Execution channels
NEXT
The order of the axes in the channel sets the main work planes, those selected with functions
G17, G18 and G19. At the lathe model, parameter GEOCONFIG also affects when setting
the main work planes.
Allowing to change channel axes and spindles.
The configuration of a channel may be modified via part-program or MDI, either adding or
removing axes as well as spindles. Doing this requires defining for each axis and spindle
whether it may change channels or not and whether the change is permanent or not.
When the changes in the channel are permanent, the original configuration (the one defined
in the machine parameters) may be restored either by validating the machine parameters
or by undoing the changes, for example using a part-program. It must be borne in mind that
validating the machine parameters restores the configuration of all the channels.
Parameter. Meaning.
AXISEXCH Channel change permission.
Arithmetic parameter configuration.
The CNC has three types of arithmetic parameters, namely local, global and common.
Local arithmetic parameters.
Local parameters may only be accessed from the program or subroutine where they have
been programmed. There are seven groups or levels of local parameters in each channel.
The maximum range of local parameters is P0 to P99, the typical range being P0 to P25.
When the parameters are used in the block calling a subroutine may also be referred to by
the letters A-Z (except Ñ) so "A" is the same as P0 and "Z" the same as P25.
Parameter. Meaning.
MAXLOCP Maximum local arithmetic parameter.
MINLOCP Minimum local arithmetic parameter.
Global arithmetic parameters.
Global parameters may be accessed from any program or subroutine of the channel. There
is a group of global parameters in each channel. The maximum range of global parameters
is P100 to P9999, the typical range being P100 to P299.
Parameter. Meaning.
MAXGLBP Maximum global arithmetic parameter.
MINGLBP Minimum global arithmetic parameter.
Common arithmetic parameters.
The common parameters may be accessed from any channel. The value of these parameters
is shared by all the channels. The maximum range of common parameters is P10000 to
P19999, the typical range being P10000 to P10999.
Parameter. Meaning.
MAXCOMP Maximum common arithmetic parameter.
MINCOMP Minimum common arithmetic parameter.
Channel operation and display.
The way to access the different channels is handled through the change key. This key may
be configured either to access the channels sequentially or to show the list of available
channels on the softkey menu.
