Economy Model adopt a pulse-style appearance design, equipped with a 32-bit ARM processor and advanced power angle closed-loop control algorithm, supporting Modbus-RTU, CANopen, and EtherCAT bus communication control. They are simple closed-loop stepper servo drives with cost close to pulse-type open-loop drives. Users can customize subdivision, adapt to closed-loop motors while being compatible with open-loop stepper motors, and directly set baud rate and station address via DIP switches. They feature low vibration, stable low-speed operation, built-in acceleration/deceleration control to improve start-stop smoothness, compatibility with 1000-line and 2500-line encoders, built-in control modes of cyclic synchronous position, cyclic synchronous speed, profile position, profile speed, and homing. Adopting standard RJ45 network connection, they realize stable operation with no step loss, low temperature rise, high speed and high torque, with convenient maintenance and extremely high cost performance.
