Parameter Control Commands

ChgParam
Command
Changes the data of the inverter parameter
specified in <parameter> to <value>.
You can change any inverter parameter.
Note 1. Similar to the settings with the inverter's Digital Operator, each parameter has the following restrictions. If any of the
event listed in the restrictions occurs, the inverter detects the command error 1 (E45) and the Drive Programming
program is stopped. For details on restrictions for each parameter, refer to Section 7 Precautions for Use of Param-
eters for Drive Programming and the MX2 User's Manual (I570-E2) or the RX User's Manual (I560-E2).
• 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 (b031).
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. To change the data both in the program and in
the EEPROM, execute the "ChgParam" command immediately after the "eepwrt" command.
 Example
In the above example, the value of F002 (1st Acceleration Time 1) is incremented by 1 every second.
Block number
1 Adds 1 to U(02).
2 Assigns U(02) to the parameter F002.
3 Waits for 1.00 second with the "wait" command.
4 Jumps to the block 1: loop_ unconditionally.
