After creating an E-Cam curve based on the maximum moving distance of the cutting axis, set the
master pulse number of disengaging time (P5.089) according to the cutting length. After reaching
the disengaging pulse number or receving the cutting complete signal, the clutch disengages and
continues with a zero-speed PR speed command to stop the cutter. Then, it uses another PR
position command to return the cutter to the initial position, as shown in Figure 7.3.8.5. The setting
methods are as follows:
Master axis signal source: set P5.088.Y to 0; it means the source of the master axis is the
1.
capturing axis. In the Capture function, this capturing axis refers to the setting of P5.039.Y
for the signal source of the master axis.
Engagement condition: set P5.088.Z to 2; it means the clutch engages as soon as the first
2.
data is captured and the signal is input through DI7 to the servo drive.
Disengagement condition: set P5.088.U to E; it means the clutch disengages when the
3.
master axis pulse number reaches the pulse number set in P5.089, the slave axis
decelerates to stop, and the E-Cam function is disabled.
To set the subsequent PR procedure after the clutch disengages, set the PR number to be
4.
executed in P5.088.BA in hexadecimal.
Set the PR procedures:
5.
Procedure 1: set the PR commands for execution when the cutting machine is activated.
PR#1 confirms the Capture function is disabled. PR#2 confirms the E-Cam function is
disabled. PR#3 jumps to PR#C. PR#C sets the capturing amount to 1. PR#D enables the
Capture function. PR#E enables the E-Cam function.
Procedure 2: set the subsequent PR commands after the clutch disengages. PR#A sets
the zero-speed command to stop the cutting axis. PR#B sets the position command to
return the cutting axis to the initial position.
