‹ 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. The power transmission mechanism will
make noise and experience problems with service life and durability if the motor is operated at a speed higher
than 60 Hz.
