6.1 Jumpers

Descriptions for the jumpers are provided in the following list:

cs-receptable-j10.gifFigure 8. CS Receptacle (J10)
  • CS (J10) is the current limit setting. CS connects a resistor to GND for current-limit setting. This receptacle is meant for easy implementation of axial-lead through-hole resistors. Otherwise, R4 can be used for substitution of surface-mount resistors.
    • adv-receptable-j8.gifFigure 9. ADV Receptacle (J8)
  • ADV (J8) is the lead angle setting. ADV connects a resistor to GND for lead angle setting. This receptacle is meant for easy implementation of axial-lead through-hole resistors. Otherwise, R2 can be used for substitution of surface-mount resistors.
    • rmp-receptacle-j9.gifFigure 10. RMP Receptacle (J9)
  • RMP (J9) is the acceleration ramp-rate control setting. RMP connects a resistor to GND for setting the acceleration ramp-rate control. This receptacle is meant for easy implementation of axial-lead through-hole resistors. Otherwise, R3 can be used for substitution of surface-mount resistors.
    • speed-command-input-select-header-j3.gifFigure 11. Speed Command Input Select Header (J3)
  • Select (J3) is used to configure motor speed-control resources for the PWM pin. Set the PWM jumper to PWMIN for sending a PWM signal to the PWM pin to control motor speed. See Figure 4 for more details. Set the PWM jumper to Analog with J2 connected for using potentiometer (R5) to control motor speed. See Figure 3 for more details.
  • J7 and J11 Connections are placeholders for an I2C interface, so they can be ignored.
    • potentiometer-power-header-j2.gifFigure 12. Potentiometer Power Header (J2)
  • Potentiometer Power (J2) provides voltage from the V1P8 pin of the DRV10974 device to power the potentiometer. This header must be jumpered to use the potentiometer.
