Note 1: The system exactly stop a block when P, X, U are not input or P, X , U specify negative values.
Note 2: X, U can command the negative value. The absolute value is taken as dwell time in G04, but the
address P cannot command the negative value.
Note 3: P time unit is set by No. 1015 Bit 7(DWT).
Note 4: P, X, U are in the same block, P is valid; X, U are in the same block, the later specified command is
valid.
Note 5: The dwell can be executed after the current delay time is completed in executing the feed hold in
G04.
Note 6: When G04 and subprogram M98 /M99 P__ are in the same block, the number following P is the time
value of G04 dwell, and is also the message of M98/M99, i.e. subprogram skip message error.
Note 7: G04 and the interpolation command in Group 1(such as G00, G01) are in the same block, G04 is
valid, G0, G01 only change the modal value of G commands in Group 1.
Note 8: When No.3403 Bit 6(AD2) is 0, G04 and G commands in Group 00 are in the same block, and the
later specified command is valid.
2.6 Cylindrical Interpolation 7.1
Command function: the cylindrical interpolation is defined that the movement amount of
rotary axis specified by angle is converted into the movement distance
of linear axis along the surface in the CNC inside, which makes the
rotary axis and other axis execute the linear interpolation or circular
interpolation. After interpolation, the distance is converted into the
movement amount of the rotary axis, which is shown below:
