  • Page 369: Installation

    Installation Observe the following precautions when installing an MxC. Using Enclosures Either install the MxC in a clean location free of oil mist, air-bourne matter, dust, and other contaminants, or install the MxC in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the MxC does not rise above allowable limits.
  • Page 370 MxC Application Precautions Magnetic Contactor Installation Do not start and stop the motor frequently when using a magnetic contactor installed on the power supply line. Doing so can cause the MxC to malfunction. The MxC should not be switched on and off more than once every 30 minutes when using a magnetic contactor.

  • Page 371: Motor Application Precautions

    Cooling effects diminish in the low-speed range, resulting in higher motor temperatures. The motor torque should be reduced in the low-speed range whenever using a non-Yaskawa motor. If 100% torque is required continuously at low speeds, consider using a special inverter or vector motor.

  • Page 372: Using The Mxc For Motors Other Than Standard Yaskawa Motors

    The MxC can drive three-phase induction motors with two, four, or six poles. The MxC cannot run PM motors, motors for machine tools, or multi-pole motors with eight poles or more. If using the MxC with a motor not made by Yaskawa, contact your Yaskawa representative. Power Transmission Mechanism (Speed Reducers, Belts, and Chains) If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will be affected when the motor operates only in the low speed range.
