MD28085 $MC_MM_LINK_TOA_UNIT
If several channels are set-up, then the following can be set in the machine data:
Assignment of the TO units (tools and orientable tool holders) to the NC channel. One TO unit can be
assigned to several channels.
- OR -
Each NC channel is assigned one TO unit.
Axial machine data for the modulo rotary axes of the swivel data set

Modulo rotary axis programming
= 0 Programmed positions must be in the modulo range, otherwise an alarm is triggered (e.g. 0
to 359.999 degrees).
= 1 When positions are programmed outside of the modulo range, no alarms are signaled. The
position is modulo converted internally (e.g. -180 to +180 degrees).
Positioning, rotary axis
= 0 As programmed
= 1 Along the shortest path
Application: With the setting bit 2=1, the rotary axis C travels along the shortest path for G90
with DC. For further information, refer to Chapter "Manufacturer cycle CUST_800.SPF
(Page 589)".
