Functional sequence when MP_refType=Switch, no changing Dir
For linear measurement using a rotary encoder, a reference pulse is produced
at each revolution of the encoder. During the reference run the first reference
pulse traversed after the trip dog for reference end position is closed is evalu-
ated. This ensures that the same reference pulse is always evaluated.
For linear measurement using a rotary encoder, HEIDENHAIN recommends
using the
MP_refType=Switch, changing dir method.
