12 CONTROL SUB FUNCTIONS
[3] Control Precautions
It is recommended that the "movement amount per pulse (A)" be set to a value
close to "1" for the following reasons. The "movement amount per pulse" of "1"
means the minimum value in each "
Pr.1 Unit setting". (0.1 [
μ
m] for the unit
[mm])
(1) When the setting of the movement amount per pulse is decreased, the
command frequency may increase. Be careful when changing the setting.
(2) If the setting of the movement amount per pulse is less than 1, the
mechanical system may oscillate. Be sure to use the movement amount per
pulse among the range indicated below.
Movement amount per pulse (A) >
1
500
If the mechanical system oscillates, also use the electronic gear function of
the drive unit and the movement amount per pulse greater.
(3) Set the movement amount per pulse so that the pulse output frequency for
the drive unit becomes a value in the following table.
QD75P N/QD75P QD75D N QD75D
Pulse output frequency
for drive unit
200kpulse/s or less
4Mpulse/s or less
1Mpulse/s or less
If the setting of pulse output frequency for the drive unit exceeds a value in
the table, the QD75 may not operate correctly.
REMARK
In the QD75, the general term for the functions in this section is defined as the
"electronic gear function". Refer to the User's Manual for the servomotor for the
definition of the "electronic gear" on the servomotor side.
