9.4 Grouping of auxiliary functions

9.4 Grouping of auxiliary functions
Functionality
The auxiliary functions of the types M, H, D, T, and S that are to be issued can be grouped to
auxiliary function groups by means of machine data.
An auxiliary function can only be assigned to one group.
Only one auxiliary function of a group can be programmed per block. Otherwise, alarm
14760 is issued.
Configuration
You can define a maximum of 64 auxiliary function groups. A maximum of 64 auxiliary
functions can be assigned to these 64 auxiliary function groups. This number does not
include auxiliary functions (group 1 to 3) that are pre-assigned as standard.
The actual number of auxiliary functions that are to be assigned must be entered in the NCK-
specific MD11100 AUXFU_MAXNUM_GROUP_ASSIGN (number of the auxiliary functions
distributed to the AUXFU groups). To do so, the password for protection level 2 must be set.
Then, the control must be turned off and on again. Now, the subsequent machine data with
an index n greater than zero are available and additional values can be entered.
An allocated auxiliary function is defined in the following machine data:
● MD22000 AUXFU_ASSIGN_GROUP[n] (auxiliary function group)
● MD22010 AUXFU_ASSIGN_TYPE[n] (auxiliary function type)
● MD22020 AUXFU_ASSIGN_EXTENSION[n] (auxiliary function extension)
● MD22030 AUXFU_ASSIGN_VALUE[n] (auxiliary function value)
Predefined auxiliary function groups
Group 1:
The auxiliary functions M0, M1, and M2 (M17, M30) are, by default, allocated to group 1. The
output is always made at the end of the block.
Group 2:
The M functions M3, M4, and M5 (M70) are, by default, allocated to group 2. The output is
always made before the movement.
Group 3:
The S function is, by default, contained in group 3. The output is made with the movement.
User-defined groups
The other (user-defined) groups are issued with the movement. A different setting of the
outputs can only be set with the "Expert mode" access (protection level 1).
