Built-in simple PLC multiple speeds

It realizes up to 16 speeds via the simple PLC function or combination of Di terminal states

Built-in PID

It realizes up to 16 speeds via the simple PLC function or combination of Di terminal states

Overvoltage/ Over current stall control

The current and voltage are limited automatically during the running process so as to avoid frequently tripping due to
overvoltage/over current
