Features

With their superior performance and fast response, plus a wider selection of models, the OMNUC W-se-
ries AC Servomotors and Servo Drivers inherit the features of and surpass the previous OMNUC U Se-
ries.
H Faster Response and Rotation Speed
The W-series AC Servomotors and Servo Drivers provide faster response than the previous U-se-
ries models, with high-frequency responses of 400 Hz (compared to 250 Hz for the U Series). More-
over, the 3,000-r/min Servomotors provide rotation speeds of up to 5,000 r/min, as compared to
4,500 r/min for the U Series, for even faster positioning.
H Wider Selection
In addition to 3,000-r/min (30-W to 5-kW) Servomotors, the W-series product line offers 1,000-r/min
(300-to 5.5-kW) 1,500-r/min (450W to 15-KW), and 6,000--r/min (1.0--to 4.0--kW) models to choose
from. And included among the 3,000-r/min models are Flat-style (100-W to 1.5-kW) Servomotors
that are ideal for applications requiring installation in tight spaces.
H IP67 (Waterproof) Servomotors
The1,500--r/min, 3,000-r/min and 6,000--r/min Servomotors have an enclosure rating of IP67 (wa-
terproof, except for through-shaft parts). And these models, as well as the 3,000-r/min (100 W to
1.5-kW) Flat-style Servomotors, are also available with IP67 enclosure ratings that include water-
proofing for through-shaft parts. Thus the W-series Servomotors can be used even in places where
they may be exposed to water. (The standard cables, however, cannot be used with IP67 models,
and the appropriate cables must be provided by the user.)
H Conformity to Standards
The W Series conforms to EC Directives (both low-voltage and EMC) as well as to UL and cUL,
thereby assisting the user in meeting required standards.
H Built-in Regenerative Power Processing
In addition to the built-in regenerative power processing function using regeneration resistance, ex-
ternal regeneration resistance can also be connected, allowing the W Series to be used for applica-
tions with high regenerative energy on vertical axis.
H Harmonic Current Control Measures
Terminals for DC Reactor connections are provided to assist with harmonic current control.
H Online Autotuning
Autotuning is possible during normal operation with no need to switch to a special autotuning mode,
making it easy to set the gain correctly.
