1.1 Overview

HSS57 is 2 phase nema 23 series hybrid stepper servo driver. It adopts new generation 32 bit DSP and vector control technology, which can avoid the stepper motor losing steps and ensure the accuracy of the motor. The torque reducing is much lower than open loop stepper motor when it is at higher speed. The high speed performance and torque are enhanced in a great extent. Meanwhile the current control is based on the load, that can reduce the motor temperature rising effectively, then can extend the using life of the motor. The build-in place in position and alarm output signal can help the upper monitor to monitor and control. The function of position ultra difference alarm can ensure the machine work safely. The closed loop system is an ideal improvement and a good replacement of open loop system, Besides that, it also have some function ofAC servo motors, but price is just half ofAC servo.

1.2 Features

1.2.1 Stepper motor closed loop system, never lose step.

1.2.2 Improve motor output torque and working speed.

1.2.3Automatic current adjustment based on load, lower temperature rising.

1.2.4 Suitable for all mechanical load conditions (include low rigidity belt pulley and

wheel), no need to adjust gain parameter.

1.2.5 Motor work smoothly and low vibration, high dynamic performance at

acceleration and deceleration.

1.2.6 No vibration from high speed to zero speed

1.2.7 Drive nema 23 series 2N.m closed loop stepper motor.

1.2.8 Pulses response frequency can reach 200KHZ

1.2.9 16 kinds microsteps choice, highest 51200microsteps/rev.

1.2.10 Voltage range: DC24V~50V

1.2.11 Over-current, over-voltage and position ultra difference protection function.

1.3Applications

Closed loop stepper system can be applied to all kinds small automatic equipment and Instruments, such as engraving machine, special industrial sewing machine, stripping machine, marking machine, Dispensing machine, cutting machine, laser phototypesetting, graph plotter, NC machine, automatic, assembly equipment and so on.

3.5．Statusindication
PWR：power indicator light : When power is on, the green light is on.
ALM：Alarm indicator light: If the red light is flicker one time within 3 seconds, that means over current or interphase short circuit; If the red light is flicker twice within 3 seconds, that means over voltage; if the red light is flicker three times within 3 seconds, that means position ultra difference or the encoder connector is disconnected.
