The MELSERVO MR-J4 series of servo amplifiers and the associated positioning units, simple motion modules and high-end motion control systems from Mitsubishi Electric enable machine builders and end customers to increase production safety and improve productivity.
The MR-J4 amplifier series has been developed for the automation requirements of tomorrow. Mitsubishi Electric has incorporated numerous innovative and user-friendly functions to minimise the time-consuming and elaborate matching of mechanical and electronic systems.
The absolute encoder which is fitted as standard has a resolution of 22 bits. This corresponds to more than 4 million pulses/revolution. The result is excellent true-running characteristics and a maximum positioning accuracy and processing speed which more than satisfy the performance requirements of modern high-end machines.
Highlights
- Single, dual and triple-axis amplifiers for improved economy, energy efficiency and cabinet space
- Operation of rotary motors, linear motors and direct drive motors with a single unit
- Safety at all times – STO (Safe Torque Off) and SS1 (Safe Stop 1) in accordance with EN 61800-5-2. SS2/SOS/SLS/SBC and SSM options available
Flexible motor selection
Another highlight of functionality and flexibility is the possibility of connecting different motors to the MR-J4 amplifier. The servo amplifier can be conveniently and easily used with rotary motors, linear motors and also direct drive motors.
User-friendly software
The MR Configurator2 programming tool allows convenient commissioning and diagnostics. Calibration, monitoring, diagnostics, reading and writing of parameters and test operation can be carried out easily on a standard PC. MR Configurator2 ensures a stable machine system, optimum control and short set-up times.
