Panel port communication

What does 7081 mean?

The control panel or PC tool, which is configured as the active control location for the drive, has ceased communicating. This is a programmable fault, influenced by parameter 49.05 (Communication loss action). The auxiliary code specifies the I/O port used for communication (0: Panel, 1: Fieldbus interface A, 2: Fieldbus interface B, 3: Ethernet, 4: D2D/EFB port).

• Loose, disconnected, or damaged physical connection of the control panel or PC tool cable to the drive's port.
• Damaged control panel cable, connector, or the control panel/PC tool itself is malfunctioning.
• Incorrect communication parameters (e.g., baud rate, parity, address) configured between the drive and the control device.
• A fault or malfunction specific to the I/O port identified by the auxiliary code (e.g., Panel port, Fieldbus interface A).

Click steps to track your progress.

1. 1

   Check the physical connection of the control panel or PC tool cable to the drive's port. Disconnect and firmly reconnect it.

2. 2

   Inspect the control panel cable and its connectors for any signs of damage, wear, or bent pins. Replace if necessary.

3. 3

   Verify that the control panel or PC tool itself is powered on and functioning correctly independently of the drive.

4. 4

   Check the auxiliary code to identify which specific I/O port (Panel, Fieldbus A, etc.) has experienced communication loss and focus troubleshooting on that interface.

5. 5

   Review relevant communication parameters (e.g., in parameter groups 50 for panel, 58 for embedded fieldbus) to ensure they are correctly configured for the active control location and communication method.
