A171
Magnetizing

A172

*The values shown for parameter A001 (Rated Voltage) is for 60 Hz. For 50 Hz., the rated voltage for the
(200V Class) is 220V and for the (400V Class) is 440V.
1.) Initially the drive HP code, parameter A175, sets the factory default motor internal parameters (A168 – A172)
as shown in the above table. These parameters are used for Vector Control Mode only (A000 = 0000 or 0001)
and are not used in V/F Control Mode (A000 = 0002).
2.) When an auto-tune is performed (A006 = 0001), the motor internal parameters (A168 - 172) will be automatically
updated to the values measured during the auto tune process. These values are maintained when a factory
reset is performed.
3.) If the motor is replaced, the auto-tune procedure must once again be carried out. If the parameters (A168 – 172)
are known, they may be entered directly without auto-tuning.
4.) The motor parameters (A168 to A172) will be modified to the factory setting under any operation mode, when
changing the Drive Horsepower code (A175).
