● Offset
The time displacement of the position-time cam is calculated by adding together the
associated entries for the cam pair in:
MD10460 SW_CAM_MINUS_LEAD_TIME[n]
SD41520 SW_CAM_MINUS_TIME_TAB_1[n]...
SD41526 SW_CAM_MINUS_TIME_TAB_4[n]
● Mode
MD10485 SW_CAM_MODE
Bit 2 = 1 must be set in the machine data to ensure that all cam pairs with the same values
for minus cam and plus cam positions are treated as position-time cams.
