; -- EXAMPLE OF A PLC PROGRAM FOR A GEAR CHANGE AT THE MAIN SPINDLE --
;
; Information on resources in use:
;
; I41 = Detector for first gear (M41)
; I42 = Detector for second gear (M42)
; I79 = “Drive OK” Spindle Drive
;
; O141 = Electric valve to activate the first gear (M41)
; O142 = Electric valve to activate the second gear (M42)
;
; M41 = Decoding of "M41" from CNC: Change to first gear
; M42 = Decoding of "M42" from CNC: Change to second gear
;
; With parameter PLC P28 (R700) = 3.33172, we define the SERCOS identifier Fagor Diagnostics,
; because in this case, at the spindle, SERCOSID = 3
; B10R700 = SV3. This bit is activated when the spindle speed is lower than the minimum "N" (SP40).
