent trip; the closed-loop
vector mode is used to control torque.

Self-inspection of
peripherals after
power-on
After powering on, peripheral equipment will perform safety
testing, such as ground, short circuit, etc.
Common DC bus
Multiple inverter can use a common DC bus.
