5.3.1 Special considerations with the multi-spindle option and channels.
The CNC may have up to four spindles. All of them may be controlled independently in the
same block; in other words, each spindle may be given a different command.
When using channels, the spindles may be distributed indistinctly between them. In this
case, a channel can control a spindle of another channel. The marks and registers refer to
the spindle regardless of the channel they belong to.
The spindle number is determined by its logic number that is set by the order they were
defined in the machine parameter SPDLNAME.
Marks and registers in the multi-spindle version.
The CNC indicates to the PLC which S functions are programmed in the execution block
using 32-bit registers SFUN1 through SFUN4. These registers refer to the spindle number;
they are independent from the channel where the spindle is.
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, the CNC will transfer the following
information to the PLC:
Commands SP1FUN* - SP4FUN*. Check if an auxiliary function has been programmed
for a spindle.
Considering the possible channels/spindles combinations, these functions are available to
make it easier to manage the auxiliary M functions associated with each spindle. Each one
indicates if any M3, M4, etc. type M function has been programmed in any channel.
SP1FUN* For the spindle 1.
SP2FUN* For the spindle 2.
SP3FUN* For the spindle 3.
SP4FUN* For the spindle 4.
