CAUTION
• Be sure that the ground terminal is properly grounded using a wire of the recommended size.
CAUTION
WARNING
200 V class: Ground to 100 Ω or less 400 V class: Ground to 10 Ω or less
If a wire smaller than the recommended size is used, the MxC may not operate properly.
• Check to be sure that the voltage of the main AC power supply satisfies the rated voltage of the
MxC.
Injury or fire may occur if the voltage is not correct.
• Do not perform voltage tolerance tests on the MxC.
Such tests may damage semiconductor components and other devices.
• Tighten all terminal screws to the specified tightening torque.
Failure to do so may result in fire.
• Do not connect AC power to output terminals U, V, and W.
Circuitry in the MxC will be damaged if voltage is applied to the output terminals.
• Do not wire AC power lines to terminals p1, n1, r2, s2, or t2. These terminals are used for connecting peripheral devices only.
Applying voltage to these terminals will damage the MxC.
• Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.
The MxC may be damaged and circuitry may overheat if these devices are connected.
• Do not connect electromagnetic switches or magnetic contactors to the output circuits.
If a load is connected while the MxC is operating, a power surge will trigger the overcurrent protection circuit in the MxC.
Setting Parameters
• Disconnect the load (machine, device) from the motor before performing Rotational Auto-Tuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor constants cannot be correctly set
with the motor attached to a load.
• Stay clear of the motor during Rotational Auto-Tuning.
The motor may start operating suddenly when stopped, possibly resulting in injury.
Te s t R u n
• Make sure that the front cover is properly attached before turning on the power supply.
Failure to do so may result in electric shock.
• Leave a reasonable amount of space between yourself and the application when using the fault
reset function. The machine may start moving suddenly once the alarm is cleared.
The application should be designed to ensure safety when the MxC is restarted.
Failure to do so may result in injury.
• Provide a separate emergency stop switch (the STOP key on the digital operator works only when
it has been enabled).
Failure to do so may result in injury.
• Reset alarms only after confirming that the RUN signal has been switched off.
Failure to do so may result in injury.
iv
CAUTION
• Do not touch the cooling fins (heatsink), braking resistor, or Braking Resistor Unit. These compo-

nents can become extremely hot.
These components become hot enough to cause serious burns.
• Be sure that the motor and machine is within the applicable ranges before starting operation.
Failure to do so may result in injury.
• Provide a separate holding brake if necessary.
The external sequence should be designed to ensure that the holding brake is activated in the
event of an emergency, power failure, or fault in the MxC.
Failure to do so may result in injury.
• If using an MxC with an elevator, take proper steps to ensure safety and to prevent the elevator
from falling suddenly.
Failure to observe to do so may result in injury.
• Refrain from checking relay signals while the MxC is running.
Failure to do so may result in damage to the application.
• Be careful when changing any settings in the MxC. The default settings when the MxC is first
shipped are generally set to optimal values.
Failure to do so may result in damage to the application.
Maintenance and Inspection
• Do not touch the MxC terminals. Some of the terminals carry high voltages and are extremely dangerous.
Failure to do so may result in electric shock.
• Always have the protective cover in place when power is being supplied to the MxC. When attaching the cover, always turn off power to the MxC through the MCCB.
Failure to do so may result in electric shock.
• After turning the main circuit power supply off, wait until the CHARGE display light goes out before
performing maintenance or inspections.
The capacitor will remain charged and is dangerous.
• Maintenance, inspection, and replacement of parts must be performed authorized personnel only.
Remove all metal objects, such as watches and rings, before starting work. Always use grounded tools.
Failure to heed these warning may result in electric shock.
• Customers must provide the holding brakes.
Before making any adjustments other than those done in actual operations, be sure to tighten the holding brakes by using
an external sequence.
Failure to do so may result in electric shock.
• If the MxC is used with an elevator, be sure to take safety measures to prevent the car from falling.
Failure to do so may result in electric shock.
• A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully.
The CMOS IC may be destroyed by static electricity if touched directly.

WARNING
CAUTION
• Do not attempt to modify or alter the MxC.
Failure to do so may result in injury or electric shock.
• Contact your Yaskawa representative if you intend to use the MxC with a non-Yaskawa motor or
any other motor not listed in Yaskawa product literature.
The MxC can be used with three-phase induction motors with 2, 4, or 6 poles. A multi-pole motor with 8 poles or more, a
PM motor, or a motor designed for use with machine tools cannot be used with the MxC.
• Install adequate branch circuit short circuit protection per applicable codes.
Failure to comply may result in damage to the MxC.
The MxC is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes, 220 Vac maximum (200 V Class) and 480 Vac maximum (400 V Class).
• If disinfectants or insecticides must be used to treat packing materials such as wooden frames, pallets, or plywood, the packing materials must be treated before the product is packaged, and methods other than fumigation must be used.
Example: Heat treatment, where materials are kiln-dried to a core temperature of 56
minutes or more.
If the electronic products, which include stand-alone products and products installed in machines, are packed with fumigated wooden materials, the electrical components may be greatly damaged by the gases or fumes resulting from the fumigation process. In particular, disinfectants containing halogen, which includes chlorine, fluorine, bromine, or iodine can
contribute to the erosion of the capacitors.

Introducing the MxC
The design of the MxC is simpler and more efficient than a conventional inverter. The MxC uses a different
mechanism to generate AC voltage, and relies on nine bi-directional switches to adjust AC output power to the
motor directly from an AC line power input.
The MxC has no rectifying diodes and no DC bus capacitors commonly used in inverters.

MxC Model Numbers
The model number of the MxC on the nameplate indicates the specification, voltage class, and maximum
motor capacity of the MxC in alphanumeric code.
Fig 1.2 MxC Model Numbers
MxC Specifications
The MxC specifications (“SPEC”) on the nameplate indicate the voltage class, maximum motor capacity, the
protective structure, and the version of the MxC.
Fig 1.3 MxC Specifications
Open Chassis Type (IEC IP00)
Protected so that no one can come in direct contact with electrically charged parts from the front when the
MxC is mounted in a control panel.
Enclosed Wall-Mounted Type [IEC IP20, NEMA 1 (Type 1)]
The MxC is structured so that the MxC is shielded from the exterior, and can thus be mounted to the interior
wall of a standard building (not necessarily enclosed in a control panel). The protective structure conforms to
the standards of NEMA 1 (Type 1) in the USA. The protective covers are required for an IEC IP20 or NEMA 1
(Type 1) protective structure.

Checking and Controlling the Installation Site
The MxC must be installed and used in an area that complies with the conditions listed below. Maintain
the conditions of the area for proper performance life.
Installation Site
Install the MxC under the following conditions, making sure that the area complies with Pollution Level 2 or
less (as defined by UL standards).
Table 1.6 Installation Site
Type Ambient Operating Temperature Humidity
Enclosed wall-mounted -10 to + 40 °C 95% RH or less (no condensation)
Open chassis -10 to + 45 °C 95% RH or less (no condensation)
The MxC should be installed:
• in a clean location free from oil mist and dust.
• in an environment where metal shavings, oil, water, or other foreign materials do not get into the MxC.
• in a location free from radioactive materials and combustible materials (e.g. wood).
• in a location free from harmful gases and liquids.
• in a location free from excessive oscillation.
• in a location free from chlorides.
• in a location away from direct sunlight.
Controlling the Ambient Temperature
To get optimum performance and full product life, the MxC should be installed in an environment free of
extreme temperature changes. If the MxC is installed in an enclosed environment such as a box or enclosure
panel, use a cooling fan or air conditioner to keep the internal air temperature below 45°C.
Protecting the MxC from Foreign Matter
Place a cover over the MxC during installation to shield it from exposure to metal particles when drilling.
Always remove the cover from the MxC after completing installation. Failing to do so will reduce ventilation
and possibly cause the MxC to overheat.
