E-Cam system status
The E-Cam system has three states, Stop, Engage, and Pre-engage. When the E-Cam function
is enabled, you can use P5.088.D to promptly monitor the system’s current status. The following
section explains each state, as shown in Figure 7.3.2.8.
1.
Stop state (P5.088.D = 0): the clutch is disengaged and the system continues to check the
engagement condition (P5.088.Z). If the engagement condition is met and the initial lead
pulse (P5.087) is not set, the clutch engages. If you have set the initial lead pulse, the
system enters the Pre-engage state. When the E-Cam function is disabled, the system is
also in the stop state.
2.
Engage state (P5.088.D = 1): the clutch is engaged and the system continues to check the
disengagement condition (P5.088.U). If one of the three disengagement conditions,
“Disengagement control with DI”, “Immediate stop after disengagement, or “Decelerate to
stop after disengagement” (P5.088.U = 1, 2, or 6) is met, the system is stopped. If the
condition “Enter cyclic mode after disengagement (P5.088.U = 4)” is met, the system
enters the Pre-engage state.
3.
Pre-engage state (P5.088.D = 2): the clutch is disengaged. If pulses from the master axis
reach the initial lead pulse number or the pre-engaged pulse number for each cycle, the
clutch engages and the system enters the Engage state.
