3.4 Consultation and modifiable signals associated with the –S–
function.
3.4.1 Consultation signals.
SFUN1···SFUN4
There is a register for each spindle. The mnemonics for each spindle are the following:
SFUN1 SFUN2 SFUN3 SFUN4
These registers indicate the programmed speed for each spindle. These registers refer to
the spindle number; they are independent from the channel where the spindle is. The CNC
only uses the registers of the spindles whose SPDLTIME parameter has a value other than
zero.
Each one of them indicates the value of one of the S functions programmed. If all the registers
are not used, the CNC assigns $FFFFFFFF to the unused ones (those with the highest
numbers).
This way, if a block contains functions S1000 and S1=550 and the value of SPDLTIME
parameter of both spindles is other than zero, the CNC will transfer the following information
to the PLC.
SFUN1 SFUN2 SFUN3 SFUN4
1000 550 $FFFFFFFF $FFFFFFFF
SSTROBE
There is a mark for each spindle. The mnemonics for each spindle are the following:
SSTROBE1 (can also be programmed as SSTROBE)
SSTROBE2 SSTROBE3 SSTROBE4
The CNC channel sets this mark high (=1) to indicate to the PLC that a new spindle speed
has been selected. The CNC channel only uses this mark on spindles whose SPDLTIME
parameter has a value other than zero.
SPN1···SPN7
There is a register for each channel. The mnemonics for each channel are the following. Here
is an example of the mnemonics for SPN1; it is the same for the rest of the registers.
SPN1C1 SPN1C2 SPN1C3 SPN1C4
The channel uses these registers to indicate to the PLC which spindle of the channel each
auxiliary M function selected for execution is addressed to.
Each channel can have up to 7 M functions in a block. If all the registers are not used, the
hexadecimal value $FFFFFFFF is assigned to the unused ones (those with the highest
numbers).
This way, if the next block is programmed in the first channel, the CNC will pass on to the
PLC the following information.
M3.S1 S1=1000 M4.S2 S2=500
Clockwise rotation of spindle S1 at 1000 rpm and counterclockwise rotation of spindle S2
at 500 rpm.
MFUN1C1 MFUN2C1 MFUN3C1 - MFUN7C1
3 4 $FFFFFFFF
SPN1C1 SPN2C1 SPN3C1 - SPN7C1
1 2 $FFFFFFFF
If a function is programmed in the block without mentioning the spindle, it will assume the
master spindle of the channel.
