1.6 Rapid Traverse Override Input Signal
The rapid traverse override input signal determines the rapid traverse rate used in the execution
of positioning in automatic operation of CNC program, and also for manual rapid traverse
operation with the RT input “closed”.
IMPORTANT!
ROV4 can only be used when the extension override function (option) is selected.
Input Signals and Rapid Traverse Rates
Note 1: The status of signals is indicated by “0” or “1”.
0: Open
1: Closed
Note 2: Interpretation of the value set for ppm 2447, used for determining the traverse rate F
0
is indicated below.
pm2000 D3=0: The units of the value set forpm2447 are “mm/min.”.
pm2000 D3=1: The units of the value set forpm2447 are “%”.
