Operating ModesServo controlNoteIf a ramp-up/ramp-down time or one direction of rotation limit is activated, parts ofthe motor data identification routine cannot be carried-out. For other parts of themotor data identification routine, the accuracy of the results is diminished becausea ramp-up/ramp-down time is selected. If possible, p1958 should be 0 and nodirection of rotation limit selected (p1959.14 = 1 and p1959.15 = 1).!DangerThe stationary MotID can result in slight movement of up to 210 degrees electrical.For the rotating motor data identification routine, motor motion is initiated, whichcan reach the maximum speed (p1082) and the motor torque corresponding to themaximum current (p0640).The rotating measurement should be carried-out with a motor running at no load(de-coupled from the mechanical system) in order to previous damage/destructionto the load or be influenced by the load. If the motor cannot be de-coupled fromthe mechanical system, then the stress on the mechanical system can be reducedby parameterizing the ramp-up time (p1958) and/or using a speed limit (p1959.14/p1959.15) or using the current and speed limit.If there is a mechanical distance limit, we recommend that the rotatingmeasurement is not carried-out.The EMERGENCY SWITCHING-OFF functions must be completely functionalwhen commissioning the system.All of the relevant safety regulations must be carefully observed in order to excludeany danger for man and machine.© Siemens AG 2006 All Rights ReservedSINAMICS S120 Function Manual, 03/2006 Edition3-99
