Simple PLC, multistage speed operation

Jog frequency range: 0.00Hz～50.00Hz. Jog acceleration/deceleration time is 0.0s～6500.0s.

Built-in PID

Through the built-in simple PLC or control terminal to achieve up to 16-speed operation

Automatic voltage adjustment (AVR)

It is convenient to realize the process control closed-loop control system

Over voltage and over current stall speed control

When the grid voltage changes, it can automatically keep the output voltage constant

Rapid current limit

Minimize over-current faults to protect the normal operation of the inverter

Torque limit and control

The "shovel" feature automatically limits the torque during operation to prevent frequent over-current trips; closed-loop vector mode can realize torque control
