CONTREX M-Traverse - Manual (Page 93)

3 - 46
Example of an Edge Based Profile with no Home Offset.
Home Seek moves the Follower mechanism in the reverse direction (toward the
reverse limit). When Home Seek locates the Home Sync sensor, it ramps down at the
Accel/Decel (CP-60) rate to zero. This causes the Follower mechanism to overshoot
the Home Sync sensor and the M–Traverse compensates with a forward, triangulated
Accel/Decel move that aligns the Follower mechanism with the Home Sync sensor.
This profile is used in both web scan and level wind applications.
