Cross section min. AWG16
Outer dimension 8...12 mm
Cable length max. 50 m
For cable lengths > 50 m consult Parker.
The connection cable is coupled to the female
connector by solder joints.
The shielding has to be assembled according the
outline below.
Skinning lengths for the connecting cable:
The connection Code 5 requires a 11 + PE female
connector EN 175201-804.
The female connector has to be ordered
separately under article nr. 5004711.
In case third party connectors are used, ac-
cordance to the relevant EMC directives must
be ensured.
The connecting cable has to comply to the follow-
ing specication:
Cable type control cable, exible,
8 conductors, overall braid
shield
Cross section min. AWG16
Outer dimension 12...15 mm
Cable length max. 50 m
For cable lengths > 50 m consult factory.
The connection cable is coupled to the female
connector by crimp contacts.
The shielding has to be assembled according the
outline below.
Do not disconnect cable socket under volt-
age!
Skinning lengths for the connecting cable:
The backshell nut of the cable gland has to be
tighten with a suitable tool. The target value for
the tightening torque is 4 Nm. Tighten the cap nut
with a torque of 5 Nm after attaching the female
connector on the socket.
Incomplete tightening of backshell nut re-
spectively cap nut may result in undesired
release of the connection as well as degrada-
tion of the water tightness.
When using female connectors of other
manufacturers, the relevant regulations must
be observed.
The cable may only be connected to the
female connector by authorized and qualied
personnel. A short between individual con-
ductors resp. to the connector housing , bad
soldering as well as improper shield connec-
tion may result in malfunction and breakdown
of the valve.
The mounting surface of the valve has to be
connected to the earth grounded machine
frame. The earth ground wire from the valve
connecting cable as well as the cable shield
have to be tied to the protective earth termi-
nal within the control unit. It is necessary to
use a low ohmic potential connection be-
tween control unit and machine frame to
prevent earth loops (cross section AWG 6).

D_FP_D 5715-695 UK.indd 16.09.21
Enable input (only for Code 5 / 11+PE as well
as code 7 / 6+PE)
A signal voltage enables the actuator drive of the
valve. Continuous operation of the valve requires
a permanent voltage 5...30 V (e.g. the supply volt-
age). In case of disabling the signal the valve will
reach its power down position spring-actuated
independently from the command signal value.
The enable function represents no safety
arrangement against unwanted valve opera-
tion in terms of accident prevention regula-
tions.
Electrical interfacing
Supply voltage
The supply voltage for the valve has to cover the
range of 22...30 V. Valve is de-energized below
19 V. The residual ripple may not exceed 5 % eff.
The applied power supply must comply to
the relevant regulations (DIN EN 61558) and
must carry a CE-mark. The operating voltage
for the valve must be free of inductive
surges. Do not exceed the max. value of 30V!
Higher voltage can lead to failure of the valve.
The increased inrush current of the valve
should be considered when selecting the
power supply. A stabilized power supply with
overcurrent limiting feature should not be
used. Due to the inrush current of the valve
the current limit circuit may respond prema-
turely and create problems during energizing
of the supply voltage.
The operation of the valve is blocked if the
supply voltage polarity is interchanged.
Each valve requires a separate pre-fuse of 4
Amp semi time-lag. Failure to observe this
instruction may create irreparable damage
of valve respectively incorporated system
parts.

D_FP_D 5715-695 UK.indd 16.09.21
Command signal input
The spool stroke is proportional to the command
signal amplitude.
The command input signal needs to be ltered
as well as free of inductive surges and
modulations. Due to the sensitivity of the
valve a high signal quality is recommended.
This will prevent malfunction.
The option 4...20 mA uses the “3.6 mA“
condition as breakdown-information. If the
input signal line is interrupted, an evaluable
failure information is available. In this case
the actuator drive will be switched off. The
drive will switch on when the input signal
reaches a value of 3.8 mA, it switches off
when the command falls below 3.6 mA. This
determination follows the NAMUR-speci-
cation NE43.
Diagnostic output
A diagnostic signal is available. Its voltage repre-
sents the operating condition of the valve.
The output may drive a load of max. 5 mA.
Exceeding of this limit leads to malfunction.

Spool position at power down/center position
For valves with zero lap spools, distinction
must be made between hydraulic neutral
position and power-down position. Neutral
position is taken at neutral input signal, cor-
responding to zero position of the hydraulic
symbol. When the valve is switched off – no
supply voltage, no enable, current signal
(code S) < 3,8 mA – zero lap valves take the
power down position (approximately 10 %
opening) according to the ordering code. For
valves with overlap spools, neutral position
and power down position are the same (zero
position).
Solenoid current monitoring
If the actuator current time interval exceeds 10
seconds, the actuator is switched off to prevent
overheating. For normal operating conditions this
state will not reached, but it may occur with a
contaminated sluggish valve.
In this case the reason for the contamination
should be rectied (hydraulic uid exchange,
ltration review, valve ushing).
The overcurrent shutoff condition may be resetted
by the actions below:
Code 0: Temporary disconnection of the supply
voltage.
Code 5: Temporary disconnection of the enable
signal.
Code 7: Temporary disconnection of the enable
signal.
The shutoff of the VCD actuator due to over-
load will be indicated via the diagnostics
output.

It permits the setting of all application specic
parameters to match the valve function with the
task setting.
In case of special applications the valve parameters
may be adapted via the expert mode. The operating
mode may be selected from the “Options”- menu
and remains after terminating and re-start of the
program.
Changing of expert parameters is only permit-
ted for qualied personnel. Incorrect settings
may lead to malfunction! In case of parameter
changes shut the drive down!
To prevent an unauthorized access for the expert
mode, a password is requested. The name is
“parker” and cannot be changed. Thus additionally
to the button “Default” for loading of the default
parameters, the button “Send parameter” appears
in the “Expert”-operating mode. This button trans-
mits only the setting of one single parameter to
the connected valve. Thus a quick tuning of single
parameters is permitted during the setup.
A horizontal bar graph readout between
the communication buttons shows the data
transfer state.
Because the ProPxD program has also with-
out connection to the valve functionality, a
manual pre-selection of the parameters is
possible. After selection of the valve type via
the menu “Options” the parameters may be
set and stored for later transmission.
Note the design series while selection of the
valve!
The “File” menu provides the functions “Printer
setup”, “Print preview” and “Print”. The print pre-
view includes the option for parameter set storage
as text le (format.txt) prior to further processing.
The “Options” menu provides also the selection
of the RS232C interface port via the menu item
“Port”. Via the menu item “Load le” previously
stored parameter sets may be loaded.
Closer information can be can be displayed via
the ProPxD parametrier software.

Application: Closed loop systems for position
Introduction
The electronics uses a feedback control loop which
automatically adjusts the electrical input to the
valve amplier to move the drive to a commanded
position. At the heart of this feedback loop is a
digital controller which computes and updates the
signal output (set value output) highly dynamic. The
controller has adjustable coefcients, which must
be set by the user for the particular application.
The controller provides a extended PID control
capability plus extra features you can use to im-
prove the performance beyond the limits of PID.
Basic information for the control algorithm
Why tuning?
The controller can be used with valves that vary
greatly in ow capacity, frequency response,
saturation and deadband, with different kinds of
load, and with cylinders of any area and stroke.
The user must adjust the control coefcients for the
specic system. There are no xed sets of values
for the controller coefcients that will handle every
situation well.
The electronics utilizes a “PID” controller for its basic
control action. The name PID comes from the fact
that the controller output is the sum of three terms,
called proportional (P), integral (I) and derivative (D),
each with a user adjustable coefcient.
The user software provides therefore the param-
eters H1 (P), H17 (I) and H26 (D).
P - H1
This term provides an immediate output signal,
proportional to the error between commanded and
measured position. If this parameter is set too high,
sustained oscillations may occur. If it is set too low,
accuracy and speed of response may be poor.
By using parameter H2 the setting of the variable
is limited.
I - H17
This term causes the output to change at a rate
proportional to the error in measured position over
time (integration time), in a direction to drive the
steady state error to zero. H17 is active within a
window, which might be adjustable by parameter
H18. H18 shall be adjusted in the way that the win-
dow lies near the nal position or in the stationary
range of the drive. A too higher value of H17 causes
oscillations, in addition to which the selection of a
too lower value may result in a slow action.
By using parameter H19 the setting of the variable
can be limited.
D - H26
The D-term provides an output proportional to
the rate of change of the measured drive position.
Depending on the polarity of the parameter prex,
this term causes damping or acceleration. For hy-
draulic drives this term should be set to a low value.
By using parameter H27 lead time the rise can
be damped.
By using parameter H28 the setting of the variable
can be limited.
Simple tuning of a position control loop
Before trying anything complicated, you should
adjust the proportional gain, accessible by H1. In
many cases this coefcient will be all you need,
and you will not have to bother with any of the
other control features. If you do need the other
features, you cannot adjust them properly without
rst adjusting the P-gain. Adjusting the P-gain is
done by setting all the other control coefcients
H2-H21 as well as H23-H28 to zero and increas-
ing H1 to the highest value that does not result in
sustained oscillations of the drive position.

Guarantee of control functionality
Before the tuning of the control loop may be com-
menced, the functionality of the control circuit must
be ensured. As previously mentioned, the control-
ler compares command and feedback signal and
adjusts the electrical input to the valve amplier
to move the drive to the commanded position. To
ensure this functionality, the polarities of command
and feedback signal must be equal.
How can the functionality of the control loop
be achieved?
At rst you should set off the control loop (set pa-
rameter H24 to value 0 = open loop and transmit
to the electronic) and cause the drive via manual
control to the middle of the cylinder stroke. Af-
terwards adjust at rst the control coefcients as
described in chapter “Simple tuning of a position
control loop” (H1 at 10 %) as well as the parameter
H24 at 2 = external closed loop and transmit to the
electronic. If this results in a rapid movement of the
drive to an end position, the polarities are incorrect.
Access now the parameter H22 = feedback signal
polarity, change the value and transmit the data.
The drive should be adjustable and remain in its
position when you switch on the closed loop control
via parameter H24. Now you should preset position
commands and supervise the drive movement.
If the drive even tough is running in closed loop
mode, but the direction of the movement is not as
required, you have to change the polarities of both
command and feedback signal via the parameters
P11 and H22. After that the drive is running as
desired, you can continue with tuning of the loop.
Tuning of the closed loop control
1. Create a suitable tuning test prole – otherwise
it may be difcult for you to tell how good the
system response is. The test prole should
programmed in a way to cause the drive to
move from the start position to the required
nal position with the desired maximum ac-
celeration and velocity. In the nal position the
drive should be commanded to dwell, that will
give you enough time to watch the load position
to see if it oscillates or remains stationary. This
should be followed by returning the drive to the
start position, where the dwell in position may
also be evaluated.
2. Check once more to be sure that H17 and H26
are set to zero.
3. Adjust H1 to a low value, i.e. 10 %, and try the
system on the test prole. Observe the result
of the test. There are three possible outcomes:
• The drive oscillates continuously
Stop the system quickly. Reduce the H1-value
to ½ of the initial guess, and try again.
• The drive overshoots, but stops after one or
two oscillations.
Reduce the H1-value to ¾ of the initial guess,
and try again.
• The drive reaches the commanded position with
no overshoot.
The system is usable with the estimated value
of P-gain. You should experiment by increasing
the H1-value stepwise to see how high a value
the system will tolerate. Accuracy and response
are improved by high values, but do not allow
permanent oscillation!
You have now completed the basic tuning for
your control loop. The next step is to test the
performance of the system to whether it meets
your requirements. If not, the electronic has ad-
ditional control features you can use to improve
performance, as explained below.
