Extended FunctionsOFF3 torque limits4.19 OFF3 torque limitsDescriptionIf the torque limits are externally specified (e.g. tension controller), then the drivecan only be stopped with a reduced torque. If stopping in the selected time p3490of the infeed has not been completed, the infeed shuts down and the drive coastsdown.In order to avoid this, there is a binector input (p1551), that for a LOW signal, activatesthe torque limits p1520 and p1521. This means that the drive can brake withthe maximum torque by interconnecting the signal OFF 3 (r0899.5) to this binector.Fig. 4-15Torque limits OFF3Function diagram overview (refer to the List Manual) 5620 Torque limits, motoring/regenerating 6620 Upper/lower torque limitOverview of important parameters (refer to the List Manual) p1520 Torque limit, upper/motoring p1521 Torque limit, lower/regenerating© Siemens AG 2006 All Rights ReservedSINAMICS S120 Function Manual, 03/2006 Edition4-229
