Introduction
Chapter 1
1-1 Features
OMNUC W-series AC Servo Drivers with built-in MECHATROLINK-II Communications
are designed specifically for use with the MECHATROLINK-II high-speed motion field
network.
Combining these Servo Drivers with MECHATROLINK-II-compatible Motion Control
Units (CS1W-MCH71 or CJ1W-MCH71) or Position Control Units (CJ1W-NCF71) is an
easy way to create a high-speed servo control system with a communications link
between the Servo Drivers and the Controllers.
■ Data Transfer by MECHATROLINK-II Communications
When a Servo Driver is combined with a MECHATROLINK-II-compatible Motion Control Unit (CS1WMCH71 or CJ1W-MCH71) or Position Control Unit (CJ1W-NCF71), all control data is transferred
between the Servo Driver and the Controller by means of data communications.
Control commands are transferred by means of data communications, so Servomotor performance is
not limited by control interface specifications, such as response frequencies for input pulses and
encoder feedback pulses. This allows the Servomotor to perform to its fullest capacity.
Moreover, system data control is simplified by having all Servo Driver parameters and monitor data
managed by the host controller.
■ Built-in Communications Interface
The MECHATROLINK-II communications interface has been built into the Servo Driver. In comparison with earlier W-series Servo Drivers, in which the MECHATROLINK-II Application Module is
installed, only 60% of the installation surface area is required. (for 200-V/100-W Servo Drivers). This
allows a great saving of space in the control panel.
■ W-series Servomotor Compatibility
A W-series Servomotor can be used as is, including the encoder cable and power cable, so the system can be upgraded without changing the structural design.
The W-series product line offers 3,000-r/min Servomotors (Cylinder-style: 50-W to 3-kW; Flat-style:
100-W to 1.5-kw), 1,000-r/min Servomotors (300-W to 2-kW), and 1,500-r/min Servomotors (450-W
to 1.8-kW). Also, IP67 (waterproof) Servomotors can be connected in the same way.
■ High-speed, High-precision Motion Control Capability
A less-deviation control function and a predictive control function are provided to shorten the Servomotor's settling time and achieving high tracking capability.
The W-series Servomotors handle motion control with increased speed and precision, including synchronous control in combination with CS1W-MCH71 or CJ1W-MCH71 Motion Control Units.

Introduction
■ Regenerative Power Processing
In addition to the built-in regenerative power processing function using regeneration resistance,
external regeneration resistance can also be connected, allowing the W Series to be used for applications with high regenerative energy on vertical axes.
■ Conformity to Standards
The W Series conforms to EC Directives (both low-voltage and EMC) as well as to UL and cUL
requirements, thereby assisting the user in meeting required standards.
■ High-frequency Current Countermeasures
On Servo Drivers of 1 kW and above, a current reactor connection terminal is provided to assist the
user in controlling high-frequency current.

Charge Indicator
Lit when the main-circuit is powered.
Also, for Servo Drivers of 1 kW or less,
the indicator lights dimly when only the
control power supply is ON. Even after
the power is turned OFF, it remains lit
as long as an electric charge remains in
the main-circuit capacitor, so do not
touch the Servo Driver's terminals
during this period.
Main-circuit Power Terminals
These are the input terminals for
the main-circuit power supply.
