2 Characteristics
This electronic module has been developed for controlling hydraulic positioning drives. The demands are
given via Profinet. Proportional valves with up to 2.6 Ampere nominal current can be controlled directly. The
advantage of the integrated power output stage is based on the integrated control behavior without additional
dead times. The setpoint is specified via a Profinet interface, the position feedback of the cylinder is read in as
an analog signal.
The position controller is optimized for stroke-dependent deceleration or the NC control mode. The controller
and the controller settings are adapted to typical requirements and thus permit rapid and uncritical optimization
of the control behavior. The optimized control function offers a high degree of precision together with high
stability for hydraulic drives. The movement cycle is controlled via the external position and speed demands in
SDD mode or via the internal profile generator in NC mode.
Our start-up tool WPC-300 supports the parameterising and trouble shooting. The fieldbus interface provides a
continuous monitoring of actual values and operating states. Control parameters can also be changed via
Profinet.
Typical applications: general positioning drives, fast transport drives, handling systems, speed-controlled
axes and also tracer control.
Features
•Control via Profinet interface
•Analog free scalable sensor input
•Real physical units like mm or mm/s
•Principle of stroke-dependent deceleration for fast and robust positioning
•NC profile generator for constant speed
•Application oriented parameterising
•Controlling and monitoring via fieldbus
•Integrated power stage
•Individual profile demand by speed, acceleration and delay
•Fault diagnosis and extended function checking
•Simplified parameterisation with WPC-300 software

3 Use and application
3.1 Installation instructions
•This module is designed for installation in a shielded EMC housing (control cabinet). All cables which
lead outside must be screened; complete screening is required. It is also necessary to avoid strong
electro-magnetic interference sources being installed nearby when using our open and closed loop
control modules.
•Typical installation location: 24 V control signal area (close to PLC)
The devices must be arranged in the control cabinet so that the power section and the signal section
are separate from each other.
Experience shows that the installation place close to the PLC (24 V area) is most suitable. All digital
and analogue inputs and outputs are fitted with filters and surge absorbers in the device.
•The module should be installed and wired in accordance with the documentation bearing in mind EMC
principles. If other consumers are operated with the same power supply, a star-shaped ground wiring
scheme is recommended. The following points must be observed when wiring:
•The signal cables must be laid separately from power cables.
•Analogue signal cables must be screened.
•All other cables must be screened if there are powerful interference sources (frequency
converters, power contactors) and cable lengths > 3 m. Inexpensive SMD ferrites can be
used with high-frequency radiation.
•The screening should be connected to PE (PE terminal) as close to the module as
possible. The local requirements for screening must be taken into account in all cases. The
screening should be connected to at both ends. Equipotential bonding must be provided
where there are differences between the connected electrical components.
•If having longer lengths of cable (> 10 m), the diameters and screening measures should
be checked by specialists (e. g. for possible interference, noise sources and voltage drop).
Special care is required if using cables of over 40 m in length, and if necessary the
manufacturer should be consulted if necessary.
•A low-resistance connection between PE and the mounting rail should be provided. Transient
interference is transmitted from the module directly to the mounting rail and from there to the local
earth.
•Power should be supplied by a regulated power supply unit (typically a PELV system complying with
IEC 60364-4-41 / VDE 0100-410, secure low voltage). The low internal resistance of regulated power
supplies gives better interference voltage dissipation, which improves the signal quality of high-
resolution sensors in particular. Switched inductances (relays and valve coils) which are connected to
the same power supply must always be provided with appropriate overvoltage protection directly at the
coil.

3.2 Method of operation
This control module supports simple point-to-point positioning with hydraulic drives. The system works on the
principle of stroke-dependent deceleration, i. e. the control gain (deceleration stroke) is set via parameters D:A
and D:B. Alternatively the loop gain V0:A and V0:B will be used in NC mode. In this mode the velocity is
controlled and the profile ist defined by the velocity and the acceleration.
The deceleration characteristics can be set linearly (LIN) or approximately quadratically (SQRT1) via the
CTRL parameter. For normal proportional valves SQRT1 is the standard setting. In NC mode normally the LIN
variation is the better fitting one.
3.2.1 Positioning sequence
The positioning procedure is controlled by the switching inputs. After the ENABLE signal is applied, the
required position equal to the actual position is set in the module and the drive remains stationary under
control at the current position. The general readiness for operation is now reported via the READY output. The
START signal activates the transmitted position setpoint. This happens either only on the rising edge of the
START signal or continuously if the DIRECT control bit is set.
The drive moves directly to the new required position and reports the reached position via the InPos output.
The InPos output remains active as long as the position is maintained and as long as the START signal
remains applied.
In manual mode (START disabled) the drive can be moved by means of HAND+ or HAND-. The drive moves
under open-loop control at the programmed manual speeds.
When the HAND (+ or -) signal is switched off, the current actual position is accepted as the required position
and the drive comes to a controlled stop.
The HAND mode can be used-in case of a sensor failure-to drive the axis manually.

3.2.2 Influences on positioning accuracy
The positioning accuracy is determined by the hydraulic and mechanical conditions. The right choice of valve
is therefore a decisive factor. In addition, two mutually contradictory requirements (short position time and high
accuracy) must be taken into account when designing the system.
The electronic limitations lie mainly in the resolution of the analogue signals, although a resolution of
< 0,01 % only needs to be considered for our modules with long positions. In addition, the linearity of the
individual signal points (PLC, sensor and control module) must be taken into account.
It is generally recomended to calculate the static and dynamic behavior of the hydraulic axis. For supporting
this, following technical basic data are required:
- minimum natural frequency of the cylinder,
- maximum theoretical speed for extending and retracting,
- valve characteristics (natural frequency, overlapping, hysteresis and the flow gain (flow and pressure
drop),
- system pressure, maximum pump flow,
- and a description of the general system requirements.
3.2.3 Optional additional function: motion profile with second speed
Because of the input of a second position and speed, the axis can be driven to this position with the second
velocity. This mode is only activated when the velocity command value V2 is not equal to zero.
The following features have to be noticed:
•The position command value (P2) is the end position that is approached with the velocity (V2).
•The position setpoint (P1) is the switching position, which is approached with the speed (V1) and then
switched over to the speed (V2).
•The speed is switched via the speed ramp (in NC mode via the acceleration).
•If the position setpoint (P2) is between the feedback value and the position setpoint (P1) (P1 and P2 are
reversed), the position (P2) is started at speed (V1).
The following illustrations show two possible speed profiles, which result depending on the choice of speed V2
in relation to V1:

3.3 Commissioning
Step
Task
Installation
Install the device in accordance with the circuit diagram. Ensure it is wired cor-
rectly and that the signals are well shielded. The device must be installed in a
protective housing (control cabinet or similar).
Switching on for the first time
Ensure that no unwanted movement is possible in the drive (e. g. switch off the
hydraulics). Connect an ammeter and check the current consumed by the de-
vice. If it is higher than specified, there is an error in the wiring. Switch the de-
vice off immediately and check the wiring.
Setting up communication
Once the power input is correct the PC (notebook) should be connected to the
serial interface. Please see the WPC-300 program documentation for how to
set up communication.
The operating software supports further commissioning and diagnosis.
Afterwards the fieldbus communication can be established. For defining the
interface the relating GSDML file should be provided to the fieldbus master
Pre-parameterisation
Now set up the following parameters (with reference to the system design and
circuit diagrams):
The SYS_RANGE, SENSOR SETTING, OUTPUTSIGNAL, ACCELERATION
and DECELERATION.
Pre-parameterisation is necessary to minimize the risk of uncontrolled
movements.
Parameterize specific settings for the control element (MIN for deadzone
compensation and MAX for maximum velocity).
Reduce the speed demand to a value which is uncritical for the application.
Control signal
Check the control signal to the valve. At the current state no current should
flow to the solenoids.
Switching on the hydraulics
The hydraulics can now be switched on. The module is not yet generating a
signal, means there should no (unwanted) reaction occur.
Activating ENABLE
CAUTION! The drive can now leave its position and move to an end position at
full speed. Take safety measures to prevent personal injury and damage.
The drive stays in the current position (with ENABLE the actual position is
accepted as the required position). If the drive moves to an end position, the
polarity is probably wrong.
Manual (HAND) operation
If START is disabled, the axis can be moved manually with HAND+ or
HAND-. After disabling the HAND signal, the axis stops in a controlled
manner at the current position.
Activating
START
With the start signal the demand value of the analogue demand value input is
accepted and the axis moves to the predefined target position.
If START is disabled, the axis stops in the preset deceleration distance D:S.
Controller optimization
Now optimize the control parameters according to your application and its
requirements.
