Programming Instructions
BEF = AE Modify setpoints
SPDB: KY = x, y 0< x <31 Track number
KB : Output of identifier bits, or
KB1 : Output of identifier bits (High word) -t Channel 2
KB2 : Output of identifier bits (Low word) + Channel 1
ST
: Output of control bits
Both
setpoints must be specified per track.
The track is deleted for interrupt identifier KH = FFFE
BEF = SS Software-based synchronizing
BEF = SH Hardware–based synchronizing
SPDB :
KY = x, y x = 32: Zero shift, Channel 1
x = 33: Zero shift, Channel 2
KB
: Output of identifier bits, or
KB1 : Output of identifier bits (High word) -t Channel 2
KB2 : Output of identifier bits (Low word) -+ Channel 1
ST
: Output of control bits
If BEF=SH, the zero shift values are transferred without an SS bit; this is
the precondition for hardware– based synchronizing with preliminary contact and
zero mark (see operating instructions).
If BEF=SS, the zero shift values are transferred with an SS bit; this
ac–
complishes software– based synchronization of the counter.
