Setting item Setting example Setting details
Da.1 Operation pattern
Positioning
complete
Set "Positioning complete" assuming the next positioning data will not
be executed. ("Continuous path control" cannot be set in "speed-
position switching control (ABS mode)".)
Da.2 Control system
Forward run:
speed/position
Set speed-position switching control by forward run.
Da.3 Acceleration time No. 1
Designate the value set in " Pr.25 Acceleration time 1" as the
acceleration time at start.
Da.4 Deceleration time No. 0
Designate the value set in " Pr.10 Deceleration time 0" as the
deceleration time at deceleration.
Da.5
Axis to be
interpolated
– Setting not required. (Setting value is ignored.)
Da.6
Positioning address/
movement amount 270.00000
degree
ABS mode ( Pr.150 = 2)
Set the address after the switching to position control. (Assuming that
the " Pr.1 Unit setting" is set to "mm".)
Da.7 Arc address – Setting not required. (Setting value is ignored.)
Da.8 Command speed 6000.00mm/min Set the speed to be controlled.
Da.9 Dwell time 500ms
Set a time from the positioning stop (pulse output stop) by position
control until the positioning complete signal is output. When the
system is stopped by speed control, ignore the setting value.
