Switch on pressure [bar]
Switch off pressure [bar]
Function
Selection between the use of a
pressure transducer at AIN01
or pressure switches at DI-
GIN04 (switch on signal) and
DIGIN05 (switch off signal). If
the parameter is set to TRUE,
pressure switches will be used.
The parameter “device mode
for accumulator charging” is set
to TRUE, if a pressure trans-
ducer is used in accumulator
charging control (Pressure
Switch Mode = FALSE).
When the “switch on pressure”
is undershooted, the drive ac-
celerates to the max. rotation
speed.
When the “switch off pressure”
is overshooted, the drive de-
celerates to the min. rotation
speed or stops.

(error message)
Min. time between two
accumulator charging cycles.
[s]
Function
When exceeding the max.
number of too short accumu-
lator charging cycles, a warn-
ing message is generated. The
minimum time between two ac-
cumulator charging cycles can
be defined individually.
When exceeding the max.
number of too short accumu-
lator charging cycles, a warn-
ing message is generated. The
minimum time between two ac-
cumulator charging cycles can
be defined individually.
When exceeding the max.
number of too short accumu-
lator charging cycles, an error
message is generated. The
minimum time between two ac-
cumulator charging cycles can
be defined individually.
Defines the min. time between
two accumulator charging cy-
cles. If the minimum time of two
accumulator charging cycles is
undershooted, a warning or an
error message is generated.

description
Actual number of too short ac-

Resets the number of too
short accumulator charging
cycles
Function
Actual number of accumulator
charging cycles with a pause
time shorter than the specified
min. time between two accumu-
lator charging cycles.
If this parameter is set to TRUE,
the actual number of too short
accumulator charging cycles is
set to 0 and the error message
will disappear.

Function
This value sets the delta pres-
sure setpoint for LS control.
This parameter shows the ac-
tual pressure difference (p0
– pLS).
This parameter shows the ac-
tual pressure pLS at AIN02.
Defines the max. pressure for
100% input signal at ANIN02.
