Study notes

  • The MG400 uses servo motors and a high-precision encoder; its drive and controller are integrated in the all-in-one base.
  • Programming options are drag-to-teach, Lua, and a graphical interface.
  • The ENC interface supports ABZ encoders.
  • Communication interface includes TCP/IP and Modbus TCP; port 502 is used for Modbus by default and should not be occupied.
  • Base size is 190 mm × 190 mm.
  • Rated voltage is 48 V.
  • Maximum payload is 750 g; the specification table lists payload as 500 g (max. 750 g).
  • The base includes a built-in cooling fan.
  • Installation is desktop.
  • Vibration suppression algorithm is stated to increase multi-joint motion stability time by 60% and reduce residual vibration by 70%.

Safety

  • Collision detection is included for human collaboration.
  • J2 and J3 motors have brakes.
  • Operating environment limit is 0 to 40 °C.
