Description

Designed for precise positioning and motion control, the MR-J2S-20CL drives AC servo motors in high-performance industrial automation setups. This MELSERVO-J2S series unit integrates a built-in programming function, allowing the execution of simple positioning programs directly within the amplifier. This local intelligence eliminates the need for an external positioning module in many basic applications, reducing system complexity and overall panel space. Using a sine-wave PWM control system, the unit maintains highly accurate current feedback to ensure smooth torque delivery across its full operational range.

The MR-J2S-20CL supports both absolute position detection and incremental value command methods, giving control system designers flexibility in axis homing and feedback tracking. Safety and reliability are managed via integrated diagnostic capabilities, including protection against overcurrent, overvoltage, and thermal overload. The self-cooling IP00 physical design is optimized for cabinet mounting near companion controllers or PLCs.

Features

  • Built-in program positioning capability with a 120-step capacity configured via setup software.
  • Flexible power input support for single-phase or three-phase AC configurations.
  • Integrated dynamic brake system for swift, controlled deceleration.
  • Advanced protective shutdowns covering overcurrent, regenerative overvoltage, and overload.
  • Dual-system compatibility supporting signed absolute value and signed incremental command protocols.
  • Natural self-cooling thermal management within a compact physical footprint.

Applications

  • Packaging, indexing, and labeling machinery
  • Material handling systems and multi-axis conveyors
  • Precision X-Y gantry positioning tables
  • Textile, paper, and printing machine drive units
  • Food processing and assembly automation lines

Installation Guidelines

  • Mount the unit vertically on a rigid, flat surface to optimize vertical heat dissipation via natural convection.
  • Maintain a minimum of 10 mm clearance on either side and 40 mm above/below the drive to ensure proper thermal airflow.
  • Ensure the protective earth (PE) ground terminal is directly connected to the main control panel's ground busbar.
  • Isolate high-power motor and AC input cables from sensitive feedback and control wiring to prevent electromagnetic noise coupling.

FAQ

What is the program capacity of the MR-J2S-20CL servo amplifier?

The MR-J2S-20CL features an integrated programming capacity of up to 120 steps, allowing simple positioning programs to be run directly on the drive.
