Example
In the above example, the value of AC120 (1st Acceleration Time 1) is incremented by 1 every second.
ChgParam
Command Description Argument
Changes the data of the inverter parameter
specified in <parameter> to <value>.
You can change any inverter parameter.
Parameter: parameter code
(Fxxx, Axxx, bXXX, Cxxx, Hxxx, or Pxxx)
Value: any variable or constant

<parameter> : = <value>
Note 1. Similar to the settings with the inverter's LCD Operator, each parameter has the following restrictions.
If any of the event listed in the restrictions occurs, the inverter detects Command Error (E045) and the
DriveProgramming program is stopped. For details on restrictions for each parameter, refer to the
High-function General-purpose Inverter 3G3RX2 Series User's Manual (I620).
• Data that exceeds the setting range was set to the parameter.
• A matching error occurred between the parameter to set and relevant parameters.
• A function which is not available with the selected mode was set.
• The parameter that cannot be changed during operation was changed during operation.
• A parameter was set while parameter data change is prohibited with the Soft Lock Selection (UA-16).
2. Even if you change the set parameter data by using the “ChgParam” command, the data of the corre-
sponding parameter is not changed in the EEPROM.
