1.7 Safety instructions
Please read this document and the safety instructions carefully. This document will help to define the product area of application and to put it into operation. Additional documents (WPC-300 for the start-up software) and knowledge of the application should be taken into account or be available. General regulations and laws (depending on the country: e. g. accident prevention and environmental protection) must be complied with.
These modules are designed for hydraulic applications in open or closed-loop control circuits. Uncontrolled movements can be caused by device defects (in the hydraulic module or the components), application errors and electrical faults. Work on the drive or the electronics must only be carried out whilst the equipment is switched off and not under pressure.
This handbook describes the functions and the electrical connections for this electronic assembly. All technical documents which pertain to the system must be complied with when commissioning.
This device may only be connected and put into operation by trained specialist staff. The instruction manual must be read with care. The installation instructions and the commissioning instructions must be followed. Guarantee and liability claims are invalid if the instructions are not complied with and/or in case of incorrect installation or inappropriate use.
CAUTION!
All electronic modules are manufactured to a high quality. Malfunctions due to the failure of components cannot, however, be excluded. Despite extensive testing the same also applies for the software. If these devices are deployed in safety-relevant applications, suitable external measures must be taken to guarantee the necessary safety. The same applies for faults which affect safety. No liability can be assumed for possible damage.
Further instructions
The module may only be operated in compliance with the national EMC regulations. It is
the user’s responsibility to adhere to these regulations.
The device is only intended for use in the commercial sector.
When not in use the module must be protected from the effects of the weather,
contamination and mechanical damage.
The module may not be used in an explosive environment.
To ensure adequate cooling the ventilation slots must not be covered.
The device must be disposed of in accordance with national statutory provisions.
2 Characteristics
This electronic module has been developed for controlling hydraulic positioning drives. Proportional valves with integrated or external electronics can be controlled with the differential output.
The internal profile generation 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 inputs. The high resolution of the analogue signals ensures good positioning behavior.
Alternatively, the P version is available with an integrated power output stage (see additional information: POWER OUTPUT STAGE). The advantage of the integrated power output stage is founded in the integrated control behavior without additional dead times. This allows higher dynamics and higher stability respectively.
The SSI extension is available for use with digital sensors (see additional information: SSI INTERFACE). Sensors with a resolution of one µm can be used for very high position accuracy.
Setting up this module is simple and easy to handle with our WPC-300 start-up software. Typical applications: general positioning drives, fast transport drives, handling systems, speed-controlled axes
and also tracer control.

2.2 Device description
Standard module – for the P-Version look at point 7.2
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
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) which are 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 (or control valve): the valve type determines the precision. It is expedient to use
control valves with integrated electronics. (*2) Hydraulic cylinder (*3) Integrated analogue or SSI position sensor (alternatively also with external position sensor) (*4) POS-123-* 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 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 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 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 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 analogue demand value input (PIN 13) which is accepted as the new required position. 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.

driving in
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.
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, overlapped or zero lapped, hysteresis and the flow gain (flow and pressure drop),
- system pressure, maximum pump flow,
- and a description of the general system requirements.
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-parameterization
Now set up the following parameters (with reference to the system design and circuit diagrams):
The SYS_RANGE, SENSOR SETTING, POLARITY, ACCELERATION and DECELERATION. Pre-parameterization 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 limitation (VELO command) to a value which is uncritical for the application.
Control signal
Check the control signal with a voltmeter. The control signal (PIN 15 to PIN16) lies in the range of ± 10 V. In the current state it should be 0 V. Alternatively, if current signals are used, approx. 0 mA should flow.
Switching on the hydraulics
The hydraulics can now be switched on. Since the module is not yet generating a signal, the drive should be at a standstill or drift slightly (leave its position at a slow speed).
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.
Speed demand
The speed can be limited by means of the VELO parameter or the external speed demand (VS = EXT).
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.
CAUTION! Please check the manual operation in conjunction with the EOUT command. If the EOUT is active do not use the manual operation.
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.
Optimize controller
Now optimize the control parameters according to your application and your requirements.
