Fig. 7-6 Mode management outputs
The mode management outputs become the control signals for the
position ramp function generator and the correction block.
Binector B0870 ENABLE_POS_REF = 1 enables the series-connected
function blocks (positioning block, correction block).
Binector B0877 PSR (POS/SETUP/REF) shows that one of the three
modes POS, REF or SETUP is active.
Binector B0893 REF_DRIVE = 1 shows that "homing movement" with
reversing cams is active.
Binector B0895 SET_REF_D = 1 shows the preferred direction REF_D
(input Src U866.14).
