I. Introduction to the Operation Panel Functions and Parameter Management

1.1 Introduction to the Operation Panel Functions

The operation panel of the EACON Inverter EC590 consists of LED digital displays, LEDs, and function buttons, capable of displaying the inverter’s operating status, frequency, current, voltage, and other parameters. The main buttons on the panel include RUN, STOP/RESET, PRG/SET, and MF.K (multi-function key). Through the operation panel, users can conveniently perform parameter settings, monitor operating status, reset faults, and other operations.

1.2 Copying Parameters to Another Inverter

To copy the parameters from one EACON Inverter EC590 to another, follow these steps:

1. Ensure Identical Model Numbers: The premise for copying parameters is that both inverters must be of the same model to ensure parameter compatibility.
2. Enter Parameter Copy Mode: On one inverter, press the PRG/SET button to enter the parameter setting mode, locate and set parameter FP-00 to a non-zero value (e.g., 1234) to enable the parameter copy function.
3. Connect the Communication Cable: Use a dedicated communication cable to connect the communication interfaces of both inverters.
4. Initiate the Copy Process: On the source inverter, press and hold the MF.K button for several seconds until the panel displays “COPY,” indicating that the copy process has started. At this time, the target inverter should be in standby mode.
5. Complete the Copy: Once the copy process is complete, the source inverter’s panel will display “END,” indicating that the parameters have been successfully copied to the target inverter. At this point, the communication cable can be disconnected, and the FP-00 parameters of both inverters set to 0 to disable the parameter copy function.

1.3 Initializing Parameters

To initialize the parameters of the EACON Inverter EC590, follow these steps:

1. Enter Parameter Setting Mode: Press the PRG/SET button to enter the parameter setting mode.
