High Speed and High Precision

Industry Top-class Tracking Performance

Speed Response Frequency of 2 kHz

Speed response is representative of servo system characteristics. In the OMNUC G5, the industry’s fastest response has been achieved at 2 kHz. By improving the speed response by twice compared to previous OMRON models, the stabilization time has been shortened and this contributes to tact time reduction.

Data Updating Cycle of 250µm (EtherCAT models)

EtherCAT communication model is newly added to the OMNUC G5 Series Servo Drives. The data updating cycle is shortened to 250µs, which is 4 times faster than previous OMRON models.

Motion control accurately follows commands. Effective for simultaneous control as well as improving tact time.

* Combination of R88D-KT02H Servo Drive and R88M-K20030H Servomotor. Example of actual measurements taken with gain adjusted by CX-Drive with inertia ratio of x1.

Reduced Tact Time with Higher Speed
Maximum rotation speed for Servo Motors : 6,000 r/min*

The maximum rotation speed of R88M-series Servomotors has increased to 6,000 r/min, resulting in high-speed positioning that can reduce tact time.

* Applicable to 100 V/200 V models with 750 W or less.

Best Positioning Accuracy
Featuring a 20-bit high-resolution incremental encoder

High-precision positioning can be achieved with the built-in encoder, 8 times the resolution of previous OMRON models at 20 bits.

High-precision Positioning
Fully Closed Loop Control Is a Standard Feature

High-precision and high-response positioning can be realized without being affected by temperature changes by determining the position using direct feedback of the control position from the external scale, to enable using fully closed loop control without options. (The external scale connector terminal is a standard feature.)

High-speed and High-precision Positioning
Pulse input response frequency: 4 Mpps

The Servo Drive response to command pulses is 4 Mpps, twice that of previous OMRON models. Response delays are thus reduced enabling high-speed and high-precision positioning.

Ideal for Applications That Require High Accuracy
Improved vibration control function

With the vibration control function, if the tip of the device is vibrating, the vibration frequency can be set to remove the vibration. It can also be used to suppress vibration resulting from starting and stopping the device, allowing precise movement.

Safety

Conforms to the Latest International Standards
Safety and Productivity

The OMNUC G5 was the first to acquire international standard IEC 61800-5-2 (STO) for motion control in the industry within Japan. It also conforms to the European Directives ISO 13849-1: 2006 (PLc,d) and EN 61508 (SIL2). Safety control circuits can be constructed with the Servo Drive, delivering both safety and productivity.

Reduced TCO

Complete Support from Setup to Maintenance

CX-Drive Support Tool

The CX-Drive software allows you to set, transfer, and compare Servo Drive parameters, to perform trial operation and adjustments, and to monitor and trace operation.

Simple Gain Adjustment - Quickly adjust the gain using a wizard

The autotuning feature provided with the CX-Drive makes it easy to adjust the Servo Drive gain. You can use a wizard to complete gain adjustment in approximately five minutes or less per axis simply by selecting the machine configuration and entering the target set time.

One Workflow from Position Control Unit to Network and Servo Drives
 

Just connect the computer to a PLC port to set up the Position Control Units with EtherCAT interface and EtherCAT communications.

You can also directly connect the CX-Drive Support Software to set the Servo Drives connected to the Position Control Units.
