How can I initialize a Trinamic stepper motor driver using the encoder N channel?

First, you need to set the encoder for correct interpretation of the N signal. This depends on your encoder.
  • Set clr_once for a single initialization / latch of the encoder counter upon the next N event. Additionally, set clr_enc_x to clear the encoder to 0.
  • In order to set the actual motor position to 0 as well, activate latch_x_act.
  • Stop the motor after detection of the encoder event and then subtract the latched position from x_actual.
