Installation and removal of module from the rail
Wire stripping:
Bulletin HY30-3255-INST/UK
The screw terminals are designed to connect to all
kinds of copper wires without the need for specific
preparation. To protect stripped wires the use of
end sleeves is recommended.
Mounting: 1bring the module in contact with
the upper edge of the rail
2flip the module downward until
it snaps into/on the rail
Removing: 1 use a screw driver (approx. 4 x 1 mm
blade) to lift metal socket
2 flip the module upwards and remove
it from rail
To ensure EMC compatibility, the connections partly
have to be shielded. See details in the „Electrical
Interfacing“ section.
The installation must be performed by qualified personnel only. A electrical short between
individual connectors, loose wires as well as
improper shielding can result in malfunction
of electronic or pump and in irreparable destruction of control module.
The pump has to have a direct connection to
an earth grounded machine frame. An earth
ground connection of the mounting rail and
the cable shields have to be connected to the
control unit earth ground terminal. Machine
frame and control unit must be connected
with a low resistance connection to avoid
ground loops.
Operating limits
The electronic module may be operated within the
specified limits only. Please refer to the „technical
data“ section (please refer to page 6).
Follow the environmental conditions! Extreme
temperatures, shock load, moisture, radiation, illegal electromagnetic emissions may
result in malfunction and other operating
issues. Follow the limitations listed in the
„specifications“ table
Soldering of the connecting wires is not permitted.
Electrical Interfacing
Supply Voltage
The module is connected to power supply, machine
control and to pump /valves with plug-in PIN screw
blocks.
The supply voltage has to be connected to PINs 3
and 4 and to PINs 22 and 24. The supply voltage
must be higher than 18 V to avoid sensor malfunction and lower than 30 V to avoid overheating and
destruction of the module. The residual ripple may
not exceed 5%.
Electrical Connection
This easy-to-install connection allows a fast
module replacement.
The connecting wires need to match the specification below:
Wire type: hook up cable, stranded
Cross section:
supply voltage,
solenoids:
min. AWG 16 / 1.5 mm²
sensors, commands: min. AWG 20 / 0.5 mm²
Wire length:
max. 50 m
for wire length > 50 m please consult the
factory
9
The power supply must comply with the
relevant standards (e.g. DIN EN 61 558) and
must carry a CE mark. The supply voltage
must be free of inductive surges.
Please consider the high inrush current when
selecting the power supply (see specification). Power supplies with current limiting
features may cause problems during energizing the unit.
The function of the module is blocked, when
supply voltage polarity is wrong.

Digital Inputs

Enable
Displacement command signal input
A positive voltage higher than 10 V (and < 30 V) at
PIN 8 enables the solenoid current driver circuit of
the module. The operation of the module requires
a permanent signal on PIN 8 (e.g. supply voltage).
Disconnecting the enable signal or a signal level
below 2.5 V will immediately switch off the solenoid
current. Ramp settings will not apply.
The displacement command is connected to
PIN 10.
A +10 V input command at PIN 10 brings the
pump to full displacement, when module settings
and pump size are matched and if no electronic
limitation is entered into the parameters. A 0 V
input command at PIN 10 brings the pump to dead
head (0 l/min output flow), when the pressure at
the pump outlet is 20 bar or higher.
With the MAX setting for the displacement command (Parameter: MAX:WQ), a smaller displacement than the nominal pump displacement at +10
V input command can be adjusted. A minimum
displacement at 0 V command signal can be set
with the parameter MIN:WQ.
Bulletin HY30-3255-INST/UK
The enable function is not a safety function
to avoid unwanted operation of the machine
in terms of machine safety regulations.
Enable p/Q-control
A positive signal > 10 V (and < 30 V) at PIN 7 enables the pressure control function of the module.
A signal lower than 2.5 V at PIN 7 will allow the
module to perform the displacement control of the
pump only. The p-valve solenoid current is set to
maximum. The amplifier for the pressure valve is
deactivated at TYPE F (no function with mounted
p-Q block)
If the hydraulic system is not able to maintain
a pump outlet pressure of 20 bar at pump
dead head, a pre-load valve must be installed
at the pumps outlet to maintain controllability
of the pump displacement.
To prevent malfunction and erratic control
response a high signal quality is recommended. The command signal needs to be
filtered and must be free of inductive surges
and modulations.
Incorrect signal levels will lead to erratic
control function and may damage the unit.
For correct signal levels, see the technical
date section.
It is recommended to use shielded cables
with a cross section of at least 0.5 mm² for
the input command lines to avoid interference with power lines or other sources for
electromagnetic „noise“.
Enable ramp
A positive signal > 10 V (and < 30 V) at PIN 5
enables the internal ramp generator. The module
offers an individual ramp-up and ramp-down function for displacement and pressure command. This
ramp function allows ramp settings up to 60 s. A
signal lower than 2.5 V at PIN 5 will disable the
ramp generation.
Ramp function should be used for lasting
system stability.
Please note: all input commands as well as all
output signals are referenced to the modules
0 V level at PIN 9, 11 and 31.

Digital Pump Control Module

Pressure command signal input
Horse power command signal input
The pressure command is connected to PIN 13.
A +10 V input command brings the pump to the
nominal pump pressure (350 bar for PV series
pumps), if the pressure compensator differential
setting is set in the module software and the pilot
valve is the recommended type PVACRE***35
( * represents the mounting bolt options, thread
options and the sealing options). A 0 V input command brings the pump to minimum compensating
pressure (typical differential pressure + ca. 5 bar).
The relation between input command and compensating pressure is linearized for the pressure control
(open loop, TYPE=P). With a pressure transducer
installed in the pilot circuit (at the pressure pilot
valve PVAC***35), the compensating pressure is
closed loop monitored (TYPE=Q).
With the MAX setting for the pressure command
(Parameter MAX:WP), a smaller pressure at +10 V
input command can be adjusted.
The horse power command is connected to PIN 29.
A +10 V input command allows the pump to operate
within its full power range (nominal displacement
resp. flow, 350 bar output pressure). If the module
is programmed for electronic horse power limitation
(Parameter: PL:EXT = EXT), a reduced input command at PIN 29 will result in a limitation of the pump
output flow, if the maximum power is exceeded.
The maximum pump driving power is calculated
and stored internally in the module. The overall
pump efficiency is considered in this calculation. A
second maximum or limit can be set with the power
limitation parameter (PL:PL), which can be less or
equal to the calculated value.
If the external power limitation is deactivated
(Parameter: PL:EXT = INT), the power limitation
parameter defined in (Parameter: PL:PL) acts as
boundary (only if a pressure sensor is installed).
This will keep the horse power requirement of the
pump below the commanded level.
Bulletin HY30-3255-INST/UK
To enable the pump to control pressures up
to 350 bar the displacement command
has to be at least 15%.
To prevent malfunction and erratic control
response, a high signal quality is recommended. The command signal needs to be
filtered and must be free of inductive surges
and modulations.
Incorrect signal levels will lead to erratic
control function and may damage the unit.
Please see the section technical data.
A +5 V input command signal will limit the
horse power requirement for the pump to
50% of the full nominal horse power ( i. e.
for PV028 the full corner horse power at
1,500 rpm is approx. 29,0 kW, at +5 V input
command at PIN 29 the pump input power is
limited to 14.5 kW).
Only for a constant input speed this control
maintains a certain horse power level. For
variable speed, only the max. input torque
level is controlled.
If the power limitation is active, both LED
STATUS I and STATUS II are on. The power
limitation is also shown at the monitor view
(Status Info – POWER_LIM).

Sensor signals
Displacement Transducer (cable 1)
The displacement transducer (LVDT) must be
connected to the power supply (LVDT connector
PIN 2 to +24 V), to the displacement signal input
(LVDT connector PIN 1 to module PIN 6) and to
the module 0 V (LVDT connector PIN 3 to module
PIN 9 / 11).
The displacement transducer signal is 9 V
(7.5 V at frame size 1 and 2), when the pump
is at dead head and between 7.5 and 4 V
(depending on frame size and nominal displacement) at full stroke. The connection to the displacement transducer is checked by the modules cable
break monitoring.
A sensor signal below 1 V or above 10 V will lead
to a shut off of the power amplifier stages and will
force the pump to dead head.
Lagging ring must
be installed to avoid
damage!
cable 1:
4 x 0,5 mm², shielded, max. 50 m long
connector:
round type M12 x 1; 5-PIN angled version
The LVDT connector has to be assembled
carefully to avoid the danger of a short circuit
in the connector (i.e. the exact position of the
lagging ring is to be checked). A electrical
short in the connector can cause irreparable
damage to the electronic module.
Some electronics supply companies offer prefabricated cables with the M12x1 connector
molded to the cable. These cables avoid the
risk of mis-assembly, offer a higher protection
against ingression of moisture or oil and are
available in many different length options.
Please note that the displacement signal is a
voltage signal and the voltage drop is proportional to the cable length. The length of the
cable should only be as long as necessary.

Pressure Transducer (cable 2)
A pressure transducer is needed, when the module
is set to closed loop pressure control (TYPE = Q)
or if the circuit requires a internal or external horse
power control.
The pressure transducer must be connected to the
power supply (connector PIN 3 to +24 V), to the
pressure transducer signal input (connector PIN 1
to module PIN 14) and to the module 0 V level (connector PIN 2 to module PIN 9 / 11). The pressure
transducer signal is between 4 mA ­(current signal)
at 0 bar and 20 mA at the transducers nominal pressure of 600 bar. The normal working range in case
of a PV series pump is 4...11.67 mA (0…350bar).
The connection to the pressure transducer is
checked by the modules cable break monitoring.
A current below 3 mA will lead to a shut off of the
power amplifier stages and will force the pump to
dead head.

Analog Outputs
Diagnosis displacement
PIN 15 provides an analog readout proportional for
the actual pump displacement. The signal is +10 V
at full stroke and 0,15 V at dead head and stand-by
pressure, if the LVDT adjustment is correct and the
programming of the module matches the actual
pump size and displacement. The maximum current
load to this output is 10 mA.
Diagnosis pressure
PIN 16 provides an analog readout for the actual
pressure, when a pressure transducer is installed
and the module is programmed. The signal is +10
V at nominal pressure (350 bar) and 0 V at 0 bar
pump outlet pressure. The maximum current load
to this output is 10 mA.
Reference voltage output
PIN 12 provides a stabilized +10 V reference signal,
which can be used to drive potentiometers for the
analog input signals. The maximum current load
for the reference output is 10 mA.
Digital outputs
Ready
The Ready output (PIN 1) gives information on
the module being ready to operate. A signal larger
than +10 V signals a logic 1, a signal lower than
+2 V signals a logic 0. PIN 1 has a logic 1 signal,
when all necessary sensors are attached and intact
Digital Pump Control Module
Series PQDXXA-Z10
and the Enable signal is set (logic 1 at PIN 5). The
control loop is closed under these conditions. The
Ready LED (green) is lighted.
When a sensor fault occurs (cable broken, no
sensor connected, signal out of range, or wrong
pump size selected) a logic 0 is sent. The Ready
LED starts flashing.
Status
The Status I output (PIN 2) delivers via switch
sequence information about the error category.
Memory, command, sensor and solenoid errors can
be evaluated. A signal higher than +10 V signals
a logic 1, a signal lower than +2 V signals a logic
0. The signals at PIN 2 are also shown as flash
sequence at LED Status I.
In addition the LED Status II gives information
about the error description. The switch sequence
at PIN 2 and the flash sequence at LED Status I
for the error category and the flash sequence at
LED-Status II for the error description are described
in the picture shown below.
The display of error category and error description
eases the field error diagnosis.
The activity of the horse power control is shown
via a static signal at the Status I and Status II
LED. If the total input power is within the specified
corner power, both Status LEDs are off. Status I
is a logic 0. During fast control actions both status
LEDs will flicker.

5. Programming
The Programming of the p/Q-module can be done
in an easy way. For programming the module must
be connected with the PC via a programming cable
(Ordering number PQDXXA-ZXX-Kabel).
The ProPVplus Software need to be installed
and started on the connected computer to get the
module parameterized. The program runs under
WINDOWS XP, WINDOWS VISTA, WINDOWS 7
and WINDOWS 8.
The latest version can be downloaded at:
http://www.parker.com/pmde  Support
 Customer Toolbox
The PQDXXA-Z10 module is compatible to
ProPVplus 3.5.0 upwards.
Please note that the data format has been
changed from since module generation
PQDXXA-Z01 .PAR to .WPC. Old .PAR parameter sets cannot be translated to the new
data format.
The software offers the following features:
The PARAMETER LIST
displays all available
and changeable parameters. Two different input
levels are available (MODE = STD or EXP). An
input dialog opens after double clicking on the
parameter. Limits of the input are shown, faulty or
wrong inputs are identified.
All parameters are directly sent to the module, if it
is in active mode, which means ProPVplus is connected with the module [CONNECT
].
Parameter sets can also be edited offline without
any connection to the module.
The MONITOR
window allows the numerically
display of various process parameters.
The OSCILLOSCOPE
displays various process parameters as graphs. Furthermore the oscilloscope offers a Start-Stop option and allows the
data export as well as the storage as text file (.txt).
The cursor function in the right mouse button menu
provides the option for amplitude and time measurements. Screenshots can also be captured with
the right mouse button dialog.
Please see the documentation in the software
ProPVplus under MenuHelp for further
information about the handling of ProPVplus.

The Linearization is only active at TYPE P. Due to pressure valves hysteresis only ascending or
descending pressure functions can be optimized.
P_SENSOR (Pressure sensor end range):
Setting of pressure sensor end range in bar. This parameter is base for the scaling of the sensor with
the parameter P_NOMINAL.
P_SENSOR is by default set to 600 bar.
For the control options UDM, UDF, UDQ (old: UPM, UPF, UPQ) the 600 bar sensor
(PVACMS, SCP01-600-24-06) is used as standard.
P_NOMINAL (Pressure sensor scaling):
Setting of pressure sensor scaling in bar. This parameter determines the upper limit for the pressure
sensor signal.
Changing this parameter may cause negative effects to your system. A new adjustment of the
pressure valve solenoid limitation (Parameter CP:MINV and CP:MAXV) might be necessary!
In case of running the pump with a PVACRE***42 as pilot pressure valve, this parameter has to
be set to 420 bar. A new adjustment of the pressure valve solenoid limitation (Parameter CP:MINV
and CP:MAXV) might be necessary!
The parameter P:NOMINAL shall match the pressure pilots end range.
P_CORR (differential pressure setting, compensator):
Setting of the differential pressure in bar.
The factory standard setting of the compensator differential pressure is 15 bar.
P_CORR needs to be adjusted to 0 bar in case of installing the pressure transducer in the pumps
outlet.
The differential pressure is a numerical constant, which is added to the sensor pressure signal all
of the time. If the pump acts in displacement control, the constant is added as well. The system
pressure equals in this case actual pressure (XP) minus P_CORR.

The setting in PL:PL is getting active as horse power limitation.
EXTThe horse power control gets dynamic by an analog 0...10 V Signal at PIN 29 while the
setting at PL:PL gets 100% (maximum value) for the scaling.
The horse power control is only active if a pressure sensor is installed.
PL:RPM (Rotational speed setting):
Setting of the pumps or drive motors rotational speed respectively.
The parameter is used for the calculation of the maximum input power.
PL:T1 (Setting of the horse power controls delay element):
Setting the horse power controls delay element. The time between signal input and signal processing
of the horse power controlled subsystem can be modified with that parameter.
This parameter should be changed only if the controlled system tends to have instabilities due to
high dynamic challenges.
When the module is operated in horse power control mode under certain conditions and at fast
pressure rise rates the power limiter may act too slowly and the horse power requirements exceed
the limits briefly.

TS (Sample Time)
The sample time (in 100 µs) describes how often the signals is processed internally. The parameter TS
represents the controls cycle time and therewith controls dynamic.
Changes should be performed only if enough knowledge about the dynamic system behaviour
is available. Changing TS requires that all time depended parameters need to be checked and
possibly readjusted.
PMODE (Closed Loop Control Functions)
The closed loop pressure control can be driven with the MR control or with the PID control.
Currently only the PID control is supported.
PL:EFF (Mechanical Pump Efficiency)
Mechanical pump efficiency in 0,01%.
PL:EFF is used for the calculation of the corner power and therewith the maximum of parameter
PL:PL.
PL : PLMAX =
(PVSEL) • (PL : RPM) • (P_NOMINAL)
[0.1 kW]
(PL : EFF) • 6
CQ:FF (Offset - Displacement Control Valve)
Offset parameter (in 0,01%) to adjust the displacements control valve neutral point.
The Offset parameter is only needed for valves with one solenoid. The parameter needs to set to
0 in case of using a valve with two solenoids .
In a control situation, the solenoid should draw approx. 60 % of its nominal current (nominal current
1,3 A; current in control situation 780 mA). Under these conditions the solenoid provides approx.
50 % of its nominal force. That leads to a similar response for on- and off stroking.
CQ:I_LIM (Integrator Limitation)
Integrator limitation of the closed loop displacement control in 0,01%.
The integrator compensates the systems nonlinearities only. Therefore this parameter should be
chosen as small as possible.
Typical value = 2500 (25 %). Depending on systems linearity this value can also be higher.

CQ:IC (Integrator Activation)
Integrator activation of the closed loop displacement control in 0,01% (of full scale).
This parameter works as threshold value for the integrator activation (Q-PID controller). If the actual
pressure value is higher than the command value, the integrator freezes. If the actual pressure
value falls below the programmed threshold between command and actual value, the integrator
is enabled again.
This function shuts down with CQ:IC = 0. In this case, the integrator is active all time.
CP:FF (Offset Pressure Control Valve)
Offset parameter (in 0,01%) to open the valve controlled.
This Typical value = 8000…9000.
CP:I_LIM (Integrator Limitation)
Integrator limitation of the closed loop pressure control in 0,01%.
The integrator compensates the systems nonlinearities only. Therefore this parameter should be
chosen as small as possible.
Typical value = 2500 (25 %). Depending on systems linearity this value can also be higher.
CP:IC (Integrator Activation)
Integrator activation of the closed loop pressure control in 0,01%.
The Integrator gets activated within these limits (in % of full scale). This reduces the overshoot
while starting the closed loop control.
Typical value = 500…5000.
This function shuts down with CQ:IC = 0. In this case, the integrator is active all time.
MR:T1 (system time constant)
System time constant in 0,1 ms (typical = 0,5 T2) in 0,1 ms.
MR:T2 (system time constant)
System time constant in 0,1 ms.
MR:T1 and MR:T2 are parameters for the MR control. Currently only the PID control is supported.
DFREQ:Q (Dither Frequency)
Dither frequency of the displacement control valve in Hz.
DAMPL:Q (Dither Amplitude)
Dither amplitude of the displacement control valve in 0,01% of the current.
The Dither can be set with Dither amplitude and Dither frequency.
The below mentioned value for Dither amplitude and frequency should not be changed
when using a PVCMD1FB*** or a PVCM*PV**!
DFREQ:Q = 120
DAMPL:Q = 400

6.4 PID Parameter Setting
Displacement and pressure control have separate control loops, whose parameters need to be set
separately. The pressure control should be focused on, since the system behaviour is depending on
hydraulic capacities, the way of piping to the hydraulic load and the varying hydraulic working points.
The displacement control should only be tuned again in case of system instabilities.
The parameter of proportional-, integral and differential action should be adjusted in the ranges shown
below. The setting for the pressure control can also be beyond these points depending on the system.

Depending on hydraulic system!
Proportional to the pump displacement.
Only linearity errors of the displacement valve are compensated.
Bigger displacements can be parameterized with smaller I-gain without
getting system stability into jeopardy.
Recommendation for the PID parameter setting:
Preparations:
•Set P action to small value.
•Set I action to very high value.
•Set D action to zero.
PID Setting:
• Increase P until a acceptable command response is achieved.
• Decrease I until a acceptable error between command and actual value is achieved.
• Increase D until a acceptable dynamic and acceptable ripple is achieved in the command response.

Typical Step Responses:
Actual value nears only slow to the command value:
 Increase P action, if this improves, decrease I, iterate possibly.
Actual value nears only slow and with small oscillations to the command value:
 Increase P action, if this improves, decrease D action, iterate possibly.
Actual value nears only without overshoot to the actual value:
 Increase P action to get a faster response in the actual value.
Actual value nears with small overshoots to the command value:
 Optimal system behaviour
 If no overshoots are not allowed, reduce P action
Actual value nears with fast to the command value but overshoots are to big
 Decrease P action, if this improves, increase I action, iterate possibly.
