Configuring the linear/modular axis

You can choose to use a linear axis or a modular axis depending on your actual application.
The linear axis has a restricted traversing range, which is the factory setting of the
SINAMICS V90 PN servo drive.
The modular axis has an unrestricted traversing range. The value range of the position
repeats itself after a value is specified in p29245. You can use the modular axis by setting
the following parameters additionally:
Parameter Range
p29245
p29246 1 to 2147482647
Note
After modifying parameter p29245, you must perform the referencing operation again.
