2.4 Cs Contour Control
The machine loses its current position when the serial spindle is switched
from spindle rotation control to Cs contour control.
Setting the Cs axis coordinate setup request signal CSFI <G274#4> to ’1’
enables the machine to set up its current position without making a
reference position return.
NOTE
This function stays in effect until the power is turned off after
the power is turned on and a reference position return of the
Cs contour axis is made.
This function is part of the ”Cs axis contour control function.”
This function is put in effect by setting the CSF parameter (bit 2 of
parameter No. 3712) and the CSPTRE parameter (bit 5 of parameter No.
4353) to 1.
(Using this function requires resetting the RFCHK3 parameter (bit 7 of
parameter No. 4016) to 0.)
The M code for setting the Cs axis contour control coordinate setup
request signal CSFI <G274#4> to ’1’ should be set up as buffer inhibit
M codes (parameter Nos. 3411 to 3432).
(1)Trigger the M code to put the machine in the Cs contour control mode.
(2)Make sure that the Cs axis origin setup state signal CSPENA is ’1’,
and set the Cs axis coordinate setup request signal CSFI1 <G274#4>
to ’1’.
(3)The absolute, relative, and machine coordinates of the Cs axis are
incremented for coordinate system setup.
(4)Once the coordinate system is set up, the reference position setup
signal ZRFx <F120#0 to F120#3> becomes ’1’. So, reset the Cs axis
coordinate setup request signal CSFI1 <G274#4> to ’0’.
(5)Perform FIN processing for the M code.
If an attempt to set up Cs axis coordinates fails, the P/S alarm 5346 is
issued.
Also, the Cs axis coordinate setup alarm signal CSFO1 <F274#4>
becomes ’1’. So, reset the Cs axis coordinate setup request signal CSFI1
<G274#4> to ’0’.
Resetting the Cs axis coordinate setup request signal CSFI1 <G274#4>
to ’0’ causes the Cs axis coordinate setup alarm signal CSFO1 <F274#4>
to be reset to ’0’.
