Mitsubishi MR-J2S-70CP

The MR-J2S-70CP model weighs 1.7 kilograms and incorporates a built-in dynamic brake. The dynamic brake has a load-inertia moment ratio of 30 times. The integrated dynamic brake might overheat if the inertia moment exceeds this value. The voltage ranges from 200 to 230 VAC for the three-phase supply and 230 VAC for the single-phase supply. The input voltage frequency should be between 50 and 60 hertz. Some of the protection functions included in the model are an overcurrent cutoff, servo motor overheats protection, regenerative fault prevention, Undervoltage protection, Overspeed protection, and excessive error protection.

The servo amplifier MR-J2S-70CP is fitted with three distinct modes of operation: an automated operation mode, a manual operation mode, and a manual home position return mode. The MR-J2S-70CP model's high-end features include absolute position sensing, a backlash function, a software stroke limit, and an override by an external analog signal.

The servo amplifier MR-J2S-70CP sustains the same level of performance at elevations of up to 1,000 meters above sea level. Due to its low protection category, the device requires vertical mounting in an IP54-rated control cabinet. This model's optimal operating temperature range is between 0 and +55 degrees Celsius with a maximum relative humidity of 90 %. Dust, oil mist, and other reactive substances should not be present during installation and operation. The model can bear vibrations of 5.9 m/s2 or less without degrading the performance.

The module MR-J2S-70CP has a recommended storage temperature range of -20 to +65 degrees Celsius, with a maximum relative humidity of 90%. To prevent the internal temperature of the box from rising over the ambient temperature, it is advised that, when installing several servo amplifiers, at least 100 mm of space be provided between the top of each servo amplifier and the interior of the control cabinet. The servo amplifier's air inlet and outlet must not be covered. And if it doesn't happen, a malfunction is possible.

The MR-J2S-70CP servo amplifier's built-in communication feature is leveraged by the MR Configurator software (MR2JW3-SETUP151E version or more) to allow various tasks on a computer, including the modification of settings, the display of graphs, the execution of tests, etc. This software is capable of various diagnostic and testing procedures and file-processing tasks. The software contains extensive capabilities such as machine simulation, machine analyzer, and gain search.

The software supports Windows XP and needs a free 60 MB or more hard drive space. In the motorless feature of the software, the servo amplifier delivers output signals and displays the status as though the servo motor is operating in response to the external input signal, even when no servo motor is connected. The MR-J2S-70CP servo amplifier has a 5-digit, 7-segment LED display on the front panel that may show status, changing settings, etc. Adjust the settings in advance, determine the cause of an alert, verify the correct order of external events, and check the state of the current operation.
