Types of applications

Alternating movement

Area

Example of an alternating axis

This is for revolving transfer machines and hydraulic presses.

The alternating movement of the axis is "to-and-fro".

The rotation speed can vary greatly during the machine cycle.

Outputs are positioned in both directions. The forward program can differ from the reverse program. There may be a prohibited zone defined as a protective zone

(brake control).

In this application, the encoder resolution is 4000 pulses per cycle. The permitted movement zone is 3992 pulses. Recalibration is performed at 90° of the mechanical origin (0) which is not accessible.
