Test move velocity is too high

¿Qué significa 4066 ?

During velocity autotuning, the calculated test move velocity exceeds the configured `DriveSpeedMax` parameter. This indicates a mismatch between the desired tuning speed and the drive's maximum allowed operating speed, which can cause unsafe operation, tuning failures, or unexpected drive trips.

• Parameter P1-05 (DriveSpeedMax) is configured below the calculated test move velocity required for autotuning.
• Motor encoder resolution (e.g., P5-01, P5-02) is incorrectly set, leading to an overestimation of motor speed during tuning.
• Application-specific gearing or mechanical ratios are not correctly accounted for in the drive's speed scaling parameters.
• Drive's internal velocity controller gain (e.g., P7-01 Kp_vel) is excessively high, causing an overshoot during test moves.

1. 1

   Verify the DriveSpeedMax parameter (e.g., P1-05) setting against the motor's nominal speed and the application's actual maximum speed. Adjust P1-05 higher if appropriate.

2. 2

   Confirm the motor encoder resolution setting (e.g., P5-01, P5-02) accurately matches the encoder datasheet specifications.

3. 3

   Reduce the target test move velocity parameter (e.g., P2-10, P2-11) for autotuning to a value below the current DriveSpeedMax setting.

4. 4

   Monitor the motor's actual speed via drive diagnostic screen (e.g., P0-03) during a test move after parameter adjustments.

5. 5

   Temporarily increase the acceleration/deceleration ramps (e.g., P3-01, P3-02) for the tuning process to smooth speed transitions.
