PLC programming example.
The machine has a button to activate and deactivate this feature (feed handwheel) and the feedrate
control is carried out with the second handwheel.
CY1
R101=0
Resets the register containing the previous handwheel reading.

DFU I71 = CPL M1000
Every time the button is pressed, mark M1000 is inverted.
M1000 = MSG1
If the feature is active, a message is displayed.
NOT M1000
= AND KEYDIS4 $FF800000 KEYDIS4
= JMP L101
If this feature is not active, it enables all the positions of the feedrate override switch and resumes
program execution
DFU M2009
= CNCRD(HANPS,R100,M1)
= SBS R101 R100 R102
= MOV R100 R101
= MLS R102 3 R103
= OR KEYDIS4 $7FFFFF KEYDIS4
If this feature is activated and an upflank occurs at the clock mark M2009, it reads in R100 the
handwheel pulses (HANPS), calculates in R102 the number of pulses received since the last
reading, updates R101 for the next reading, calculates in R103 the value of the right feedrate
and inhibits all the positions of the feedrate override switch (KEYDIS4).
CPS R103 LT 0 = SBS 0 R103 R103
CPS R103 GT 120 = MOV 120 R103
It adjusts the value of R103 (feedrate %). It ignores the handwheel turning direction (sign) and
limits the value to 120%
DFU M2009
= CNCWR(R103,PLCFRO,M1)
With the up flank at the clock mark M2009, set the calculated feedrate override (PLCFRO=R103)
