Initial Settings - Omron SYSDRIVE 3G3JV User Manual

Basic Operation
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 opera-
tions.
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. Re-
fer to Chapter 6 Advanced Operation.

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.
H Setting the Parameter Write-prohibit Selection/Parameter Initialization
(n01)
• Set n01 to 1 so that n01 through n79 can be set or displayed.
n01
Parameter Write-prohibit Selection/Parameter
Initialization
Setting 0, 1, 5, 6, 8, 9
range
Note This parameter makes it possible to write-prohibit parameters, change the parameter set or dis-
played range, or initialize all parameters to default values.
Set Values
Value
0 Only n01 can be displayed and set. The n02 through n79 parameters can be displayed only.
1 The n01 through n79 parameters can be displayed and set.
5 Enables continuous operation. (Parameters n01 to n79 can be set or monitored.)
6 Only the error log memory is cleared.
8 Enables the initialization of all parameters in 2-wire sequence so that the parameters will
return to default values.
9 Enables the initialization of all parameters in 3-wire sequence.
Note With settings 0 or 1, operation commands are ignored in Program Mode. (Refer to 3-1-2 Drive
Mode and Program Mode.) Normally, use a setting of 0 or 1.
H 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.
