Drive speed Maximum is out of range
ABB · ACS850 Standard Program Firmware
Hva betyr 10042 ?
The motor's commanded velocity has exceeded the value set in the `DRIVESPEEDMAX(0)` parameter. This indicates that the drive is attempting to operate the motor beyond its configured maximum speed limit, potentially causing instability, fault trips, or premature wear on mechanical components.
Vanlige årsaker
- The DRIVESPEEDMAX(0) parameter (e.g., P1-05) is set too low for the application's required operating speed range.
- External speed command (e.g., analog input on terminal AI1, fieldbus command through P8-01) is requesting a velocity higher than P1-05.
- Speed scaling factor (e.g., P4-01 for analog input, P4-02 for keypad reference) is incorrectly configured, resulting in an amplified speed command.
- Motor encoder feedback resolution parameter (e.g., P5-01, P5-02) is misconfigured, causing the drive to misinterpret the actual speed.
- Run-time velocity profile or positioning block is attempting to execute a move with a target speed greater than P1-05.

- 1
Increase the DRIVESPEEDMAX(0) parameter (e.g., P1-05) to a value equal to or greater than the maximum required operating speed for the application.
- 2
Verify the scaling of the external speed command input (e.g., P4-01 for analog input scaling) to ensure it aligns with the desired speed range.
- 3
Check the current speed command value (e.g., P0-01) against the set DRIVESPEEDMAX(0) parameter in the drive's monitor menu.
- 4
Adjust the acceleration/deceleration ramps (e.g., P3-01, P3-02) to prevent overshooting the target speed during rapid changes.
- 5
Review the programmed motion profile (if applicable) to ensure all target velocities are within the allowed DRIVESPEEDMAX(0) limit.
- 6
Confirm the motor nominal speed and maximum speed (from nameplate) are correctly entered in motor data parameters (e.g., P2-04, P2-09).
