9. nformation 2 3 Cascading of analog inputs Analog inputs of 4 20 mA are allowing the possibility to cascade several inputs in a row With this it is possible to read the signals from one sensor into several devices at the same time Also the analog 4 20 mA inputs at the MSD Servo Drive on the control card are allowing this As this function is a modification of the standard MSD Servo Drive analog inputs also the same pins of connector X4 are used The naming stays the same as well as for the standard inputs as in the firmware a selector has been added to define if the inputs are either current or voltage inputs The maximum common mode voltage with respect to GND for each input shall not be This correct operation depends on the leakage currents of the used analog input bigger than 30 V The maximum voltage between ISAx and ISAx due to normal circuits The analog inputs on the MSD Servo Drive control card are as follows lin operation must not be bigger than 10 V lout lt 50 WA For a correct operation it is recommended to place the analog inputs of Oa o l the MSD Servo Drives at the end of the connection cascade The leakage currents of this input circuit at the MSD Servo Drives are smaller than 50 pA The following principle circuit figure shows how the cascading has to be done for A short circuit protection is currently not implemented in this modification correct operation VA MSD Servo Drive Servo Control Structure Cust
