Online (EEPROM)
NOTE: Recommended Method of Operation
Online operation with the drive is possible if communications have been established
between the computer and drive. In online (EEPROM) mode, changes to parameter
values are immediately and directly effective in the drive’s EEPROM. In addition, you
can monitor actual values and command setpoints. Online (EEPROM) parameter
values are saved, even if the drive power cycles off and then on.
In online (EEPROM) mode, the device status field indicates an “ok” on a green
background (ok) and the adjacent text message displays Connection with
device ok.
In online (EEPROM) mode:
• All parameter values are read from the drive.
• Parameter changes are written into the drive’s EEPROM.
• You can upload a parameter set file from the drive.
• You can download a parameter set file to the drive.
• You can generate a new parameter set by uploading the parameter set from the drive.
• You can edit process data (for example, entering setpoints, controlling commands, and
sensing actual values).
NOTE: When setting parameters in online (EEPROM) mode, EasyComm monitors
the allowable limit values (minimum and maximum values) for the drive,
including those parameters that depend on the rated drive output.
