Page 4: Introduction
Introduction This document has to be read before startup the device first time. Otherwise damage on the device and external connected devices can occur. The signal names in squared brackets ([ ]) are the references to the CAN-matrix. List of abbreviations ... -
Page 5: Uhs-Main-Regulator
UHS-main-regulator The main-regulator regulates the high-side-voltage. For a functional operation, the following CAN-messages have to be set correctly: [SG_Sollwert]: Value of the commanded high-side voltage. (Sollwert engl.: desired value) [SG_HR_Mode_Check]: Interpretation of the internal current measurement Boostmode Direction of current from LS to HS. ... -
Page 6: Regulator Priorities
Due to measurement tolerances a parametrization of the current regulators to zero in order to avoid a change of operating direction may cause problems (especially at no load conditions). Therefore BRUSA recommends to set the current regulators to MIN_CURRENT_LIM, whereby |MIN_CURRENT_LIM| ≥ 2A. -

Page 10: Condition Uhs_Com < Uhs_Min
Condition UHS_COM < UHS_MIN Device in boostmode: BDC regulates UHS_MIN. Device in buckmode: BDC regulates UHS_COM till UHS < UHS_MIN. Then the BDC regulates on UHS_MIN as well. Condition UHS_COM > UHS_MAX Device in buckmode: BDC regulates UHS_MAX. ... -
