The MR-J2S-20A1 model by Mitsubishi offers versatile and efficient performance for any job. This reliable servo amplifier was made to tackle a variety of tasks with its three distinct control modes: position, speed, or torque - allowing the flexibility needed in a demanding production environment.

This MR-J2S-20A1 model has a bevy of protective features for maximum user safety, including overcurrent cutoff, regenerative overvoltage cutoff to prevent electrical surge risks, encoder error protections, and shutdown safeguards. It also comes with adjustable speed limiters acting as an extra layer of caution when operating the device.

Technical Specifications of MR-J2S-20A1:

The model MR-J2S-20A1 utilizes natural convection to maintain the optimal temperature within its housing. It is equipped with a dynamic brake and an inrush current of 30 Amps (which quickly attenuates to 5 Ams after 10 ms). This model MR-J2S-20A1 also has a reliable voltage supply between 100 and 120 VAC, capable of accommodating up to 5% frequency variations for more precise position control through motor rotational speed and directional pulse train technology.

The MR-J2S-20A1 boasts a high-performance sine wave PWM and an efficient current control system. Its speed command inputs accept 0 to +/- 10 VDC, while its torque commands use between 0 and +/- 8 VDC. In addition, the model offers an adjustable torque range from 0 up to - or +10 VDC when installed in either parameter setting or external analog input mode.

Position and speed control are easy with this unit, capable of processing up to 200 kbps when in position mode or 500 kbps for differential receivers. For enhanced performance, while controlling speeds between 1:2000 - 1:5000, the analog or internal command may be suitable depending on application requirements.

Operating and Installation Conditions (MR-J2S-20A1):

The MR-J2S-20A1 servo amplifier guarantees optimal performance even when installed in areas with challenging climates, such as up to 1000 meters above sea level or temperatures of 0 - +55 degrees centigrade (non-freezing). You must consult an expert technician for proper installation to ensure consistent functioning at the highest standards and full safety measures. Moreover, transportation and storage should occur between -20°C/+65 °C (non-freezing) while keeping it upright away from any vibration sources.

Industrial applications such as the MR-J2S-20A1 servo amplifier must be installed within a secure and reliable control cabinet in an indoor environment free from pollutants. Allowing proper clearance between the device and its protective housing is essential for the optimal performance of this machinery.

General Cautionary Information of MR-J2S-20A1

The MR-J2S-20A1 servo amplifier provides flexible power solutions for a wide array of industrial applications. To ensure the utmost safety and protect those interacting with it, its protective earth connections must be firmly connected to any applicable leakage current breakers to prevent electric shock or other hazardous outcomes.

To ensure the successful installation of a servo amplifier MR-J2S-20A1, it's essential that machines meet several conditions encompassing electromagnetic compatibility, in addition to requirements concerning their electrical equipment and operating environment.

With every servo amplifier produced, sustaining exceptional quality is at the forefront of the production process. A complete failsafe system has been incorporated for optimal protection and assurance to enhance product security when potential harm occurs if malfunctions arise.
