JSS57P Integrated Stepper Servo Motors

1.Features

• Adopt advanced 32-bit motor control dedicated DSP chip and vector closed-loop control technology; 
• The default work is in closed loop mode, no loss of step, and it also supports working in open loop mode；
• Increase the output torque and running speed of the motor;
• The current level is intelligently adjusted according to the load, reducing the temperature rise of the motor, locking the current, and adjusting the closed-loop peak current；
• Adapt to various mechanical load conditions (including low-rigidity loads such as pulleys and pulleys) without adjusting the gain parameters；
• The position command smoothing filter can be set, the motor runs smoother, the vibration is lighter, and the acceleration and deceleration dynamic performance is improved；
• Zero-speed static capability without vibration after positioning；
• Support single and double pulse input, pulse response frequency up to 200KHZ
• Support 15 fixed subdivisions, and support software to set any subdivision (200~65535)；
• Support modbus RTU protocol on RS232, position and speed control controlled by communication；
• Support monitoring of motor operating conditions, including speed, position deviation, bus voltage, operating current, etc.
• Voltage range: DC+24V~48V；
• With over-current, over-voltage, positional tolerance and other protection；

（4）Status indication

PWR: Power Indicator. The green indicator lights when power is applied.

ALM: Fault indicator. Red light flashes 1 time within 3 seconds: Over-current or phase-to-phase short-circuit fault; Red light flashes continuously 2 times in 3 seconds: Over-voltage fault; Red light flashes continuously in 7 seconds 7 times: position error tolerance alarm.

6.DIP switch setting

JSS57P uses a six-digit dial switch to set the filter time, motor rotation direction and subdivision accuracy.

SW1, filter time setting. The default on=3ms, off=25ms, the larger the filtering time, the smoother the motor runs and the lower the noise. Moreover, in the on state, the filtering time can be flexibly set by the upper computer software setting.

SW2, motor rotation direction setting. On=CW, off=CCW.

SW3, SW4, SW5, SW6：Subdivision setting

The default file segmentation defaults to 400, which can be modified by the host computer software.
