JSS42P Integrated Stepper Servo Motors

1.Features

• Use the advanced 32-bit ARM chip and vector closed-loop control technology;
• Works in closed-loop mode by default without losing step;
• Improve the output torque and operating speed of the motor;
• The current is intelligently adjusted according to the load, reducing the temperature rise of the motor, locking the current, and the closed-loop peak current is adjustable;
• Adapt to various mechanical load conditions (including low-rigidity pulleys, etc.), no need to adjust gain parameters;
• Built-in position command smoothing filter function, the motor runs smoother, the vibration is lighter, and the acceleration and deceleration dynamic performance is improved. The filter function can be canceled before leaving the factory;
• After positioning is completed, zero-speed static capability without vibration;
• Supports single and double pulse input, pulse response frequency up to 200KHZ;
• Supports 15 fixed subdivisions, and supports using software to set any subdivision(200~65535);
• Voltage range：DC+24V；
• With over-current, over-voltage, position out of tolerance and other protections

4.Interface definition

（1）Power input port

（2）Control signal port

（3）Status indication

PWR: power indicator light. When power is on, the green indicator light is on.

ALM: fault indicator light. Flashing red light once within 3 seconds: over-current or phase-to-phase short circuit fault; Flashing red light 2 times continuously within 3 seconds: over-voltage fault; Flashing red light 7 times continuously within 3 seconds: position error alarm.

5.DIP switch setting

JSS42P uses a five-digit DIP switch to set the motor rotation direction and subdivision accuracy.

SW1: motor rotation direction setting. on=CW, off=CCW.

SW2, SW3, SW4, SW5: Subdivision settings.

This subdivision number can be modified by the upper computer software.
