Precautions
(1) The "high-accuracy control" specifications are required to use this function.
If G61.1 is commanded when there are no specifications, a program error (P123) will occur.
(2) Command G61.1 in an independent block.
(3) The G61.1 command can be used when the basic parameter "#1267 ext03/bit0" is set to "0". If
G61.1 is commanded when the parameter is set to "1", a program error (P34) will occur.
(4) This function may not be usable depending on the model.
(5) The #1205 G0bdcc (G0 pre-interpolation) can be used with only one part system.
If the 2nd or later part system is set to the G0 acceleration/deceleration before interpolation, an
error will occur.
(6) "#1568 SfiltG1", "#1569 SfiltG0" and "#1570 Sfilt2" cannot be changed from the screen during
program operation. If these parameters is changed by "parameter input by program", these
parameters are valid after the axes stop.
