Operation
• Parameter initialization is executed using P20 (parameter initialization) in the initial settings mode.
■ Setting the Rated Motor Current (P01)
• Set the motor current parameter in P01 before the trial run to prevent the motor from burning due to
overloading.
• Set the rated current indicated on the specifications nameplate of the motor that is to be used.
• This parameter is used for the electronic thermal function for detecting motor overload (E03). Set-
ting it correctly protects the motor by preventing it from burning even if an overload occurs.
• Motor overload (E03) detection is disabled by setting the parameter to 0.0
• Refer to 3-6-1 Setting the Rated Motor Current for details on the rated motor current (P01).
Note The default setting for the rated motor current is the standard rated current of the maximum
applicable motor.
