Selection of the parameters sets to be parameterised. 2 parameter sets are available. All parameter
set-dependent parameters are identified by (P).
Display:
Parameter set 1 Parameter set 2
Switching can take place during operation (online).
If enabled via the ControlBox, the operating parameter set will match the settings in P100.
Parameter set display at the ParameterBox:
The active parameter set is shown on the display with the abbreviation 'P1' or 'P2'.

Copies the active parameter set to the inactive parameter set. The parameter set P1 or P2
displayed in the ParameterBox is the active set. 2 parameter sets are available for
switching.
Copying of parameter sets to/from the ParameterBox Æ see Chap. 4.5 “Parameters of the
ParameterBox”, P1201 – P1203.
P102 Acceleration
time
P
Always available
0 ... 99.99 s
[ 2.0 ]
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 acceleration time can be extended by certain circumstances, e.g. FI overload, setpoint lag,
ramp smoothing or if the current limit is reached.
P103 Deceleration
time
P
Always available
0 ... 99.99 s
[ 2.0 ]
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 Minimum
frequency
P
Always available
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.
P105 Maximum
frequency
P
Always available
0,1 ... 400.0 Hz
[ 50.0 ]
The frequency supplied by the FI after being enabled and once the maximum setpoint is present,
e.g. analog setpoint equivalent to P403, an appropriate fixed frequency or maximum via the
ParameterBox
.
