The terminals X1 and X2 on the Measurement Board SDCS-UCM-1 are at the main circuit potential.The board contains two resistor chains which are connected to the intermediate circuit voltage (DC). The voltage reduced by the resistor chain is connected to Measurement Board SDCS-IOE-2.The intermediate circuit DC voltage is wired to connectors X1 and X2. The positive DC busbar (+Uc) is connected to connector X1 and negative DC busbar (-Uc) to connector X2.The connection to X1 and X2 is done according to the supply voltage (AC) of the bridge according to the table below.Supply Interm. Circuit Motor Connection ConnectionVoltage/VAC Voltage Uc/VDC Voltage/VAC Bin in X1 Bin in X2830* * 690** Nominal supply voltage is higher than the nominal motor voltage. The forward bridge is controlled so that the intermediate circuit DC voltage and motor voltages are at the desired (lower) level.Nominal DC voltage in the output of the board is 7 V.
