1.1 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 (EWMPC/20 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.

1.2 Characteristics
This electronic module was developed for controlling the position and/or pressure of a hydraulic
axis via the integrated ProfiNet fieldbus interface.
The hydraulic axis can be driven as positioning control with digital stroke measuring (SSI interface)
or by analogue sensors.
Additionally, an integrated pressure limitation control function for one or two pressure sensors
(differential pressure) is implemented. Command signals and actual values are transmitted by a
ProfiNet communication interface. Feedback are status information and actual values.
Proportional valves with integrated electronics (typically control valves) can be driven by the
analogue output.
Internal failure and the system statuses are monitored. The ready output is available as a fieldbus
information and parallel as a hardware output.
The parameterization is performed via a USB interface in combination with our PC program
EWMPC/20. Alternatively, defined parameters can be modified via the ProfiNet interface.
Typical applications: general positioning drives, fast transport drives, handling systems, speed-
controlled axes and presses with positioning and pressure control.
Features
•ProfiNet for command values, sensor values, control word and status word
•SSI- or analogue feedback sensors (0… 10 V or 4… 20 mA)
•Resolution up to 1 µm (SSI - interface)
•Speed resolution 0,005 mm/s
•Positioning modes are: stroke-dependent deceleration or NC mode with internal profile
generator
•Profiling of the movement with two positions and two speeds
•Alternatively continuous command signal transition
•Differential pressure limitation control or direct pressure control
•Expanded closed loop control functions:
•PT1 filter
•Drift compensation for optimal zero-point adjustment
•Accurate positioning by compensation of force depended positioning deviations
•Feed forward to reduce the following error
•Acceleration feedback by measuring the differential pressure (used to improve the dynamic
behavior in case of low dynamics drives)
•Optional: with integrated start-up assistant
•Usable with overlapped proportional valves and with zero lapped control valves
•Fault diagnosis and extended function checking
•Simplified parameterization with EWMPC/20 software

2Use and application
2.1 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 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.

2.3 Method of operation
This module is a combined system of position control and pressure control. The standard
communication via fieldbus simplifies the wiring. The EWM-SP-DAD can be used as a universal axis
controller for hydraulic drives. Because of a second position and a second velocity, it is optionally
possible to drive to target position with the corresponding speed (rapid traverse and creeping
speed respectively creeping speed and rapid traverse)
Positioning: the axis can be used as point to point controller (stroke depended deceleration) as
well as in NC mode. With only a few parameters the controller can be optimized, the movement
profile is preset via Fieldbus (position and velocity).
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 2 is not equal
to zero. The following features have to be noticed:
•The target position is command value P2 combined with velocity V2.
•The position with the position setpoint 1 is the switching position that is approached with
speed 1 and then switches to speed. 2
•The switch from a low to a high velocity is performed at position setpoint 1 on the
acceleration ramp, see below.
•If the positioning command value P2 is between the actual and the command value position
P1, position P2 can only be driven with speed V1.
