7.2.2 Manual switchover of the basic system
General
The dimension system for the whole machine is changed using an HMI softkey "Switch to
mm > inch" or "Switch to inch > mm" located in the "POSITION" → "Settings" area. The
softkey can only be accessed in JOG or MDA mode. The switchover is only accepted if:
● The channel is in reset status
● The axes are not being traversed.
Actions such as NC start or mode change are disabled for the duration of the changeover.
