2 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 electron-
ics (with differential input).
Alternatively the output can be parameterized to 4… 20 mA. This module is in-
tended 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.
