If this condition is not met, the limit values must be reduced. If 30 of the bending limit moment and lateral limit force occur at the same time, only 40 of the longitudinal limit force is permissible and the nominal (rated) torque must not be exceeded. The permissible bending moments, longitudinal forces and lateral forces can affect the measurement result by approx. 1 of the nominal (rated) torque. If the nominal torque is exceeded, the maximum control range of the signal output electronics must be observed. Greater signal deviations occur for customer-specific torques Mdk<Mnom than for Mnom/Mdk 2 Operation at the maximum permitted nominal speed can affect the measurement result as 0.1 of the nominal torque. The effect decreases quadratically as speed decreases. For example, if measurements are performed at 30 of the nominal speed, the effect is reduced to <0.01. Greater signal deviations occur for customer-specific torques Mdk<Mnom than for Mnom/Mdk CS-T-04-MDEX (07.04.2010) 6
