Initial Settings Chapter 5-1
This section explains the basic settings required to operate and stop the
Inverter. The settings of parameters described here will be sufficient for
simple Inverter operations. First, make these basic settings, then skip to the
explanations of those special functions, even when your application requires
special functions, such as stall prevention, carrier frequency setting,
overtorque detection, torque compensation, slip compensation. Refer to
Chapter 6 Advanced Operation.
5-1 Initial Settings
• The following initial settings are required.
Parameter Write-prohibit Selection/Parameter Initialization (n01): Set n01
to 1 so that n01 through n79 can be set or displayed.
Rated Motor Current (n32): Check the rated current on the motor
nameplate and set the parameter.
Setting the Parameter Write-prohibit Selection/Parameter Initialization (n01)
• Set n01 to 1 so that n01 through n79 can be set or displayed.
Note This parameter makes it possible to write-prohibit parameters, change the
parameter set or displayed range, or initialize all parameters to default values.
Set Value
Setting the Rated Motor Current (n32)
Set the rated motor current (n32) in order to prevent the motor from burning
due to overloading.
Check the rated current on the motor nameplate and set the 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.
