will only output half of the PUU number. If P5-19 is set to a negative value, the output of E-cam
curve will be inverted compared with that is set to a positive value. If using firmware version
earlier than v1.038 sub48, after value of P5-19 is changed, users have to re-engage E-Cam to
make the modification become effective. If Bit 2 of P5-88.X is set, a new E-Cam curve scaling will
be effective immediately when its value is changed.

Changing P5-19 will only change the position of E-Cam. The pulse number from master axis
required for E-Cam to rotate a cycle remains the same. That is, it only changes the value of
Y-axis of the E-Cam curve; scale of X-axis remains the same. Therefore, the moving distance of
the slave axis and operating speed are both changed. To allow the operating speed synchronize
with the moving distance that has been changed, the pulse number of the master axis (ratio of
P5-84/P5-83) shall be adjusted based on the proportional scale. See Figure 2.60.
