The operation of the fully engaged mode is based on the E-Cam curve. The E-Cam curve is
more complex and more difficult to create, so if the cutting length changes, you can only modify
the cutting length by setting the pre-engaged pulse number for each cycle (P5.092) or adjust the
E-Cam gear ratio (P5.084 / P5.083) and curve scaling (P5.019).
 Cutting length is greater than the E-Cam curve operating length
Select to enter cyclic mode after disengaging (P5.088.U = 4) and set the pre-engaged
pulse number for each cycle (P5.092). When the E-Cam enters the pre-engaged status,
the material feeder continues operating, but the cutting axis stops. The cutting axis
resumes operation until the pre-engaged pulse number for each cycle is met. The greater
the pre-engaged pulse number for each cycle, the longer the cutting length.
