b) P2181 = 2 / 5
Load torque monitoring as anti-stall protection. This means that when a fault
occurs, the actual load torque is above the permissible tolerance bandwidth.
In this case, the load torque characteristic with maximum permissible load
should be determined.

c) P2181 = 3 / 6
Load torque monitoring to detect whether the drive is blocked (stalled) or a
transmission belt has broken. This means that when a fault occurs, the load
torque is either above or below the permissible tolerance bandwidth. In this
case, the load torque characteristic with the minimum and maximum
permissible load should be determined.
