Installation
While power is ON or for some time after power-OFF, do not touch
the motor since the motor will be extremely hot. Touching these
devices may cause a burn.
The outline dimensions of MM-EF motors and standard motors are
different. (It is the same for MM-EFS and the standard motors.)

Standard models can be installed as they
are.
Dedicated models are required.
Not available as installation strength is
insufficient.
The floor installation condition is applicable to a slope of up to 30. If
the slope is steeper, apply the wall installation condition.
To install a horizontal motor to a wall, first attach a shelf that supports
the motor legs.

Wiring
Applying the commercial power supply to input terminals (U, V, W) of
an IPM motor will burn the IPM motor. The IPM motor must be
connected with the output terminals (U, V, W) of the inverter.
An IPM motor is a motor with interior permanent magnets. High
voltage is generated at motor terminals while the motor is running.
Before wiring or inspection, the motor must be confirmed to be
stopped. In an application, such as fan and blower, where the motor
is driven by the load, a low-voltage manual contactor must be
connected at the inverter's output side, and wiring and inspection
must be performed while the contactor is open. Otherwise you may
get an electric shock. The inverter power must be turned ON before
closing the contacts of the contactor at the output side.
Match the input terminals (U, V, W) of the motor and the output
terminals (U, V, W) of the inverter when connecting.
Use the following length of wiring or shorter when connecting an
IPM motor.
Pr.72 PWM frequency selection
400V class 0.4K
Setting (carrier frequency)
4 (2.5kHz) or less
5 (5kHz) or higher
Use one dedicated IPM motor for one inverter.
Multiple IPM motors cannot be connected to an inverter.
Operation
It takes approx. 0.1s (magnetic pole detection time) to start a motor
after a start signal is input.
An IPM motor is a motor with interior permanent magnets.
Regression voltage is generated when the motor coasts at an
instantaneous power failure or at a flying start. The inverter's DC bus
voltage rises if the motor coasts fast or make a flying start in this
condition. When using the automatic restart after instantaneous
power failure function, it is recommended to also use the
regenerative avoidance operation to start up smoothly.
The number of poles of the dedicated IPM motor is six.
The relationship between the speed and frequency setting is
calculated as:
