Example of a modulo axis with cyclic output and track length < modulo length
Cam track data/Explanation
Representation
● Modulo length: 360°
● Track length: 0-120°
● Output cam defaults: SOC=10°, EOC=20°
Output cam is output cyclically every 10-20°,
130-140°, 250-260°, etc.
If the direction of movement is reversed at 50°, for
example, the 10-20° output cam will be output
again.

Example of a modulo axis with non-cyclic output
The example (following table) below shows a modulo axis with non-cyclic output, next-track-
cycle start mode, and varying enable positions and axis reference positions.
● Enable A, axis reference position 0°, positive direction of rotation:
output cam A is output.
If the cam track is not exited, output cam A switches multiple times when the direction is
reversed. The cam track output is terminated on exiting the cam track.
● Enable A, axis reference position 240°, negative direction of rotation:
output cam C is output during the next cycle.
● Enable B, axis reference position 120°, positive direction of rotation:
output cam B is output.
● Enable C, axis reference position 240°, positive direction of rotation:
output cam C is output.
