Technical Information
Prof 1, PVRE and PVRET Joystick
General
Application
PVRE, PVRET and Prof joysticks from Danfoss are generally used together with PVGs and PVEs, but can be
used in any application. A complete range of joysticks from the simple PVRE handle with X-Y functions to
the Prof 1 ergonomic handle with rollers and pushbuttons are available.
Mechanical Design
All handle variants share the same mechanical base to which the electronics are mounted. The mounting
flange of the joystick is an integrated part of the mechanical base, which also contains a linkage that
transfers handle movement to the electronics. The linkage also includes neutral positioning springs.
The neutral positioning springs are designed to ensure a smooth return of the handle into neutral
position. The maximum spring force is optimised to be just strong enough to keep the handle in position,
even during operation in rough terrain, without interfering with the operation of the joystick or impairing
it’s ergonomic characteristics.
Spring force8-10 N
Main Function Module
(Prop1 and Prop2)
The primary functions of the joystick are defined as its X and Y directions.
Main functions are potentiometers with integrated direction switches.
Each function has a working angle of ±18°.
Signal rangeNeutral signal
25% – 75%50%
of supply voltage
When moving the handle diagonally the maximum signal range is not available.
Connector
All joysticks come with a common 25 pin male SUB-D connector with M3 screws. (MIL - DTL - 24308)
Proportional modules have integrated direction switches. One switch is activated when the module is
moved in the A direction, the other is activated when the module is moved in the B direction.
The direction switches are used to activate the neutral position switch, and with some electronic modules
the direction switch outputs are available in the connector. (See details about electronics.)
There is a dead band in the joystick of approximately 1.5° before the direction switches are activated.
The direction switches are independant from the signal voltage
Neutral Position Switch
The neutral position switch can supply up to 3 PVEs or other devices (see electrical details), and functions
as both a power save and a safety switch.
The switch is only activated when one or more of the proportional modules are activated.
The operation of the neutral position switch is dependant on signals from the direction switches.
Danfoss recommends that the neutral position switch be used to the greatest possible extent.
When using the neutral position switch all three UDC wires as well as all three Neutral Switch wires must
be connected.
Cables
For compatibility with different applications, a selection of mating cables are available:
The Prof family of joysticks is built around a series of modules that can be combined in various ways to
create the joystick that best fits the application.
Each joystick has a base module with proportional functions (X & Y); a colour band for decoration and
identity, a handle, and depending on handle selection, a number of pushbuttons and/or proportional
functions.
Handle / Top functions
To provide optimum user comfort, a selection of handles is available. Each handle offers a choice of push
buttons and / or proportional functions positioned for ease of use and comfort.
Base module
A number of electronic modules provide various performance levels to cater for different needs in
different applications.
A professional handle for intensive operation; with a forward-leaning, curved, ergonomic shape. The
leather-like grained surface allows the palm of the hand to breathe during operation.
The Prof 1 handle can be fitted with up to seven push buttons, or up to two proportional functions with
up to five push buttons.
For location and combination of function modules see the overview.
The flush alignment between front plate and grip can’t be guaranteed, however, an inspection is made to
insure there are no air cavities.
Color Band
Colors

Red
A choice of colors is available for the band at the base of the handle.
Proportional Modules
The roller function module is a spring centred potentiometer with integrated direction switches.
Working angle: ±42°
Direction switch angle: 3.5 ±2°

Push Buttons
The handle can be fitted with up to seven independent On/Off functions.
The buttons are protected against shocks and unintentional activation by a high collar.
The electronic modules are available with four different performance levels: Basic, Standard, Extended,
and CAN-enabled.
Basic
The Basic level module is a connection platform that contains no electronics. This version offers raw
signals from function modules, proportional modules, and push buttons.
The Basic level module contains no kind of protection, amplification, neutral switches, relays, or filtering
and meets no legal specifications.
The proportional functions in the basic module are configured like this:
The value of P is 5 KΩ, R1 and R2 are 1.125 KΩ (See technical data for tolerances).
This configuration ensures that the output signal will be at least 25%-75% of the supply voltage.
Because of the output impedance of the sensors, it is recommended to use an amplifier if the application
draws more than 15 µA.
Standard
The Standard level electronic module provides amplifiers, inverting and signal relays on all proportional
outputs, and an electronic switch on all On/Off outputs.
The signal relays are controlled by the power supply in such a way that a power failure will disconnect the
output. (This will automatically send a Danfoss proportional valve to neutral position)
When used together with a Danfoss proportional valve signal inversion causes the joystick to move the
spool in the direction opposite to the default. This is equivalent to swapping the hoses on the valve
outlets.
The directional switches are not affected by the signal inversion.

Extended
The Extended level electronic module has the same configuration as the Standard level module.
Additionally it has adjustable proportional functions. The Extended level module offers the option of
individual signal adaptation (flow adjustment) and common dead-band compensation.
