AC Servo Motors
Tuning-Free AC Servo Motor Unit

NX Series

4 Control Modes

This servo unit can operate in 4 control modes.
Also, with the separately sold control module (OPX-2A) or data setting software (MEXE02), the functions of each control mode can be extended.

Position Control

The built-in high-resolution 20-bit absolute encoder enables highly accurate positioning.
● High Speed and High Response
High-speed positioning can be performed utilizing the high-speed and high-response characteristics.

● 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.

Camera vibration during stopping can be suppressed by using the damping control.

● 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.

Speed Control

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

Torque Control

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

Tension Control

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