This function is used to trigger safety shutdown as quickly as possible (within about 1
second) if great speed deviations are detected, or if speed = 0 is detected in operation.
This check is made from phase Ignition On 38 through Afterburn time 70.
The degree of deviation where quick shutdown shall take place can be set via parame-
ter TolQuickShutdown:
Checking is deactivated when 100 % is entered as the tolerance value.

The motor's speed can be acquired with different types of sensors. To detect the mo-
tor's direction of rotation with a sensor, a sensor disk with angular steps of 60°, 120°
and 180° is used. The sensor disk generates pulse intervals of different length.
Speed acquisition is safety-related!
We recommend using the accessory set AGG5.310.
To enable the acquired speed to be standardized to the range of 0...100 %, the speed
that corresponds to 100 % must be parameterized (
