MR-C40A - Servo Amplifier - MITSUBISHI

The MR-C servo amplifier and associated motors HC-PQ and HC-KQ were introduced to serve as a high performance servo solution for customers using stepper motors up to 400 W. The MR-C amplifier was available for 13 years before discontinuation.

Small, Easy-to-Use, HighPerformance. An Extraordinarily Compact, Intelligent Servo.

The MELSERVO-C brushless servo, in a handy super-compact size, is the culmination of Mitsubishi servo technology.

The servo amplifier achieves high performance in an unprecedented compact body, only 40 millimeters wide and 130 millimeters tall. Small but powerful, it comes equipped with a serial encoder, and is packed with high-level features, including real-time auto-tuning and model adaptive control. This servo can substitute for microstep and five-phase stepping motors, and it can be easily used even by first-time users. A “new age” servo for use in a broad range of fresh applications, including semiconductor manufacturing devices, printing machines and electronic component assembly. 

Handy Super-Compact Size

■ Servo Amplifier

• For up to 400 watts, a super-compact size of only 40 millimeters by 130 millimeters was achieved through the incorporation of a newly developed power module and an optimal thermal design made possible with computer-aided engineering techniques.

• Mitsubishi servo control technology including model adaptive control and real-time auto-tuning is achieved with a micro-controller, resulting in the maximum performance with the fewest number of parts. • Select either a single-phase 100 V or 200 V amplifier.

■ Servomotor

• Improved heat dissipation of the motor and a super-compact design were achieved with a molding process that uses newly developed high-thermal conductivity resin. (Frame diameter on 100-watt and below units is 40 millimeters square.)

• This compact design offers maximum torque of 400% (100-watt and below units) through enhanced coil density made possible through original Mitsubishi technology.

• Motors with failsafe electro-magnetic brakes are available.

Easy Operation

■ Real-Time Auto-Tuning

Merely selecting the response setting that fits the machine being used eliminates the need for servo gain adjustments. This is because the real-time auto-tuning function automatically adjusts the gain to fit the machine. And Mitsubishi’s unique control technology model adaptive control makes possible a highly responsive and stable system.

■ Automatic Recognition of Motor Model

The servo amplifier automatically recognizes the drive motor with the motor ID information (motor model name, etc.) built into the encoder. This eliminates the need to set parameters, thereby removing setting errors as well.

■ Easy Operation

• Test operation, monitoring, and parameter setting can all be performed easily using just four buttons.

• The monitoring function allows you to display the status of nine parameters, including motor rotation speed, feedback pulse, command pulse, effective load factor, and peak load factor.

• The servo can remember the conditions that existed during the last four alarms

• Either a 24 V or 5 V power supply can be selected for the I/O that can be user assignable.

• The MR-C can handle three command pulse formats: encoder signals, pulse and direction and CW / CCW pulses.

Migration information:

customers using MR-C amplifiers and motors should migrate to MR-JN, HF-KN and HF-KP products
