Inovance drive error code 14 relates to communication issues between the drive and another device on the Modbus network. Modbus is a common industrial communication protocol used to exchange data between devices like drives, PLCs (Programmable Logic Controllers), and HMIs (Human-Machine Interfaces).

Here's a breakdown of the error and potential solutions:

Error Description:

• Code: 14
• Meaning: Modbus communication error

Possible Causes:

• Incorrect Communication Settings: There could be a mismatch between the communication settings configured on the Inovance drive and the other device on the Modbus network. Settings like baud rate, parity, and slave address need to be identical for proper communication.
• Connection Issues: Faulty or loose cables connecting the drive to the network can disrupt communication.
• Device Malfunction: In rare cases, a malfunctioning device on the Modbus network could be causing the communication error.

Troubleshooting Steps:

1. Verify Communication Settings: Consult the user manuals for both the Inovance drive and the other device on the network. Ensure all communication settings (baud rate, parity, slave address) are configured identically on all devices.
2. Inspect Cables: Visually inspect the Modbus network cables for any signs of damage or loose connections. Ensure all connectors are securely fastened.
3. Test Network Communication: If possible, try isolating the Inovance drive and the other device on a temporary network to test communication. This can help identify if the issue is with the overall network or specific device configuration.
