[ 0 ]
Selection of the parameter set you want to work with. Four parameter sets are available. Each pa-
rameter the setting of which does not extend to the other parameters is marked
P
.
The parameter set which is to be used for operation is activated via a digital input or as a result of a
bus-transmitted command. Parameter sets may be switched in the course of operation (on-line).

If the inverter is enabled via the keyboard (ControlBox, PotentiometerBox or ParameterBox), the set
of operating parameters made available will be the one selected in P100.

P102
Acceleration time
P
Always available
0 ... 320.00 s
[ 2.00 ]
or [ 3.00 ]
Acceleration time is understood to be the time required for the frequency to rise from 0Hz to the
maximum frequency set in P105 following a linear ramp. If a current setpoint <100% is used, ramp-
ing up will take less time depending on which setpoint has been adjusted.
Under certain circumstances acceleration may take longer than provided for by the setting, e.g. as a
result of inverter overload, setpoint delay, ramp smoothing, or when the current limit has been
reached.
P103
Deceleration time
P
Always available
0 ... 320.00 s
[ 2.00 ]
or [ 3.00 ]
Deceleration time is understood to be the time required for the frequency to be reduced from the set
maximum frequency (P105) down to 0Hz along a linear ramp. Using a current setpoint <100% will
result in a corresponding reduction of deceleration time.
Under certain circumstances deceleration may take longer than provided for by the setting, e.g. as a
result of >Ramp smoothing< (P106) or because of the >Disconnection mode< (P108) that has been
selected.
