The changeover from a lower to a higher speed limit takes effect without any delay.
The changeover from a higher to a lower limit triggers a delay time which can be set at the
corresponding parameter (p9351 and p9551).
In order to reach the reduced speed that is below the new limit value, the drive must be
decelerated accordingly within the delay time. However, if the actual speed is higher than the
new limit value and the time has expired, an appropriate alarm with the configured stop
response will be generated.
