22.1.10 Modifying the configuration of the spindles of a channel
The CNC can have up to four spindles distributed between the various channels of the
system. A channel may have one, several or no spindles associated with it.
Initially, each channel has some spindles assigned to it as set by the machine parameters.
While executing a program, a channel may release its spindles or request new spindles. This
possibility is determined by machine parameter
AXISEXCH
, which establishes whether a
spindle can change channels or whether this change is permanent or not.
A permanent change is maintained after the end of the program, after a reset and on power-
up. The original configuration may be restored either by validating the general parameters
and restarting or by a part-program that undoes the changes.
Knowing if a spindle can change channels
Machine parameter
AXISEXCH
may be consulted using the following variable.
V.MPA.AXISEXCH.Sn
Replace "Sn" with the spindle name.
Knowing in which channel the spindle is
It is possible to know in which channel the spindle is by using the following variable.
V.[n].A.ACTCH.Sn
Replace "Sn" with the spindle name.
Replace the "n" letter with the channel number.
Commands for modifying the spindle configuration via program
The following instructions are used to modify the configuration of the spindles of the channel.
It is possible to add or remove spindles, change the name of the spindles and define which
one is the master spindle of the channel.
#FREE SP
Frees a spindle from the configuration
Removes the defined spindles from the current configuration.
The programming format is as follows:
#FREE SP [<Sn>,...]
#FREE SP ALL
It also restores the machine parameter settings if a checksum error occurs when powering up the CNC. .
Value Meaning
0 It cannot change channels.
1 The change is temporary.
2 The change is permanent.
Value Meaning
0 It is not in any channel.
1-4 Channel number.
Parameter Meaning
<Sn> Spindle name.
ALL Frees all the spindles of the channel.
#FREE SP [S]
(It removes the spindle S from the configuration)
#FREE SP [S1,S4]
(It removes spindles S1 and S4 from the configuration)
#FREE SP ALL
(It removes all the spindles from the configuration)
