Parameter
[Direct access]
Use VVVF
[CMD-> 7061-> OK]
Selection whether a frequency-controlled
hydraulics governor is used. Press > to go to
pages with frequency-controlled VVVF.
Change to sub-menu page 61 which serves to
set various parameters of a frequency-
controlled hydraulics system. For further
information regarding this submenu, check
the corresponding chapter.
When the time span for the valve overrun is
set to 0, both pump motor and valves switch
off simultaneously. For valve overrun larger
than 0, and given the pump motor’s
contactor is switched off during upward
travel, the valve remains open for the time
span indicated in “t: valve overrun”
(milliseconds). Only after that, the valve
closes.
Note the following: The subsequently given
pump overrun parameters are deactivated
when a value for the valve overrun is set. In
the event of a downward travel, there exists
no valve overrun.
Serves to select which output or relay creates
the motor overrun (pump overrun). A relay
contact is located in the valves control circuit
which makes sure that they are switched off
before the pump by the overrun time.
If this parameter is assigned with an
addressing, the following 3 parameters must
also be programmed.
Time span during upward travel
(milliseconds) which indicates by how much
the valves close earlier than the contactors
switch off.
Serves to select whether the pump overrun is
switched on during downward travel. When
travelling down, an activated overrun leads
the valves to close before the contactors are
deactivated; resulting in a smooth stop.
t: Motor run on-Down
(ms)
Time span during downward travel
(milliseconds) which indicates how earlier the
valves close than the contactors switch off.
Selection which output serves to issue the
intermediate speed V1.
If this parameter is assigned with an
addressing, the following 2 parameters must
be programmed.
