Changes in the parameters Z121.14– and Z121.13– become only then effective after
switching off and on again the modulo position actual value calculation (Z121.1– bit 4) in
Z121.17– Modulo position actual value!
If the load gear is used as well for weighting the Z136.3– Target position in the operation
mode Position control (Z109.1– set operation type = 4), the changed gear values are
accepted only at an inhibit and of a new enable of the operation type -4.
121.15 Modulo revolutions
Modulo value in complete revolutions.
This parameter defines the point in which the revolutions of the Modulo position should
overflow ("turnover") to 0.
The parameter is used at the calculation of the Z121.17– Modulo position actual value
as well as at the back calculation of the Modulo position set value (Z136.3– target posi-
tion) in the internal standardization at an active weighting (Z136.2– mode bit 6 = 1).
Modulo value = 1:
The revolutions at the gear output are irrelevant for the Modulo position actual value.
Modulo value = 0:
The revolutions at the gear output will be added to the Modulo position actual value with-
out modulo division. With it the Modulo function is switched off for the position actual val-
ue (Z121.17–) and the position set value (Z136.3– Target position).
The parameter Modulo revolution will be effective only if the following condition is com-
plied with:
Modulo revolutions < (2

-1) * Output revolutions Z121.14– / Input revolutions Z121.13–
121.16 Rotation position resolution
This parameter contains the value of the rotation position resolution and defines the value
of the rotation weighting. A value of 3600000 corresponds with a LSB value of
0.0001
degrees.
Rotation resolution = 0: Only the angle of the gear output will be transferred 1:1 in Modulo
position actual value! The revolutions at the gear output are not used and the modulo cal
-
culation is not executed.
The Modulo function and the weighting for the position set value (Z136.3– Target posi-
tion) is also switched off at value 0.
An exorbitant value in the rotation position resolution can cause an unrequested overflow
in
Z121.17– Modulo position actual value. Therefore the following condition applies:
Modulo revolutions * Rotation position resolution < 2
