E-Gear Ratio And Scaling Of E-Cam Curve - Delta ASDA Series Application Notes

Introduction of E-Cam Operation
Example 2:
When using Macro 7 to create an E-Cam curve and R = 0.5 ~ 1.09 (when R < 1.0, cutting length
< cutter circumference), follow the instructions shown in Figure 2.57 to write macro commands
can avoid occurrence of error codes. Table in Figure 2.57 shows the setting range of waiting area
and constant speed area based on the S level.
S = 1 Wd = 0º~150º
Wd = 0º~(150º-∆χ)
Wd = 0º~(150º+∆χ)
S = 3 Wd = 0º~110º
Wd = 0º~(110º-∆χ)
Wd = 0º~(110º+∆χ)

2.6 E-gear Ratio and Scaling of E-Cam Curve

P5-19 and E-gear ratio of the slave axis will change the E-Cam scaling from issuing command to
output. See Figure 2.58.

The E-gear ratio of E-Cam axis is identical to the system's which specified by P1-44 and P1-45.
Change of slave axis' E-gear ratio will change the system's E-gear ratio; the system's E-gear
ratio will not be restored even when E-Cam is disengaged. Therefore, it is not suggested to
modify the scaling of E-Cam curve by P1-44 and P1-45 as this will also change the E-gear ratio
of the entire system. When E-cam is disabled, PR command will also refer to this E-gear ratio.
Effect brought by P5-19 is the same as the E-cam's E-gear ratio but only effective to E-Cam
system instead of the system's E-gear ratio. In this case, using P5-19 to change the scaling of
E-Cam curve is recommended. In terms of E-Cam's output, the effect of adjusting value of P5-19
is the same as adjusting the value of P1-44 /P1-45. When P5-19 = 0.5, the output of E-Cam axis
