The bus digital stepper driver series products are EtherCAT bus digital stepper drivers, which adopt the standard EtherCAT (COE) communication protocol and have built-in CIA402 motion control protocol for cycle synchronous position (CSP), cycle synchronous speed (CSV), track position (PP), track speed (PV), and return to zero (HM) modes. They use the latest 32-bit ARM processor and motor control algorithm to smoothly improve the torque of the motor during high-speed operation at low speeds; Built in button input and digital display output, can set slave station operation parameters such as ID number, baud rate, and running direction, and display the current status of the driver; Comes with 5 digital signal inputs.
