FB1.INITSIGNED

Description

This parameter sets whether the initial value of the feedback read from the feedback device will be set as a signed or as an unsigned value.

0 = Unsigned

1 = Signed

The drive internal process for the feedback initialization is as follows:

  1. Reads the position feedback.
  2. Adds the origin to the feedback.
  3. Determines modulo from Step 2 by the actual feedback bits.
  4. Sets the position feedback sign according to FB1.INITSIGNED.
