Outline

The 1S-series Servo Drives with Built-in EtherCAT communications support 100-Mbps EtherCAT.
When you use the 1S-series Servo Drive with a Machine Automation Controller NJ/NX-series CPU Unit
or Position Control Unit with EtherCAT (Model: CJ1W-NC8), you can construct a high-speed and
sophisticated positioning control system.
You need only one communications cable to connect the Servo Drive and the Controller. Therefore, you
can realize a position control system easily with reduced wiring effort.
With adjustment functions, adaptive notch filter, notch filter, and damping control, you can set up a sys-
tem that provides stable operation by suppressing vibration in low-rigidity machines.
Moreover, with the two-degree-of-freedom (TDF) control structure, you can easily adjust high-precision
positioning.

Features of 1S-series Servo Drives

The 1S-series Servo Drives have the following features.
Optimal Functionality and Operability by Standardizing Specifica-
tions
As a Sysmac Device, 1S-series Servo Drives with built-in EtherCAT communications is designed to
achieve optimum functionality and ease of operation when it is used together with the NJ/NX-series
Machine Automation Controller and the Sysmac Studio Automation Software.
Sysmac Device is a generic term for OMRON control devices such as an EtherCAT Slave, designed
with unified communications specifications and user interface specifications.
Data Transmission Using EtherCAT Communications
Combining the 1S-series Servo Drive with a Machine Automation Controller NJ/NX-series CPU Unit or
Position Control Unit with EtherCAT (Model: CJ1W-NC8) enables you to exchange all position
information with the controller in high-speed data communications.
Since the various control commands are transmitted via data communications, Servomotor's opera-
tional performance is maximized without being limited by interface specifications such as the response
frequency of the encoder feedback pulses.
You can use the Servo Drive's various control parameters and monitor data on a host controller, and
unify the system data for management.
EtherCAT Communications Cycle of 125 µs
Combination with an NX7 Machine Automation Controller enables high-speed and high-precision
motion control at the communications cycle of 125 µs.
High Equipment Utilization Efficiency with 400-V Models
The 400-V models are provided for use with large equipment, at overseas facilities and in wide-ranging
applications and environment. Since the utilization ratio of facility equipment also increases, the TCO
(Total Cost of Ownership) will come down.
