Servo Motor Drivers
Easy Operation
As with a stepping motor, stable operation can be achieved in high inertia drive and belt mechanism drive applications without gain adjustment using the servo motors. Also, adjusting the gain manually enables operation under even more stringent load conditions.
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 with Belt Mechanisms
Belt mechanisms can be operated with the same performance as a stepping motor without the occurrence of vibration before stopping.
Driver Operation
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.
Easy Setting and Easy Monitoring
By using the control module (OPX-2A) [sold separately] or data setting software (MEXE02) [sold separately], it is possible to perform changing of parameters, function setting and monitoring that is better suited to your system.
4 Control Modes
Position Control
The built-in, high-resolution 20-bit absolute encoder enables highly accurate positioning of the servo motor.
High Speed and High Response
High-speed positioning can be performed utilizing the high-speed and high response characteristics.
Maximum Speed 5500 r/min
Factory Setting Time 60 to 70 ms
Damping Control
Eliminates load resonance by adjusting the potentiometer. This adjustment can be made easily and without searching for the resonance frequency.
<Application Example: Image inspection equipment>
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 servo 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.
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 film can be easily performed without using a tension detector or control equipment using the servo motor.
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 is provided to the control power supply terminal. (Operation with only the main power supply is also possible.)
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.)
NX Series Servo Motors
The NX Series servo motors are capable of highly accurate control with easy operation, similar to stepper motors. These servo motors are specialized for high-response, high-precision positioning. As a motor capable of accurate rotation angle and speed control it can be used for a variety of equipment.

Control Options - Control Module
The internal driver parameter settings and data settings can be established and changed. They can also be used for speed and I/O monitoring, teaching, and so on.
Control Options - Data Setting Software
This communication cable is required for connecting to the computer on which the data setting software is installed.
Battery
This battery is for constructing an absolute system. Position information can be stored during power blackouts or if the driver's power supply is switched OFF.
Regeneration Unit
Sometimes the regenerative power generated by the motor exceeds the driver's regenerative power absorption capacity. In such a case, a regeneration unit is connected to the driver to release the regenerative power.
Conditions under which a regeneration unit may be required; when using for vertical operation, during acceleration and deceleration time when an inertial load is installed.
