(1) The fixed parameters are set for each axis and their data is fixed in accordance
with the mechanical system or other factors.
(2) The fixed parameters are set with a peripheral device.
(3) The fixed parameters to be set are shown in Table 4.1.

Remarks
Initial Value Units
• Set the command unit in
3
positioning control for each
axis.
• Set the number of feedback
pulses per motor revolution,
20000
PLS
which is determined by the
mechanical system.
• Set the travel value per
motor revolution, which is
PLS
20000
PLS
determined by the
mechanical system.
• Set to change the
magnification for the travel
value per pulse.
• Set the amount of backlash
in the machine.
• Every time the positioning
direction changes during
positioning, compensation
by the backlash
PLS
0

compensation amount is
executed. The expression
below shows the setting
range.

• Set the upper limit for the
machine travel value. The

turned ON [(positioning
address) − (current value)].
