HG-JR Series This medium/large capacity, low inertia motor is suitable for high-throughput and high-acceleration/deceleration operations.

HG-SR Series This medium capacity, medium inertia servo motor enables stable operation. The industry's shortest length is achieved by optimizing the structural design.

HG-RR Series This medium capacity, ultra-low inertia servo motor is perfect for high-throughput operations

HG-KR / HG-MR Series Rated speed: 3000 r/min Maximum speed: 6000 r/min Maximum torque is 350% of the rated torque, and high torque is achieved during high-speed

MR-J4 Servo Family - Motors

MR-J4 Servo Family - Motors

• Equipped with high-resolution absolute position encoder for increased positioning accuracy

• Improved environmental safety

• Most models are rated IP65 and IP67 for protection from water and dust

• Cable leading direction

• The power encoder and electromagnetic brake cable can be led out in either direction on load side

• Reduced torque ripple during conduction

• By optimizing the combination of the number motor poles and the number of slots, torque ripple during conduction is greatly reduced. Smooth constant-velocity operation of machine is achieved

Linear

• Suitable for direct drive systems requiring high accuracy
• Long-stroke applications are possible
• Core and core-less types are available

Direct Drive

• For compact and simplified machine driving part
• Load is directly coupled with DD motor, so gear and transmission elements can be eliminated
• High resolution encoder contributes high accuracy control

3rd Party motor connectivity

• Control any kind of motor by communication with open encoder protocol EnDAT2.2/Hyperface DSL

Special Motors

High-response capability with SSCNET III/H

Industry leading cycle times as fast as 0.22 ms (3 x faster than J3)

• Smooth control of machine is possible using high-speed
• serial communication with cycle times of just 0.22 ms.

High performance of machine achieved with synchronized communication

• Complete synchronized communication is achieved with SSCNET III/H, offering technical advantages in machines such as printing and food processing machines that require synchronous accuracy.

• Improved noise immunity with the optical communication
• The fiber-optic cables eliminates noise from power cables or external devices.
• Noise immunity is dramatically improved compared to metal cables.

High-response system achieved with SSCNET III/H

Intelligent functionality

• “One-Touch-tuning” only one touch and the system is tuned perfectly
• Real-time auto tuning sets control parameters automatically
• Advanced suppression of mechanical vibration
• Optimum machine resonance suppression filter
• Fast installation and set-up – no matter what the application

Servo/Motion Solutions

TECHNICAL

SIL3

A safer environment

Mitsubishi Electric’s MR family has become the leading choice for motion applications world wide. Industry leading performance, the SSCNETIII/H motion network, and patented technology like vibration suppression has lead to a significant global installed base. Mitsubishi Electric now takes this success one step further by adding safety functions to the MR-J4 line up.

• Accreditation to meet EU Machinery Directive (2006/42/EC)

• Built-in comprehensive safety function

• Safe Torque Off (STO) as standard

• SS1 (Safe stop 1), SBC (Safe brake control), SLS (Safely-limited speed), SSM (Safe speed monitor) can be acheived with option functional safety unit MR-D30 which plugs onto the side of the amplifier.
