Machine performance can be substantially improved with MR-J3

System's fast response and reliability are realized with SSCNET III

Easy servo adjustment for machine's maximum performance with the high control function and ever-evolving tuning function

For satisfying machine needs, a wide variety of servo amplifiers are available in addition to MR-J3-A with pulse train interface and MR-J3-B with SSCNET III compatible

Conformity with global standards

SSCNET# compatible 2-axis servo amplifier: MR-J3W-B servo amplifier has MR-J3-B servo amplifier’s high performance, functionality and usability. One unit of MR-J3W-B operates any combination of two rotary/linear servo motors or direct drive motors.

Space-saving and reduced wiring: With the MR-J3W-B servo amplifier, two units of motors are operated by one unit of servo amplifier. Thus, mounting area of the servo amplifier can be smaller than ever.

Contributes to energy saving: Two motors are operated by a common power supply. Thus, the regenerative energy can be effectively used.

Common parameters with MR-J3-B: MR-J3W-B servo amplifier uses many of MR-J3-B(-RJ004)’s parameters. Replacement of MR-J3-B is easy. (Different parameters are partially used.)

48 V DC and 24 V DC are available for the main circuit power supply

The 2-axis integrated type reduces wiring and saves space

Compatible with the high-speed optical network SSCNET III. The functions equivalent to those of MR-J3-B are achieved.

Wide range of products: Motor capacities varying from 50W to 55kW with ultra-low to medium inertia are available for various applications. Low-inertia and high-speed HF-JP servo motor series is now also available in medium to large capacities.

Improved environmental safety: HF-KP/HF-MP/HC-LP/HC-RP/HC-UP servo motors are rated IP65 (excluding the shaft-through portion). HF-SP/HF-JP servo motors are rated IP67 (excluding the shaft-through portion).

Low inertia, medium capacity servo motor (0.5kW to 9kW) Max. speed: 6000r/min (rated speed: 3000r/min)✽ This motor is suitable for frequent positioning and acceleration/deceleration operations, and optimal for food packaging and printing machines.

Low inertia, large capacity fan-less servo motor (11kW, 15kW) Max. speed: 3000r/min (rated speed: 1500r/min) Compact size is realized by removing a cooling fan, and wiring is reduced by adopting a power supply connector (reduction by approximately 46% in volume and 34% in mass as compared to HA-LP series). This motor is suitable for frequent positioning and acceleration/deceleration operations, and optimal for injection molding and large press machines.

Newly released servo motor with electromagnetic brake.

Capacities from 10W to 30W with flange size of 25mm x 25mm are available.

Equipped with 262, 144 pulses/rev (18-bit) high-resolution absolute position encoder.

Weight is lighter by max. approx. 35% compared to prior model for more compact machine.

High-speed and high-accuracy: High-speed operation (2m/s) is now possible with this direct drive system. (Conventional transmission mechanisms typically could not achieve such fast operational speeds.) A fully closed loop control system is realized by using position feedback signals from a load-side encoder such as a linear encoder.

Structuring flexible machine drive part: Direct drive arrangement with the linear servo motor enables compact driving part. The linear servo motor is suitable for long-stroke applications since the motor coil moves along with the motor magnet. By configuring multi-head systems with two motor coils on one motor magnet, non-complex and high-tact machine structures can be realized. In addition, the linear servo motors can be configured in tandem especially in large systems that require highly accurate synchronous operation between two axes.

The thrust to volume ratio is increased, allowing space-savings.

High-rigidity is achieved due to the magnetic attraction force functions as a preload on the linear guide.

Speed fluctuations are very small due to elimination of magnetic attraction force and cogging.

The structure with no magnetic attraction force extends life of the linear guides and contributes to lowering audible noise.
