Servo Motors - NX Series

NX Series

Tuning-Free Servo Motor & Driver Packages

The NX Series is a motor, driver and gearhead solution, offering guaranteed performance, in one simple package.

Each package features a high performance servo system capable of high accuracy control. Smooth operation can be achieved in high inertia loads or belt drive applications without manual tuning. Also included are standard 3 meter (9.8 ft.) cables.

Features (Cables Included)

Standard Type	Geared Type	Electromagnetic Brake Type
Max Speed 5,500 r/min 50 ~ 750 Watts	Dedicated high-strength planetary gearhead 50 ~ 750 Watts	Electromagnetic brake model 50 ~ 750 Watts Available with or without planetary gearhead

Easy Operation

As with a stepping motor, stable operation can be achieved in high inertia drive and belt mechanism drive applications without gain adjustment. Also, adjusting the gain manually enables operation under even more stringent load conditions.

Easy Handling

Basic settings and adjustments are made with switches and potentiometers on the front panel. This design allows for easy control without a computer and even saves the hassle of complicated UP and DOWN key operations.

NX Servo Motors

Achieves High Inertia Drive

With automatic tuning, operation up to 50 times the rotor inertia is possible. With manual tuning, operation up to 100 times the rotor inertia is possible

Achieves Smooth Operation

Achieves Smooth Operation with Belt Mechanisms. Belt Mechanisms can be operated with the same feel as a stepping motor, including operation without vibration before stopping is possible.

NX Series

Easy Setting & Easy Monitoring

By using the separately sold control module (OPX-2A) or data setting software (MEXE02), it is possible to perform changing of parameters, function setting, and monitoring that is better suited to your system.

NX Series Wave Form

High Performance Geared Motors

High Permissible Torque and Wide Permissible Speed Range

The NX Series features geared motors with high permissible torque that fully utilize the motor output torque. Each motor and gearhead comes pre-assembled so installation is easy.

PS Geared Type

PS geared motors with a new planetary gear mechanism are available.

Low Backlash The backlash is 15 arc minutes max. These motors can be used in wide-ranging applications.

Available in 50 W, 100 W, 200 W and 400 W

Available gear ratios: 5:1, 10:1, 25:1

PJ Geared Type

Non-Backlash Geared motors that use high accuracy gears with an angular transmission accuracy of 4 arc minutes and backlash of 3 arc minutes.

Surface Installation is Possible There are screw holes that permit installation of a load directly on the rotating surface integrated with the shaft. Since the load can be installed here directly (surface installation), the design is simple when using an index table.

Available in 750 W

Available gear ratios: 5:1, 10:1, 25:1

Four Control Modes

This servo unit can operate in four control modes: position control, speed control, torque control and tension control. Also, with the separately sold control module (OPX-2A) or data setting software (MEXE02), the functions of each control mode can be extended.

I. Position Control

The built-in high-resolution 20-bit absolute encoder enables highly accurate positioning.

- HIgh Speed & High Response

High-speed positioning can be performed utilizing the high-speed
and high-response characteristics.

NX High Speed

- Damping Control

Eliminates load resonance by adjusting the potentiometer. This
adjustment can be made easily and without any bothersome
work such as searching for the resonance frequency.

<Application Example: Image inspection equipment>
Camera vibration during stopping can be suppressed by using
the damping control.

NX Application Example

- Absolute System
Use as an absolute system by attaching an optional battery (sold separately) is possible. The current position of the encoder can be stored, so resetting after a blackout or similar occurrence is easy.

II. Speed Control

The reduction of motor cogging torque and the use of a high resolution encoder have substantially reduced variation in rotation in the low-speed range (the flutter characteristic), resulting in smooth operation even at low speeds.

Speed Control

III. Torque Control

Variation of the generated torque relative to the set torque (torque accuracy) has been improved, resulting in highly accurate torque control.

NX Torque Control

IV. Tension Control

Tension control such as winding films can be easily performed without using a detector or control equipment.

Tension Control

Additional Features

Degree of Protection: IP65

These motors conform to IP65 and they are ideal for use in environments requiring dust resistance and water resistance to protect against cutting dust suspended in air, splashed water droplets, etc. (Standard type, electromagnetic brake type, PS geared type: excluding installation surface and connector locations, PJ geared type: excluding connector locations)

Separate Main Power Supply and Control Power Supply

A control power supply terminal that is separate from the main
power supply is provided. Even when the main power supply
is cut off in the case of, for example, an emergency stop,
operations such as position detection and alarm contents
checking can be performed if 24 VDC power is supplied to the
control power supply terminal. (Operation with only the main
power supply is also possible.)

Simple Connections with Included Cable

The NX Series comes with a 3 m cable to connect the motor and
driver. Shorter or longer cables (1m - 20m) are sold separately both standard and flexible.

Cables

Conforms to Semiconductor Equipment and Materials
International Standards "SEMI F47"

- Conforms to SEMI Standards regarding power supply voltage drop.

- Effective for use in semiconductor equipment. (Always evaluate the product with it mounted on actual equipment.)

Control Module OPX-2A (sold separately)

Functions can be extended and settings shown on a digital display by using a separately sold control module (OPX-2A).

MEXE02 Data Setting Software

MEXE02 Data Setting Software is for use of the extended functions. Allows for changes to parameters, add functions and use waveform monitoring to confirm the operation with a computer.
