In addition, the initial lead pulse number of the master axis before
engagement is set by ECamLeadPulseBeforeEngaged parameter ID375
(P5.087). The E-CAM begins executing the profile when E-CAM function is
enabled and the number of master pulses from ID375 (P5.087) occur, which is
considered a type of offset from the immediate engagement type.
Figure 202 - Clutch Engagement Lead Pulses
Condition for Disengagement
When the E-CAM function is enabled and the clutch is engaged, the slave axis
follows master pulses based on the cam curve. When the slave axis completes
the cam cycle, it is stopped either by disabling the E-CAM function or
disengaging the clutch. This action is shown in Figure 203
. If the clutch is
disengaged, the slave axis remains stationary regardless of the action of the
master axis.
