2.2.5.4 Examples
Example of the extension of predefined auxiliary functions
For the second spindle of the channel, the auxiliary functions M3, M4 and M5 should be
parameterized:
Parameterization: M3
• Machine data index: 0 (1. user-defined auxiliary function)
• auxiliary function group: 5
• Type and value: M3 (spindle right)
• Address extension: 2 as appropriate for the 2nd spindle of the channel
• Output behavior:
– Output duration one OB1 cycle (normal acknowledgment)
– Output prior to motion
Machine data Machine data index Value
MD22000 $MC_AUXFU_ASSIGN_GROUP 0 5
MD22010 $MC_AUXFU_ASSIGN_TYPE 0 "M"
MD22020 $MC_AUXFU_ASSIGN_EXTENSION 0 2
MD22030 $MC_AUXFU_ASSIGN_VALUE 0 3
MD22035 $MC_AUXFU_ASSIGN_SPEC 0 H21
Parameterization: M4
• Machine data index: 1 (2. user-defined auxiliary function)
• auxiliary function group: 5
• Type and value: M4 (spindle left)
• Address extension: 2 as appropriate for the 2nd spindle of the channel
• Output behavior:
– Output duration one OB1 cycle (normal acknowledgment)
– Spindle response following acknowledgment
– Output during motion
