Chapter III System Functions
) Preset drive
“Preset drive” means pulses of a set number are output with a fixed velocity or acceleration/deceleration. This
function is performed when the tool needs to move to a specific position or execute a specific action. The
mechanism of preset drive for acceleration/deceleration is shown in the figure below. When the number of
remaining pulses is smaller than that of accumulated pulses, the system will begin to decelerate, and terminate its
drive once the output of designated pulses is completed.
To perform preset drive for acceleration/deceleration, the following parameters should be set:
a) Range: R;
b) Acceleration/deceleration: A/D;
c) Start velocity: SV;
d) Drive velocity: V;
e) Output pulse number: P
When preset drive for acceleration/deceleration is engaged, the system will start automatic deceleration at the
computed point as shown in the above figure.
