ASDA Series Application Note Introduction of E-Cam Operation
March, 2015 2-45
PR#3: Specify the place where the captured data is saved in data array. In this example, the
E-Cam’s engaging time is controlled by the capture signal. Therefore, parameters
relevant to the capture function have to be set. The captured data can be stored anywhere
in data array. However, please note that since some data of E-Cam curves have been
saved in data array, it is necessary to avoid the area that is in use to ensure no safety
issue arises.
PR#4: Specify the amount of the captured data. Only one datum is required. The capture
function here is only for making E-Cam engaged. The captured value does not mean
anything.
PR#5: Initialize the capture function. Specify CN1 pulse input (P5-39.Y = 2) as the source for the
master axis of the capture function.
PR#6: Initialize E-Cam function. Specify CN1 pulse input (P5-88.Y = 2) as the master source;
Set the engaging time when capture function is enabled (P5-88.Z = 2); Set the
disengaging time when the moving distance has reached the setting value of P5-89
(P5-88.U = 2).When E-Cam disengaged, the system will call PR#10 (P5-88.BA = A)
automatically. To ensure PR#5 and PR#6 are carried out, set delay time to 1 ms in this
PR.
PR#7: Enable Capture function. Set P5-39.X to 1 in order to enable the capture function.
PR#8: Enable E-Cam function. Set P5-88.X to 1 in order to enable E-Cam function.
PR#10: After E-Cam disengaged, the system will call this PR automatically. This PR is a position
command which absolute position is 0. When E-Cam is not controlling the slave axis, this PR will
take the mechanism back to the origin.
PR#11: Jump to PR#4, restart the capture function and E-Cam function for the actions of the next
cycle.
