Steady-speed
precision
Vector control W/O PG: ≤ ± 0.1% (rated synchronous speed)
Vector control W/ PG: ≤ ± 0.02% (rated synchronous speed)
Torque response ≤ 40ms (vector control W/O PG)
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.
Quick current
limiting
The current limiting algorithm is used to reduce the inverter over current
probability, and improve whole unit anti-interference capability.
