15.1.10 Selecting the master spindle of a channel
#MASTER Establishes the master spindle of a channel
The master spindle is the main spindle of the channel. It is the spindle
that receives the commands when no specific spindle is mentioned.
The programming format is:
#MASTER <Sn>
If no master spindle is indicated, it assumes one according to the
following criteria. In general, whenever a channel has a single spindle,
it will be its master spindle.
• If the whole system only has one spindle, it will be the master
spindle of the current channel.
• If a spindle is added to a channel that does not have one, it will be
the master spindle.
• If a channel releases its master spindle and it has only one spindle
left, this one will be its new master spindle.
• If a channel having two spindles but no master spindle releases
one of them, the remaining one will be its master spindle.
• At first, in a channel with several spindles, the master spindle will
be the one configured by machine parameters.
• If two or more spindles remain in a channel and none of the
previous rules may be applied, the master spindle must be defined
using the #MASTER instruction.
The same treatment described for adding or removing spindles is
applied for parking and unparking spindles.
On startup, it follows the same criteria to decide which is the master
spindle of the channel. If this spindle is parked, it will assume the next
spindle, if there is one, as master spindle of the channel.
