MR-J2S-70A

The Mitsubishi servo drive MR-J2S-70A is a highly efficient model with varying practical applications. It features a very generous frequency fluctuation tolerance of 5 percent, and the voltage supply range for its three-phase power input ranges from 170 to 253 volts of alternating current (VAC).

Technical Specifications of MR-J2S-70A:

The model MR-J2S-70A is equipped with a finely tuned current control system and dynamic brake, enabling superior accuracy in the positioning of its motor. This rotational speed and direction are controlled through the technical use of high-speed pulse train signals.

Boasting three distinct control modes, the model MR-J2S-70A can expertly switch between them as needed. From position and speed to torque - each mode has its set parameters or analog inputs, which allow users to adjust their maximum velocity up or down from a range of 0-10 VDC.

This light yet capable 1.7 kg model MR-J2S-70A offers an array of safety features, such as Overcurrent shut-off to avoid too much current flow, Regenerative overvoltage shut-off for security against sudden power changes and voltage spikes, Encoder error prevention to ensure exact commands are being executed correctly every time, Instantaneous Power Failure Protection that safeguards the system from unexpected shutdowns or surges overloads.

The MR-J2S-70A servo amplifier offers three distinct operational modes: position, speed, and torque control. Its robust design has a self-cooling housing connected to blowers for forced air circulation. Furthermore, the manual input commands offer an adjustable voltage range from 0 up to +/- 10 VDC (speed) or even +/- 8 VDC (torque).

The MR-J2S-70A model's differential receiver capacity is an impressive 500 kpps, while the open collector offers a maximum of 200 kpps when in position control mode. Analog and internal speed controls are accessible across a wide range of ratios, 1:2000 to 1:5000, respectively.

Operating and Installation Conditions:

The MR-J2S-70A model boasts a wide operating temperature range from the cool 0°C to warm +55°C, allowing for some flexibility in environmental conditions. Furthermore, it has an extended storage temperature range of -20℃ to +65℃ and withstands humidity levels of up to 90 percent relative humidity.

To achieve optimal results, always position the device vertically – this way can avoid high vibrations and ensure peak performance at all times.

To attain optimum performance, the model MR-J2S-70A must be placed in an upright orientation to counteract excessive vibrations. When installing a single servo amplifier, it's crucial to ensure there is 10 mm of clearance on both sides and 40mm above and below it for optimal results.

The control cabinet should feature built-in protection against temperature fluctuations to ensure optimal operation. It's important to leave enough room within the cabinetry for a servo amplifier - allowing space between it and the top of the enclosure ensures that heat generated by components is not trapped in an enclosed area.

General Information

When working with a servo amplifier MR-J2S-70A, it is important to guarantee that all components are present and in their original condition; tampering should be avoided. To make sure your servo amp runs smoothly for extended periods, always ensure its protection from interferences such as screws, oil spills, or flammable objects nearby.

Servo amplifiers are sensitive devices that, over time, can suffer from electrical system deterioration. As part of its preventative maintenance plan and to safeguard against malfunctioning machinery-related calamity, the electrolytic capacitor contained within must be replaced every decade for optimal performance in any given environment.

To ensure optimal performance, the servo drive MR-J2S-70A must be wired correctly. If not done properly, unexpected results may occur and cause heat generation from loose contact between the cable and terminal block. To avoid this risk, carefully tighten cables to their specified torque setting for a secure connection.
