4.1How to set parameters
E6581090
Setting monitor mode
The standard default parameters are programmed before the unit is shipped from the factory. Parameters can be divided into three major categories. Select the parameter to be changed or to be searched and retrieved.
Setup parameters | : Parameters necessary for specifying a logic for control input signals |
| and a base frequency for the motor when turning on the inverter for |
| the first time. |

| This parameter setting is needed only for the VFNC1 |
|
| |
| Basic parameters | : Parameters necessary for operating the inverter. |
| ||
| Extended parameters | : Parameters necessary for using various extended functions. |
| Special parameters | : Parameters necessary for using special functions. Three special |
|
| parameters are included in the basic parameters of the |
*1: Three special parameters
CWH : Calls up only functions necessary to meet the user’s needs and, sets up the inverter.
CWJ : Displays the five parameters changed last in reverse order of change. This parameter comes in very handy when readjusting inverter, using the same parameters.
ITW : Displays parameters whose settings are different from the factory default settings. Use this parameter to check settings you made or you want to change.
★Adjustment range of parameters
JK: An attempt has been made to assign a value that is higher than the programmable range. Or, as a result of changing other parameters, the programmed value of the parameter that is now selected exceeds the upper limit.
NQ: An attempt has been made to assign a value that is lower than the programmable range. Or, as a result of changing other parameters, the programmed value of the parameter that is now selected exceeds the lower limit.
If the above alarm is flashing on and off, no setting can be done of values that are equal to or greater than JK or equal to or lower than NQ.
While these codes are flashing on and off, no change can be made to any parameter.
