1.2.12 Inverter-driven 400V class motor

In the PWM type inverter, a surge voltage attributable to wiring constants is generated
at the motor terminals. Especially for a 400V class motor, the surge voltage may
deteriorate the insulation. When the 400V class motor is driven by the inverter,
consider the following measures:

•

Measures

It is recommended to take either of the following measures:

(1) Rectifying the motor insulation

For the 400V class motor, use an insulation-enhanced motor. Specifically
1) Specify the "400V class inverter-driven, insulation-enhanced motor".
2) For the dedicated motor such as the constant-torque motor and low-vibration

motor, use the "inverter-driven, dedicated motor".

(2) Suppressing the surge voltage on the inverter side

On the secondary side of the inverter, connect the optional surge voltage
suppression filter (FR-ASF-H).

CAUTION

When the wiring length between the motor and inverter is 40m or more, take

the above countermeasure and also set the long wiring mode in Pr. 70 "Soft-

PWM setting". (Refer to page 113 for Pr. 70.)
