Servo Amplifiers

The MR-J2 provides intelligent advanced dynamic performance without the need for complex set-up or programming. Three in one – with a digital interface for position control, an analogue interface for speed and another for torque control, the MR-J2 can easily be retro-fitted into existing applications or used to design revolutionary new control systems for new machines. Other major features include:

RS 232C Serial communications interface – allows a Windows based programming package to read/write and store parameters together with extensive monitoring and diagnostic functions. (RS 485 option also available).

Absolute positioning system – all motors in this range are fitted with absolute encoders backed by a battery in the amplifier to eliminate the need to re-home on power down and so reduce production time.

Servo-lock anti-vibration function – this function eliminates the encoder bounce that is often associated with brushless servo systems.

Built-in dynamic brake and regenerative resistor – the servo motor can be stopped immediately in the event of a power failure without the need for an external regeneration unit.

Compatible – with all of MR-J2 range motors

There are different types of amplifiers for different purposes:

The MR-J2S-A range are general purpose servo amplifiers with analogue inputs and pulse train interfaces as standard, the range covers 100 W units througt to 7 kW.

The MR-J2S-B servo amplifiers are designed for SSCNET connection in combination with Mitsubishi A series or Q series motion controllers. The motion controllers and servo amlifiers can be linked via the high speed SSCNET network that offer the user: ease of connectivity, due to less wiring, high reliability and since the encoder output terminals are fitted as standard, greater flexibility for system integration. The range also covers 100 W units througt to 7 kW.

The MR-J2S-CL servo amplifiers have built-in positioning functions and incorporates program-driven, single-axis positioning functions, over the features of MR-J2S-A amplifiers. These functions perform positioning operation by creating the position data (target positions), servo motor speeds, acceleration and deceleration time constants, etc. as a program and executing the program. The servo amplifier is the most appropriate to configure a simple positioning system or to simplify a system, for example.

Servo Motors

To address the needs of an unlimited range of applications Mitsubishi has developed a number of brushless servo motors with dynamic characteristics to match the machine performance.

Compact design – all of the motors are extremely compact and have been developed using rare earth magnets (Neodymium Boron Iron) and unique concentrated winding techniques.

Encoder feedback – encoders are fitted to all of the motors and communicate via a high speed serial link with the servo amplifier. This reduces cable size and increases immunity to noise.

Automatic servo motor recognition – as an added benefit of the encoder serial link the servo can also check that the correct motor has been connected. This avoids mismatch and possible damage.

Built-in DC brake – for vertical lifting/lowering applications, motors are available with a built in 24V DC electromechanical brake

Environmental protection – IP65 rating ensures that the motors will withstand tough operating environments.
