6.6.2 Definition of the reference point coordinate
By parameterizing the encoTRive, the drive-internal position sensor can be adapted to
the application-specific rotary axis with gearbox. Since the encoTRive or the
underlying drive profile ProfiDrive only supports integers, the gear ratio "i" must be
parameterized as a fraction with numerator P001[0] and denominator P001[1]. The
parameter P006 “Travel range” defines the maximum position value of the application
before the actual value of position P100 restarts from zero.

The activation of the rotary axis functionality takes place as soon as the parameter
value P006 is > 0.
The following conditions must be observed during parameterization:
 Gear ratio numerator P001[0] < P006 Travel range
 Gear ratio numerator P001[0] < 32768
 Travel range P006 > 0
 Gear ratio numerator P001[0] ≥ Gear ratio denominator P001[1]
