5.3.4 Control parameter sets
For the HS5E, you have the option of configuring and using up to four different
parameter sets. Using these parameter sets, it is possible to optimize the control
behavior of the HS5E to different connected oil volumes.
5.3.5 Special operating modes
In this chapter, we will describe specific applications. In these cases, the basic
operating modes are active (see page 24).
To start up the HS5E systems, it is not necessary to provide hydraulic circuitry for
classical depressurized start-up.
If no command values are specified for the pressure and swivel angle, virtually load-
free start-up is possible.
Operating mode of the pump in which the system statically regulates an operating
point by means of a corresponding command value. Pay attention to the information
about permissible pressures in chapter 5.3.6 “Working pressure limits/external pilot
oil” (page 27).
Operating mode of the pump with reference to the lowest achievable swivel angle,
which does not generally come about on its own if active control is not active.
If the drive enable is canceled, the electronics regulate to the specified internal
command value (factory setting is 10% α
