(1) Turning ON the "F1 DIGIT FEED" switch enables the feedrate to be increased/decreased by
turning the handle when the feedrate in the program is an F1 digit.
(2) The increase/decrease amount per handle gradient is expressed with the following equation.
(Example) For a 10mm/min. increase/decrease amount per handle gradient:
(3) The conditions for validation are as follows:
(a) The operation must be automatic (program run, MDI).
(b) The operation must be in automatic start.
(c) The operation must be in cutting feed, and F1 digit feedrate command must be issued.
