20. SKIP SIGNALS (INPUT) SKIP
<X000#7, X1000#7>
PMC INTERFACE
213
NOTE
1 The G31 block unconditionally assumes the G01 mode.
The feed rate becomes the value specified by the F code.
2 If measuring using signal SKIP, the feed rate must be
programmed to be constant. Measuring errors become
lange if the feed rate is different. The measuring error when
the feed rate is constant is shown below.
ERRmax : Measuring error [mm or inch]
Fm : Measuring feedrate [mm/min or inch/min]
3 The surpassing amount after signal SKIP rises is shown
below.
Qmax : Surpassing amount [mm or inch]
Fm : Measuring rate [mm/min or inch/min]
Tc : Cutting time constant [msec]
Ts : Servo time constant, normally Ts=33 msec
4 The signal width of signal SKIP must be a minimum of 10
msec.
5 SKIP is read directly by the Power Mate from the machine
side.
6 If not using the skip function (G31), the signal terminal
corresponding to SKIP is available in the PMC as the
general-purpose input signal.
