Motor parameter incorrect

What does F07950 mean?

The motor parameters were incorrectly entered during commissioning, such as setting p0300 (Motor type) to 0, indicating no motor. The fault value (r0949) specifies the particular parameter number involved. Incorrect motor parameters can lead to inefficient operation, instability, motor damage, or the drive failing to start.

• Basic motor identification parameter P0300 (Motor type) set to 0, indicating no motor selected or specified.
• Essential motor nameplate data (P0304 (Motor rated current), P0305 (Motor rated voltage), P0307 (Motor rated power), P0310 (Motor rated frequency), P0311 (Motor rated speed)) entered incorrectly.
• Encoder parameters (e.g., P0408 (Encoder pulses), P0410 (Encoder direction)) misconfigured for the specific motor or application.
• Motor temperature sensor type (P0601) or motor cooling type (P0600) set incorrectly, leading to internal calculation errors.
• Motor identification run (P0340) attempted with incorrect or incomplete motor data, leading to a failed identification.

Click steps to track your progress.

1. 1

   1. Read parameter r0949 to identify the specific motor parameter causing the fault.

2. 2

   2. Verify all motor nameplate data (P0304, P0305, P0307, P0310, P0311) against the physical motor nameplate.

3. 3

   3. Set P0300 (Motor type) to the correct value (e.g., 1 for asynchronous motor, 2 for synchronous motor).

4. 4

   4. Perform a motor identification run (P0340 = 1 or P0340 = 2), ensuring the motor is uncoupled if necessary.

5. 5

   5. Check encoder parameters (P0408, P0410) for correct settings if an encoder is used and the fault persists.
