OMNUC W-series AC Servo Drivers (R88D-WT
j
)
Referring to
2-2 Servo Driver and Servomotor Combinations
, select a
Servo Driver to match the Servomotor that is being used.
OMNUC W-series AC Servomotor Drivers can handle either pulse in-
puts or analog inputs. The control mode is switched to match the con-
troller being used. (The default setting is for position control by pulse
train commands.)
