Simple PLC and multi-speed runningIt can realize a maximum of 16 segments speed running via the built-in PLC or control terminal.
Built-in PIDIt is easy to realize process-controlled close loop control system.
voltage regulation
It can keep constant output voltage automatically in case of change of mains voltage.
Torque limit and control"Shovel" characteristics, automatic limit on the torque on running time,  preventing frequent over-current trip; closed loop vector mode can realize the torque control
customized functionsPeripherals self-detection upon
It can conduct safety detections on the peripherals upon power-on, including earth and short circuit detections.
Shared DC bus
It can realize the function that multiple inverters share the DC bus.
JOG keyProgrammable key: Select the forward and reverse rotations/jog operation command.
Traverse frequency controlMultiple triangular-wave frequency control function.
Fast current limit functionWith fast current limit algorithm built in to reduce the probability of over-current alarm; to improve the anti-jamming capacity of the whole machine.
