  1. Product Overview


      Thank you for choosing the Rtelligent R series digital stepper driver.

      Based on the new 31-bit DSP platform, and adopting the micro-stepping technology and PID current control algorithm design. Rtelligent R series stepper drive surpasses the performance of common analog stepper drive comprehensively. With the features of low noise low vibration low heating and high-speed high torque output it allows the stepper motor to deliver full performance benefits.
 

   
3R130 Digital Stepper Motor Driver

      The 3R130 driver has built-in pulse command S-type acceleration/deceleration function and limit frequency optional function, which is set by DIP switch. In addition, the micro-stepping level and current level can be selected by the DIP switch. There are 16 micro-stepping levels and 16 current levels selections. The driver integrates overvoltage, undervoltage and overcurrent protection, and its input and output control signals are photoelectric isolation.

    2.3 Driver installation requirements

      Install the drive in a vertical or horizontal position with the front facing forward and the top facing up for heat dissipation.

   When assembling, take care to avoid drilling debris and other foreign objects falling inside the drive.

   Use M3 screws to fix it during installation.

   When there is a vibration source nearby (such as a drill press, etc.), use a vibration absorber or install an anti-vibration rubber gasket.

   When multiple drives are installed in the control cabinet, please pay attention to the space to ensure sufficient heat dissipation; if necessary, the cooling fan can be configured to ensure good heat dissipation conditions in the control cabinet.

    3.2 power supply input 

  The operating power supply of the driver is AC power, and the input voltage ranges is 110- 230V. Please pay attention to confirm the local grid voltage, do not exceed the maximum voltage of the driver.

  The input power supply specification is single-phase AC power. Install an EMI device in front of the drive terminals to filter out electromagnetic interference from the power grid.


    3.3 Motor Connection

   The 3R130 driver can drive low-resistance, low-inductance, three-phase hybrid stepper motors below 130 series.

         Common three-phase stepper motors have 3-wire and 6-wire outlets.             

    3.4 Control signal wiring

      3.4.1  PUL, DIR port: connection for pulse command

  The R series driver signal interface is pulsed, and the 3R130 can receive three types of pulse command signals.

  The upper controller can be a pulse signal generating device such as a PLC, a single chip microcomputer, a control card, or a controller.

  The acceptable pulse level of the 3R130 driver is: 3.3V~24V (serial resistance not necessary for the application of PLC)


 
monopulse (PUL + DIR)
double - pulse (CW +CCW)
orthogonal pulse (A/B orthogonal pulse
 

      3.4.2  ENA Port: Used to enable or disable 

       When the optocoupler is off, the driver outputs current to the motor; when the internal optocoupler is turned on, the driver will cut off the current of each phase of the motor to make the motor in a free state, and the stepping pulse is not responded.

  When the motor is in an error state, the enable is automatically turned off. The level of the ENA signal can be set to the opposite.


      3.4.3  Input IO Signal: IN1, IN2 

       IN1 and IN2 are input signals with optocoupler isolation and can accept differential or single-ended digital inputs. This signal is the input logic and input pin of the driver and increases the trigger condition for driver motion. Please contact the Rtelligent's engineer for specific use.
 

      3.4.4 Output IO Signal: ALM, RDY

  ALM and RDY are the pins of the driver logic output. The default is defined as ALM alarm output and RDY ready signal output. The drive alarm status and ready status can be output to the external upper system. The output signal can also be defined as other logic outputs.

      The DIP switches SW1, SW2, SW3, and SW4 are used to set the current value of the driver output to the motor.
      Normally, the current is set to not exceed the rated current value of the motor (effective value).If your system has high requirements for heating, you can reduce the current to reduce the heat generated by the motor.

  DIP switch SW5, SW6, SW7, SW8 are used to set the number of pulses required for each revolution of the motor.

       Motor speed = command pulse frequency ÷ per revolution pulse

  Motor stroke = number of command pulses per revolution


    4.3 Filter Selection

      The DIP switch SW9 is used to select the function of pulse smoothing of drive. “off” means this function is deactivated, while “on” means that it is activated.
 

    4.4 Bandwidth Selection

      SW0 is used to select the bandwidth of drive. The maximum passing pulse frequency is 200KHZ when it is of and 1MHZ when it is on.
 

    5. Driver working status LED indication

LED status Driver status
Green indicator is on for long time Drive not enabled
  Green indicator is flickering driver working normally
  one green indicator and one red indicator  driver overcurrent
   one green indicator and two red indicator  driver input power overvoltage
