3.6.1 Consultation signals.
FREE
There is a mark for each channel. The mnemonics for each channel are the following.
FREEC1 FREEC2 FREEC3 FREEC4
The CNC channel sets this signal high (=1) to indicate to the PLC that it is ready to accept
a new block, sent using the CNCEX command.
WAITOUT
There is a mark for each channel. The mnemonics for each channel are the following.
WAITOUTC1 WAITOUTC2 WAITOUTC3 WAITOUTC4
It is applied to channel synchronization. The CNC channel sets this signal high (=1) to
indicate to the PLC that it is waiting for a synchronization signal. Synchronization signals may
be executed from the part-program using the #WAIT or #MEET instructions.
SYNC
There is a register for each channel. The mnemonics for each channel are the following.
SYNC1 SYNC2 SYNC3 SYNC4
This register is used when using, from one channel, a particular spindle for synchronization
even if the spindle is in another channel. For example, in the case of dual-turret lathe with
a single spindle.
With the G33 function, when threading with a particular spindle.
With the G95 function, when programming the feedrate as a function of the turning speed
of a particular spindle.
To do that, the PLC indicates in channel register SYNC the spindle to be used, only for
synchronization. The SYNC register will take values 1 through 4; when assigning a 0 value,
it will use the master spindle of the channel.
The CNC will check the contents of this register at the beginning of the block. If the PLC
modifies this register during the execution of the block, the change will not effective until the
beginning of the next block.
