Fault during parameter initialisation

What does PI mean?

An error was detected during the parameter set transfer between two devices, or the parameter set does not match the controller (e.g., if data was transferred from a higher-power controller to a lower-power controller). This can lead to incorrect drive configuration.

• Attempting to transfer a parameter set from a different hardware variant or power rating (e.g., from a 22kW drive to an 11kW drive).
• Mismatched firmware versions between the source and target devices during parameter transfer, causing structural incompatibilities.
• Data corruption during serial communication (e.g., RS485, Ethernet) between devices due to noise or incorrect cabling.
• Insufficient memory space on the target device to accommodate the transferred parameter set (less common).
• Device power interruption during the critical parameter initialization phase after a transfer or boot-up.

Click steps to track your progress.

1. 1

   Verify the hardware type and firmware version of both the source and target devices are identical or fully compatible before transferring.

2. 2

   Use the manufacturer's official software tool to create a compatible parameter file for the specific target device model and firmware.

3. 3

   Inspect the communication cable (e.g., USB, Ethernet, RS485) between devices for damage or loose connections, replacing if necessary.

4. 4

   Try to load a factory default parameter set (e.g., using P0-01 = 0) on the target device before attempting a transfer again.

5. 5

   Ensure a stable power supply to both devices throughout the parameter transfer and initialization process.

6. 6

   Manually review critical parameters (e.g., motor nominal current P3-00, motor power P3-01) for consistency with the target drive's ratings.
