Fault during parameter initialisation

¿Qué significa PI ?

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.

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.
