Linear Measurement Via Rotary Encoder - HEIDENHAIN TNC 415 Technical Manual

2.1.3 Linear measurement via rotary encoder

Machine parameter MP1350.x = 2
For linear measurement using a rotary encoder a reference pulse is produced on each revolution of
the encoder. It must be ensured that, after switching on the machine, always the same reference
pulse is evaluated. This can also be achieved by using the trip dog "Reference end-position".
