5.6.5 cod 09 (CHK): Servo end check
c
CHECK
By this instruction, the machine performs the servo end check
at the end point of interpolation operation, then moves to the
next operation.
When pulses accumulated in the servo amplifier become the
specified quantity or less, the machine performs the servo end
check in accordance with the positioning completion signal (SV
END) sent from the servo amplifier to the positioning unit.
When the period of time from end of pulse output to input of the
positioning completion signal exceeds the period of time set in
PARA. 21, the positioning unit regards it as a positioning error.
While interpolation operation continues, the machine performs non-stop operation and
inflection points make a smooth curve.
When you would like to move the machine to the target position B or C shown in the figure
on the right, use the cod09 instruction after the cod01 to cod03 instructions in the program.
At the time of shipment, PARA. 21 is set to "0" to disable the servo end check. When you
use the cod09 (CHK) instruction, properly set PARA. 21.
