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-W to 5.5-kW) models and 1,500-r/min (450-W to 15-kW) models to choose from. They are
ideal for applications requiring high torque. 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
The 3,000-r/min (1- to 5-kW), 1,000 r/min (300 W to 5.5 kW), and 1,500 r/min (450 W to 15 kW)
Servomotors have an enclosure rating of IP67 (waterproof, except for through-shaft parts). The
3,000-r/min (100 W to 1.5-kW) Flat-style Servomotors are also available with IP67 enclosure rat-
ings that include waterproofing for through-shaft parts. Therefore, the W-series Servomotors can
be used even in places where they may be exposed to water. (The standard cables, however, can-
not 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.
