Motion Control
Partially engaged
This is applicable for cutting operations with or without marks. For the cutting operation with
marks, use the Capture function to have the E-Cam engaged. For the cutting without marks,
use the Compare function to generate virtual marks for the Capture function to capture the
7
position data. The E-Cam curve includes the acceleration zone, synchronous speed zone, and
deceleration zone. After the E-Cam curve (acceleration, synchronous speed, deceleration
zones) is executed, the clutch disengages. The reset zone is completed with a PR command
and then it waits for the next trigger signal to have the clutch engaged. With this method,
you can create an E-Cam curve with a larger synchronous speed zone based on the maximum
moving distance of the cutter. This is suitable for applications with the cutting length smaller
than the waiting zone. For applications with the cutting length greater than the maximum moving
distance of the cutter, disengage the E-Cam and have the material feeder continue to operate,
and then the E-Cam re-engages when the servo receives the trigger signal.
