A2S series driver is a low-power drive series product independently developed by COTRUST, which supports power of 100W~1kW.
A2S mainly aims at the servo market of high-speed pulse input control, and communicates with the upper computer through Modbus RTU protocol for monitoring and debugging.
A2S series servo also has rich input/output interfaces, supporting the return function, trial operation and various communication control modes. With the trigger mode, it can
complete various control tasks such as position, speed, torque and return to the origin.
Characteristic
①The power range is 0.1 kw-0.4 kw; 0.75KW-1KW；
②Support high-speed pulse input and external ID input control mode;
③Support 17Bit/23Bit bus encoder;
④Support MODBUS RTU communication.
