ESS57 is a new type of integrated motor drive hybrid servo system with communication capabilities. It uses advanced 32-bit high-performance ARM chips and closed-loop control technology to prevent step loss, ensuring product accuracy; the high-speed torque decay is much lower than that of traditional open-loop drivers, significantly enhancing the high-speed performance and torque of stepper motors; it employs load-based current control technology, effectively reducing motor temperature rise and extending motor life; it includes built-in alarm output signals for easy monitoring and control by the host computer; the position out-of-tolerance alarm function ensures safe operation of processing equipment. It is an ideal upgrade from traditional open-loop stepper drives and can replace some traditional AC servo systems at a price only 50% of that of AC servo systems.

(3)Status indication
PWR: Power indicator light. When powered on, the green indicator light is on.
ALM: Fault indicator light. Red light flashes once within 3 seconds: over current or phase short circuit fault; red light flashes twice continuously within 3 seconds: over voltage fault; red light flashes seven times continuously within 3 seconds: position error exceeds the limit alarm.
6.DIP switch setting
ESS57 The six-bit code switch is used to set the filter time, motor rotation direction and subdivision accuracy.
SW1, motor rotation direction setting. on=CW, off=CCW.
