I. Introduction to Operation Panel Functions and Password & Parameter Settings

The operation panel of the Ribbo Inverter RB5000 series is designed to be intuitive and user-friendly, facilitating various operations and settings. The panel mainly includes keys such as PRG/DRIVE, ▲▼, SET, RUN, STOP, JOG, MENU, and multiple indicator display windows.

Password Setting and Cancellation: The RB5000 series inverter does not directly mention a password setting function, but certain parameters in the High-level Parameter Group (HP) may involve access restrictions. To set similar password-like access restrictions, the HP-03 parameter can be modified to set the parameter group modification permissions. For example, setting HP-03 to a non-zero value will restrict access and modification to the AP, LP, HP, and PP parameter groups.

Parameter Access Restriction: By setting the HP-03 parameter, users can restrict access and modification permissions to the inverter parameters. For instance, when HP-03=0, all parameter groups can be viewed and modified; when HP-03=1, only the AP parameter group can be viewed and modified, while the other parameter groups can only be viewed.

Restoring Factory Default Settings: To restore the inverter parameters to their factory settings, the HP-03 parameter can be set to 07 or 08, which will not only restore all parameters to their factory defaults but also set the inverter to two-wire or three-wire start/stop control mode.

II. Terminal Forward/Reverse Control and External Potentiometer Speed Regulation

Terminal Forward/Reverse Control: The RB5000 series inverter supports motor forward/reverse control through external terminals. First, the control mode needs to be set to terminal control by setting the HP-04 parameter to 1. Then, depending on the requirements, the HP-03 parameter can be set to select two-wire or three-wire control mode. In two-wire control mode, terminal X1 is the forward start/stop command, and terminal X2 is the reverse start/stop command. In three-wire control mode, terminal X1 is the forward start command, terminal X2 is the reverse start command, and terminal X5 is the stop command.

External Potentiometer Speed Regulation: To regulate speed using an external potentiometer, the frequency command source needs to be set to external analog input by setting the HP-05 parameter to 1. Then, connect the external potentiometer to the VS terminal (voltage input, 0-10V) and GND terminal (common ground). Depending on the output characteristics of the potentiometer, the LP-05 (analog voltage frequency command gain) and LP-06 (analog voltage frequency command offset) parameters may also need to be adjusted to ensure that the speed regulation range matches the potentiometer output range.

III. Fault Codes and Troubleshooting
