Setting the mechanical system
Fig. 80: Parameterizing the mechanical properties of the axis
The "Setting the mechanical system " dialog is only displayed when an encoder
was configured for the safety technology.
The mechanical properties of the axis are set in this dialog:
● In
● In the "Feed constant" (P–0–3221.0.4) field, specify the distance traveled by
● In
● In the "Modulo value" (P–0–3221.0.6) field, specify at which numerical value
● In the "Polarity (position, velocity, acceleration)" (P–0–3221.0.1) dialog sec-

absolute format (see scaling dialog), the input is a unipolar value (modulo
format) or bipolar value (absolute format).

"Output revolutions of load gearbox" (P–0–3221.0.3) fields, parameterize a
gearbox present between motor and load. For this purpose, enter the gear
ratio by using the number of integral motor revolutions (input revolutions)
and the corresponding number of integral gear output revolutions (output
revolutions). If no encoder gearbox is used, set both values to "1".
The field is only active with a rotary motor.

to be smaller than the value entered in "Maximum travel range".
The field is only active, when the "Position data processing format " has
been set to modulo format (see scaling dialog).
tion, set the appropriate polarity for the machine axis depending on the
mounting situation.
– This applies to rotatory motors: Clockwise rotation of motor output shaft
(with view to the motor output shaft) causes positive velocity feedback
value (positive polarity).
– This applies to linear motors: Motion of primary part in the direction of
the cable connection side causes positive velocity feedback value (posi-
tive polarity).
