Parameter Setting value / Description / Note
Parameter
set
Available in Option
P100 Parameter set Always visible
0 ... 3
[ 0 ] Selection of the parameters sets to be parameterised. 4 parameter sets are available. All parameter
set-dependent parameters are identified by P.
The selection of the operating parameter set is performed via a digital input or the Bus control.
Switching can take place during operation (online).

If enabled via the keyboard (ControlBox, PotentiometerBox or ParameterBox), the operating
parameter set will match the settings in P100.
P101 Copy parameter set Always visible
0 ... 4
[ 0 ] After confirmation with the ENTER key, a copy of the parameter set selected in P100 >Parameter
set< is written to the parameter set dependent on the value selected here
0 = Do not copy
1 = Copies the active parameter set to parameter set 1
2 = Copies the active parameter set to parameter set 2
3 = Copies the active parameter set to parameter set 3
4 = Copies the active parameter set to parameter set 4
P102 Start-up time P Always visible
0 ... 320.00 s
[ 2.00 ]
or [ 3.00 ] The start-up time is the time corresponding to the linear frequency rise from 0Hz to the set maximum
frequency (P105). If an actual setpoint of <100% is being used, the acceleration time is reduced
linearly according to the setpoint which is set.
The start-up time can be extended by certain circumstances, e.g. FI overload, setpoint lag, rounding
or if the current limit is reached.
P103 Braking time P Always visible
0 ... 320.00 s
[ 2.00 ]
or [ 3.00 ] The braking time is the time corresponding to the linear frequency reduction from the set maximum
frequency to 0Hz (P105). If an actual setpoint <100% is being used, the braking time reduces
accordingly.
The braking time can be extended by certain circumstances, e.g. by the selected >Switch-off mode<
(P108) or >Ramp smoothing< (P106).
