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 a requirement that no
strong electro-magnetic interference sources are installed nearby when using our control and regulation modules.
Typical installation location: 24V 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 space close to the PLC (24 V area) is most suitable. All digital
and analogue inputs and outputs are fitted with filters and surge protection 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- connected
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 shielded.
All other cables must be screened if there are powerful interference sources (frequency
converters, power contactors) and cable lengths > 3m. 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 possi-
ble. 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.
With 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).
Particular care is required with cables of over 40 m in length – the manufacturer should
be consulted if necessary.
A low-resistance connection between PE and the mounting rail should be provided. Transient inter-
ference 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
IEC364-4-4, 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 connected to the same power supply) must
always be provided with appropriate overvoltage protection directly at the coil.

3.2 Typical system structure
This minimal system consists of the following components:
(*1) Proportional valve with OBE
(*2) Hydraulic cylinder
(*3) Position sensor
(*4) POS-124-U-PFN control module
(*5) interface to PLC with analogue and digital signals
3.3 Method of operation
This control module supports simple point-to-point positioning with hydraulic drives. The system works based
on the principle of stroke-dependent deceleration, i.e. the control gain (deceleration stroke) is set via parameters D:A and D:B. Alternatively it can also function in NC-Modus by setting the loop gain parameters. In this
mode the drive will move with controlled velocity to the target position.
The deceleration characteristics can be set linearly (LIN) or approximately quadratically (SQRT1) via the
CTRL parameter. For normal proportional valves SQRT1 is the input setting.
For control valves with a linear flow curve it depends on the application. If LIN is selected for these valves a
significantly shorter deceleration distance can often be set (D:A and D:B).

Positioning sequence:
The positioning is controlled via Fieldbus. After switching on ENABLE input, the command position (or target
position) is set equal to the actual position of the sensor and the axis stays in closed loop position control
mode. The READY output indicates that the system is generally ready for operation. After setting the
START-signal, the preset command value will be taken over. The axis immediately will drive to this new command position and indicates reaching it by setting the InPos output.
The Poswin output stays active as long as the axis is within the preset Poswin window and the START input
is active. The driving velocity is regulated by preset parameter, too.
The axis can be driven in manual mode (START is off) using the control bits HAND+ or HAND-. The velocity
is programmable. When the HAND signal is deactivated, the command position is set to the actual position
and the system stays in closed loop position control mode.
Setting the synchronous bit (GL) will synchronize both axes and the synchronization controller is overriding
the position controller of axes 2. Axes 2 is now following axes 1 according to the master-slave-principle.
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 with our modules a
resolution of < 0.01% only needs to be considered with long positions. In addition, the linearity of the individual signal points (PLC, sensor and control module) must be considered. The worst-case scenario is that a
system-specific absolute fault occurs.
The repeat accuracy is, however, not affected by this.

Step
Task
Installation
Install the device in accordance with the circuit diagram. Ensure it is wired correctly 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 device. If
it is higher than specified there is an error in the wiring. Switch the device 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.
Further commissioning and diagnosis are supported by the operating software.
Pre-parameterisation
Now set up the following parameters (with reference to the system design and circuit diagrams):
SYSRANGE, SENSOR SETTINGS, POLARITY, ACCELERATION and
DECELERATION.
Pre-parameterisation is necessary to minimise the risk of uncontrolled movements.
Parameterise specific settings for the control element (MIN for following error
compensation and MAX for maximum velocity).
Reduce the speed limitation to a value which is uncritical for the application.
Control signals
Check the control signal with a voltmeter. The control signals (PIN 15 to PIN16
and PIN19 to PIN20) lies in the range of ± 10V. In the current state it should show
0V. Alternatively, if current signals are used, approx. 0 mA should flow.
CAUTION! This signal depends on the EOUT setting.
Profibus communication
Activate the profibus communication and check whether the right values and bits
are send to the module.
Switching on the
hydraulics
The hydraulics can now be switched on. The module is not yet generating a
signal. Drives should be at a standstill or drift slightly (leave its position at a slow
speed).
Activating ENABLE
CAUTION! Drives can now leave their position and move to an end position at full
speed. Take safety measures to prevent personal injury and damage.
Drives stay 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.
Activating START
With the start signal the demand value on 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.
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.
Optimize controller
Now optimize the controller parameters according to your application and your requirements.
