Outline Drawing
4th axis spec (Fanuc spec.)
  • The maximum instantaneous holding torque and maximum continuous holding torque are the values used by Kitagawa QUINTE controller, and the those values differ when using for the 4th axis.
  • When wishing to shorten the tact time, it is effective to hold only by the motor torque without using the mechanical brake. At that time, the clamp torques shall be the maximum continuous holding torque.
  • When not using the mechanical brake, hold it with the motor torque while it is stopped.
  • When the mechanical brake is not used, the stop position is not held when the power is turned off or when the servo alarm occurs. The table may rotate at startup and restart.
  • When RK201 is installed on the FANUC RoboDrill, the motor will be αiF8/3000-B, and the specifications will change.
