# ID 70376

Spindle speed monitoring: Maximum permissible speed exceeded.
Description | The actual spindle speed exceeds the parameterised maximum speed by at least 10%. Spindle speed is automatically limited to the maximum speed set in the tool data so this error message should never occur. Possible causes:

- Incorrect configuration of velocity scaling either in the controller or in the drive.
- Malfunction in the drive.
- Insufficient parameter setting of speed or position control loop causing overshoot in the actual speed by more than 10%.

Response | Class | 5 | Stop axis.
Solution | Class | 6 |
Parameter | %1: | Logical axis number [-]
Log. axis number (see P-AXIS-00016).
%2: | Current value [1µm/s or 0.001°/s]
Current actual axis speed.
%3: | Upper limit value [1µm/s or 0.001°/s]
Maximum permissible axis speed.
%4: | Current value [-]
Current actual axis speed in increments per cycle.
Error type | 11, Error message from position controller.
