• Initialize the parameters using the following procedure.
• To initialize the parameters, set n01 to 8.
4-2-4 Setting the Rated Motor Current
• Set the motor current parameter in n32 in order to prevent the motor from
burning due to overloading.
Setting the Rated Motor Current
• Check the rated current on the motor nameplate and set the motor current
parameter.
• This parameter is used for the electronic thermal function for motor
overload detection (OL1). By setting the correct parameter, the
overloaded motor will be protected from burning.
Note 1. The standard rated current of the maximum applicable motor is the default
rated motor current.
2. Motor overload detection (OL1) is disabled by setting the parameter to 0.0.
