Channel gaps
Channels to which a mode group is assigned with machine data:
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP
are regarded as activated.
Instead of a mode group number, the number "0" can be assigned to channels.
This has the following results:
The nonactivated channel does not take up memory space in the control.
Series machines with similar designs can be kept uniform during configuration. Only the
channels that can actually be used by the machine tool are activated (channels with
mode group number greater than 0).
Special case:
Channel 1 must always be available. If:
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP [0] = 0
is specified, the following is automatically set by the control:
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP [0] = 1 (BAG 1).
Example of configurations:
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[0] = 1
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[1] = 2
...
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[3] = 0 ; gap
...
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[8] = 1
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[9] = 2
