Application
dependent*
[Application dependant] This parameter allows the choice of the min. value of the custom defined readout (occurs at zero
speed). It is only possible to select a value different to 0 when selecting a linear unit in
par. 0-30
Custom Readout Unit . For Quadratic and Cubic units the minimum value will be 0.
0-32 Custom Readout Max Value

tomReadou-
tUnit*
[Application dependant] This parameter sets the max value to be shown when the speed of the motor has reached the set
value for par. 4-13
Motor Speed High Limit [RPM] or par. 4-14 Motor Speed High Limit [Hz] (depends
on setting in par. 0-02
Motor Speed Unit ).
