Handle coasting can be prevented by #6677 (handle
lag pulse clamp capacity). With this parameter
installed, when handle is turned
there will
be a gap between quality of handle turning and that
of movement.
Handle coasting can be prevented by #6676 (handle
input pulse clamp capacity). The following describes
an example of this parameter setting.
When #6677 is used as “handle lag pulse clamp
a fraction is obtained in values at the lower
1st/2nd digits even by motion in the handle 10-
time/ 100-times mode. To avoid this, set
= O. Then verify the value of

the value of a obtained by omitting under the decimal
point, which is set to #6676. The setting range of
#6676 is O to 127. When #6676 = O, lag pulse clamp
is not executed. The above input pulses are disre-
garded. Therefore, the maximum distance of the
flowrate is as shown below, affected by the relation to
the handle feeding acceleration/deceleration.

Move command value accumulated internally when handle input
enters in a step.
This value is discharged as remaining
amount after the
handle input is interrupted.
This is equivalent to the JOG button, corresponding to decelera-
tion to a stop after the command is turned off.
