Changeover of speed limits
The changeover is controlled by means of binary signals from two F-DIs. The speed
selection status can be checked using the r9720.9/r9720.10 parameters. Parameters
r9722.9 and r9722.10 indicate the actual speed limit, bit r9722.4 must carry a "1" signal.

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).
To ensure that the drive reaches the reduced speed below the new speed limit value once
the delay time has elapsed, it must be decelerated accordingly within the delay time by
means of the higher-level motion control/setpoint channel. 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.
