The reference value for speed levels and hystereses for model deactivation are de-
pendent on the motor type:
Synchronous machine: 100% = 7.5% * rated frequency
Asynchronous machine: 100% = 2 * rated slip frequency

Example:
Asynchronous machine
(rated frequency = 50Hz, rated speed = 1450 rpm, pole-pair number = 2)
ds46 = 100%, ds47 = 20% (default values)

Model deactivation threshold: = rated slip speed * 2 * ds46 model ctrl. act. speed
level = 100 rpm
Hysterese = rated slip speed * 2 * ds47 model ctrl. act. speed hyst = 20 rpm
Model activation threshold: = Model deactivation threshold + hysterese = 100 rpm
+ 20 rpm = 120 rpm
6.2.16.1.2 Model on/off ds41 (Bit 0…2) and (Bit 3…5) = "dep. on ref./act. speed“
The model activation is a function of the setpoint speed. The model is switched
on immediately with setpoint unequal zero (independent of the setting in ds42).
The model deactivation occurs if the setpoint = zero for the time in ds42 model
ctrl. ref. speed time and for the time in ds43 model ctrl. act. speed time the actual
value is below the switch-off threshold.
With deactivation of the model in encoderless operation ((A)SCL) it is switchted to
the model replacement („low speed ctrl“ ds41 Bit 6…7).
