4.2 Pre-parameterising in the office
4.2.1 Parameters A, C and S
The permitted values of the parameters A, C, and S for the
drive you are using can be found in the appropriate axis-
specific supplement.
4.2.2 Parameters L and r (only with type SPC11-INC)
The parameters L and r are only queried when incremental
path measuring systems are used (e.g. positioning drive
DNCI-...-... in connection with type SPC11-INC).
With incremental path measuring systems, the SPC11
requires the following information:
– Nominal stroke length (L) of the drive (see type plate)
– Offset axis zero point (r) – offset between the end position
P.01 and the axis zero point (see Fig. 4/2).
