A. Check that the system is ready to start normal operation.
B. Prepare and check the ladder program for the Cs contouring control
B. function. (Refer to the Descriptions (B–65162E).)
C. Set the necessary parameters for Cs contouring control.
(See Section 2.5.3.)
D. Check and adjust the waveforms on the Cs contouring control detector.
E. Check the operation of reference position return.
D Direction of return to the reference position in Cs contouring control mode
D Maximum speed in Cs contouring control mode
D Feedrate at which return to the reference position is performed in Cs
contouring control mode
D Parameter for the rate of change in the position gain for return to the
reference position in Cs contouring control mode
F. Check the stop position when return to the reference position is performed.
D Grid shift in Cs contouring control mode
G. Check the direction of spindle rotation in Cs contouring control mode.
D Parameter specifying the direction of rotation for a positive (+) motion
command
H. Adjust and check the Cs contouring control servo system.
(Check the operation in jog mode, rapid feed mode, handle mode, and
other modes.)
