Features
OMNUC AC Servo Drivers control the power supplied to AC Servomotors with pulse-train input signals
and perform precision position control. There are 5 types of AC Servomotors: 100-W, 200-W, 300-W,
400-W, and 750-W.
H
Motor Output Capacity
AC Servomotors with the following output capacities are available.
j
For 200/230-VAC (170 to 253 V) single-phase, 50/60-Hz Input
100 W, 200 W, 400 W, and 750 W
j
For 100/115-VAC (85 to 127 V) single-phase, 50/60-Hz Input
100 W, 200 W, and 300 W
Note 1. Each Servomotor is available with or without a brake.
Note 2. Each motor shaft has a straight axis with a key.
H
EC Directives (CE Markings)
AC Servomotor and Servo Drivers that conform to EC low-voltage and EMC directives are now
available. These provide the same performance and functions as the rest of the U Series UE Mod-
els, and will aid in obtaining specifications.
H
Control Functions
Controls the position and speed of the Servomotor very precisely with pulse-train input signals. Any
one of the following 3 pulse trains can be selected: forward/reverse pulses, feed pulses/directional
signals, or 90
differential phase (A/B phases) signals.
H
Auto-tuning
The gain can be adjusted automatically when the responsiveness has been selected to match the
rigidity of the mechanical system. The auto-tuning feature automatically finds the optimum adjust-
ment to match the load, with no need for difficult operations.
H
Monitor
Displays the driver’s operating status on the Parameter Unit.
The following items can be monitored: speed feedback, torque commands, number of pulses from
the U-phase edge, electrical angle, internal status (bit display), command pulse’s speed, position
deviation, and the input pulse counter.
H
Jog Operation
Forward/Reverse motor operation can be controlled from the Parameter Unit.
