Lead or delay time in setting data
The second lead or delay time is entered into the following general setting data:
● SD41520 SW_CAM_MINUS_TIME_TAB_1[n]
● SD41521 SW_CAM_PLUS_TIME_TAB_1[n]
● SD41522 SW_CAM_MINUS_TIME_TAB_2[n]
● SD41523 SW_CAM_PLUS_TIME_TAB_2[n]
● SD41524 SW_CAM_MINUS_TIME_TAB_3[n]

Activating

The status of the cam (cam signals) can be output to the PLC as well as to the NCK I/Os.
Activation of cam signal output
The output of cam signals of an axis is activated via the NC/PLC interface signal:
DB31, ... DBX2.0 (cam activation)
Check-back signal to PLC
The successful activation of all cams of an axis is signaled back to the PLC using the following
NC/PLC interface signal:
DB31, ... DBX62.0 (cams active)
