4.13 Motor data identification
For linear motors (p0300 = 4xx), p1959 is pre-set so that only the q inductance, the
commutation angle offset and the high inertia mass are measured (p1959.05 = 1 and
p1959.10 = 1), as generally the travel limits do not permit longer travel distances in one
direction.
