4.3 Using an External Actuator

The DRV2625EVM-CT can be used with an external actuator. Follow the instructions below to attach an actuator to the OUT terminal block.

  1. Remove jumpers J8 and J9 which disconnects the on-board actuators from the DRV2625.
  2. Attach the positive and negative leads of the actuator to the green OUT terminal block keeping in mind polarity.
  3. Screw down the terminal block to secure the actuator leads.

Use the green terminal block when connecting an external actuator. The OUT+ and OUT– test points have low-pass filters and should only be used for oscilloscope and bench measurements.
