It converts a ±10 V analogue reference into a regulated current output. The output polarity follows the input polarity, while the internal current loop compensates for changes in supply voltage and solenoid resistance within the operating limits.\u003c\/p\u003e\u003ch3\u003eCurrent configuration\u003c\/h3\u003e\u003cp\u003eThe E execution is supplied without a preset current value and must be configured before commissioning. Internal DIL switches select output settings from 10 to 300 mA in 10 mA increments. Load resistance limits the usable current; check the manufacturer's load\/current curves for the selected servovalve.\u003c\/p\u003e\u003ch3\u003eAdjustment and installation\u003c\/h3\u003e\u003cp\u003eDither is selectable at 100 or 250 Hz, with amplitude adjustable from 0 to 15% of nominal current. Offset adjustment is ±6.5%. Auxiliary ±10 V outputs can supply an external reference potentiometer. Hardware switches and trimmers are used for configuration.\u003c\/p\u003e\u003cp\u003eInstall inside a protective metal control cabinet and follow the manufacturer wiring instructions. Match the valve's rated current, coil resistance and connection arrangement before ordering. The internal current loop regulates electrical output; machine position or pressure control requires the appropriate external controller and feedback.\u003c\/p\u003e\u003ch3\u003eSupply and documentation\u003c\/h3\u003e\u003cp\u003eIMPEX CONNECT supplies EWM-A-SV\/11E on order.
