Operating Instructions COMPAX-M / -SMachine zero mode808.2.7 Machine zero modeP212: setting the machine zero mode="0": MZ equals external initiator rounded with resolver zero & machine zero travelusing 2 reversing initiators.="1": MZ equals external initiator rounded with resolver zero.="3": MZ equals external zero pulse*="4": MZ equals external initiator rounded with the external zero pulse. *="5": MZ equals resolver zero="6": reserved="7": MZ equals external initiator (without resolver zero).="8": MZ equals a limit switch="10": MZ teach="11": Machine zero - initiator (without resolver zero) with 2 reversing initiatorsP212 becomes valid immediately after a modification.* P212=3 & P212=4 is only permitted for COMPAX XX00 and COMPAX XX30.Function of the machine zero modeP212 ="0"Start search direction / initiator side ApplicationP213: defines the initiator flank of the machine zeroinitiator that is being evaluated; i.e. the sidefrom which the initiator is approached.P3: the prefix defines the start search direction.P215: influences the start search direction duringfind machine zero.P29: shifts the actual machine zero in the directionof the clockwise rotating motor.P216: sets the limit switch position(must also then be set if there are noconfigured limit switches (P217=0)Linear movementsP215="0": the motor rotates clockwise when traveling in the positive direction; i.e.the positive end in the diagram is on the right-hand side.P212="0": operating mode with reversing initiators; i.e. with 3 initiators.P217="0": operating mode without end initiators. I1 and I2 act as reversinginitiators during "Find machine zero".P216="0": the I1 initiator is started by the clockwise rotating motor.P3 = positive (when P3 = negative, reverses start search direction)E2 MN E1gear doesn`t changethe directiondirection "clockwise rotating motor"Overview:Machine zeroequals externalinitiator &resolver zero / 2reversinginitiators.Example of areference systemdefinition
