Cause : Incorrect motor data identification comes when an attempt to perform motor data identification (also known as motor parameter identification or commissioning) but there is an issue with motor data or motor connection.

f7990 siemens indicates Incorrect motor data identification. This means fault occurs during or after an attempt to perform motor data identification (also known as motor parameter identification or commissioning).

Troubleshooting Steps:

Follow these steps to correct f7990 siemens:

• Check and ensure that all motor parameters (p0300 series) in the drive exactly match the motor's nameplate.
• Confirm that the motor is correctly wired to the drive's output terminals (U, V, W) according to the motor's connection diagram.
• Make sure the motor is physically connected to the drive before attempting motor data identification.
• Verify that the drive's current and power rating are reasonably matched to the motor's requirements. A very large drive controlling a very small motor (or vice versa) might lead to identification issues.
