Characteristics
This electronic module has been developed for controlling hydraulic positioning drives.
Both axes can be controlled independently or also be driven in synchronous mode via ProfiNet.
The differential outputs are provided for the control of proportional valves with integrated or external
electronics (with differential input). Alternatively, the output can be parameterized to 4… 20 mA. This
module is intended for the connection with analogue position sensors 0...10V or 4...20mA (scalable) or
digital SSI sensor interfaces.
The internal monitoring sends information about error and operating states via the ProfiNet to the Master
controller. The operational readiness is reported via a digital output, too.
Typical applications: Positioning control or synchronization control with hydraulic axes.
Features
•Two independent positioning axes
•Can be combined for synchronized control
•Command position value parameter, actual value response, control bytes and status bytes
via fieldbus (ProfiNet IO)
•SSI-Sensor interface or analogue sensor interface (0….10V or 4…20mA)
•Simple and user-friendly sensor scaling
•Position resolution of 0.005 mm/s
•Principle of stroke-dependent deceleration for the shortest positioning time or NC profile
generator for constant speed
•Highly accurate positioning
•Advanced position control with PT1 controller, Drift compensation and Fine positioning
•Superimposed synchronization controller with PT1 (optimal for hydraulic applications)
•Optimal use with zero lapped control valves
•Synchronization control in Master/Slave or average value mode
•Fault diagnosis and extended checking function
•Simplified parameterization with EWMPC/20 software

USE AND APPLICATION
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 required that no d
strong electro-magnetic interference sources are installed nearby when using our 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 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 > 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 considered 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
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 364-4-4* 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.

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-Mode 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. A significantly shorter
deceleration distance can often be set (D:A and D:B) for these valves if LIN is selected.
Positioning sequence:
The positioning is controlled via Fieldbus. After switching on the 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 a signal received by the fieldbus
interface. The axis moves with a limited speed according to this preset value.
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.
In order to achieve a reliable synchronous control, the maximum speed should be limited to about
70… 80 % of the possible speed. For compensating for deviations, the slave axis must have the
ability to move faster than the master axis. This control margin is necessary and has to be
considered during the system design.
