Features

Multi encoder support: It can support differential encoder; open collector encoder;  rotating transformer encoder and so on.

Won’t stop working instantly when face suddenly power-off: When face suddenly power-off, the decreasing of voltage can be supplemented by the feedback energy from overloading. 

Control of over-voltage, over-current and losing speed: It restricts automatically of the current and voltage during operation to prevent the frequent trip caused by over-voltage and over-current. 

Restricting and controlling of the torque: It can restrict automatically to the torque during operation and prevent the frequent trip, closed-loop and vector control can achieve the control of torque. 

Operation with simple and easy PLC as well as Multi velocity: To the biggest extent, it can achieve16 stage speed operation by built-in PLC or control terminal.
