Commissioning
3.13 Commissioning of SIMOTICS L-1FN3 linear motors
Incremental measuring system
Example of an incremental sine/cosine encoder with a lattice pitch of 16000 nm and a zero
mark:
Image 3-50 Screen form for entering the encoder data
Note
A pole position identification is required for SIMOTICS L-1FN3 linear motors with
incremental measuring systems
The following techniques are possible to do this:
• The motion-based technique
• The saturation-based technique (1st harmonic)
For incremental measuring systems, generally, fine synchronization is performed at the zero
mark. When commissioning the system for the first time, the angular commutation offset
(p0431) must be pre-assigned, see Chapter "Determining the angular commutation offset /
maintaining the tolerance (Page 204)".
For third-party motors, a pole position identification routine to determine the angular
commutation offset cannot be entered.
