5.2 L_CamContactor - cam group with switch-on and switch-off dynamisation
From the cam data under the current product number (specified by the LS_CamInterface SB), this FB
reads the cam track selected via the input dnTrackNumber and outputs the cam status on the spe-
cified position.
• A cam track can contain up to four cams of the same type (path or time cam); however, the cam
type can be different for each product.
• As of Engineer version 2.9 up to 16 cams per cam track are supported.
• By means of a parameterisable dynamic displacement of the cams, deceleration times of swit-
ching elements connected can be compensated.
• If further cam tracks are to be evaluated, further instances of this FB just have to be added to
the application.
