Auxiliary M, S, T functions
SBCD (R557)
This register will be used when using a spindle operating with BCD coded S signal. spindle
parameter SPDLTYPE (P0).
The auxiliary S function will always be executed at the beginning of the block and the CNC will wait
for the general logic input AUXEND to be activated to consider the execution completed.
If S output in 2-digit BCD is used the CNC will tell the PLC, by means of this register the selected
spindle speed according to the following conversion table:
If a value over 9999 is programmed the CNC will tell the PLC the spindle speed corresponding to
value 9999.
If S output in 8-digit BCD is used the CNC will indicate the programmed spindle speed to the PLC
by means of this register.
This value will be coded in BCD format (8 digits) in thousandths of a revolution per minute.
If no S has been programmed in the block, the CNC will assign a value of $FFFFFFFF to this
register.
