61 HB 13.0001-EN 3.0
As the position of the zero pulse with regard to the edge is not known before a reference
run, the following procedure is recommended:
1. Reference run with an absolute resolver position of 0.
2. Positioning of the rotor directly on the edge of the reference signal.
3. On the basis of the current actual position value, the distance between the zero
pulse and the edge can be identified. Furthermore, from the sign of the actual
position it can be identified whether referencing has been carried out to the zero
pulse in front of or behind the edge of the reference signal.
4. Then the absolute resolver position can be adapted according to the above
examples.
