Drive: Incorrect control parameter

Hva betyr F07080 ?

The closed-loop control parameters have been incorrectly configured, for example, setting p0356 (L_spread) to 0. This fault prevents the drive's control algorithms from functioning correctly, potentially leading to erratic behavior or inability to operate. The fault value (r0949) indicates the specific parameter number that is incorrectly set.

• Critical control parameter (e.g., P0356 'L_spread' or P1082 'Maximum speed') set to an invalid or zero value.
• Inaccurate or incomplete motor data (P0304-P0311) entered into the drive, leading to incorrect control model calculations.
• Attempting to operate the drive with a control mode (P1300) that requires specific parameters not yet configured or valid.
• Controller gain parameters (e.g., P291, P292 for speed control) set to extreme values causing instability or inability to control.

1. 1

   Verify the value of P0356 (L_spread) is set to an appropriate non-zero value, typically derived from motor data or autotuning.

2. 2

   Perform a motor identification run (P1900=1 or P1900=2) to automatically determine and set motor control parameters.

3. 3

   Confirm all motor-related parameters (P0304-P0311) accurately match the connected motor's nameplate data.

4. 4

   Reset drive parameters to factory defaults (P0010=30, P0970=1) and then reconfigure essential operational parameters.

5. 5

   Adjust P1082 (Maximum speed) to a value consistent with the application's required speed range and motor limits.
