The load torquemonitoring function can then detectwhether the driven load is locked or the force transmission has been interrupted.For the load torque monitoring function, the actual frequency/torque characteristicis compared with the programmed frequency/torque characteristic (refer to P2182 –P2190). If the actual value lies outside the programmed tolerance bandwidth, then,depending on parameter P2181, either warning A0952 or fault F0452 is generated.Parameter P2192 can be used to delay the output of the warning or fault message.This avoids erroneous alarms which could be caused by brief transient states (referto Fig. 3-88).P2186P2185P2188P2187P2190P2189P2183 P2184Torque [Nm]Frequency[Hz]P108201r2198Bit 11 tP2192 P2192A0952ActualtorqueP2182Fig. 3-88 Load torque monitoring (P2181 = 1)DriveshaftDeflectionrollFig. 3-87 Shaft drive with flat belts |
