6.1 Jumpers

Descriptions for the jumpers are provided in the following list:

Figure 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.
Figure 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.
Figure 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.
Figure 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.
Figure 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.
