Function
The control system can operate with the inch or the metric system of
measurement. You can switch between the inch and metric
measuring systems in the "Machine" operating area. The control
converts the values accordingly.
The switchover is only possible if:
• The corresponding machine data have been set.
• All channels are in the Reset state.
• Axes are not traversing with JOG, DRF or PLC control.
• Constant grinding wheel peripheral speed (GWPS) is not active.
The display resolution for the inch system of measurement is defined
by machine data.
Actions such as parts program start or mode change are disabled for
the duration of the switchover.
Operating sequence
"AUTO"/"MDA"/"Jog" mode is selected in the "Machine" operating
area.
Press the ETC key followed by
the "Switch mm > inch" softkey.
When the system of measurement is changed, all length-related
parameters are automatically converted to the new system of
measurement from the perspective of the operator.
If the switchover cannot be performed, this is indicated by a message
in the user interface.
