5.1.2 Basic parameters
Parameter Setting value / Description / Note 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 done 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.

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 = Results in no action.

P102 (P) Acceleration time always visible
0 ... 320.00 s
[ 2.00 ]
> 11kW [ 3.00 ]
> 22kW [ 5.00 ]
Acceleration 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 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 (P) Deceleration time always visible
0 ... 320.00 s
[ 2.00 ]
> 11kW [ 3.00 ]
> 22kW [ 5.00 ]
Deceleration 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 deceleration time reduces
accordingly.
The deceleration time can be extended by certain circumstances, e.g. by the selected >Switch-off
mode< (P108) or >Ramp smoothing< (P106).
P104 (P) Minimum frequency always visible
0.0 ... 400.0 Hz
[ 0.0 ]
The minimum frequency is the frequency supplied by the FI as soon as it is enabled and no additional
setpoint is set.
In combination with other setpoints (e.g. analog setpoint or fixed frequencies) these are added to the
set minimum frequency.
This frequency is undershot when
a) the drive is accelerated from standstill.
b) The FI is blocked. The frequency then reduces to the absolute minimum (P505) before it is
blocked.
c) The FI is reversing. The reverse in the rotation field takes place at the absolute minimum
frequency (P505).
This frequency can be continuously undershot if, during acceleration or deceleration, the function
"Maintain frequency" (Function Digital input = 9) is executed.
