Load missing delay 0 ... 10000 [ms] P2180 (2000)
Note:
-It may be that the motor is not connected (load missing) or a phase could be missing.
-If a motor setpoint cannot be entered and the current limit (P2179) is not exceeded, Alarm A0922 (no load applied) is issued when delay time (P2180) expires.

Parameter P2181 activates or
Using the load torque monitoring, it is possible to detect a mechanical failure or an overload condition of the mechanical transmission line, e.g. a broken drive belt or a stalled conveyor belt. In this case, the actual torque/frequency actual value is compared to a programmed envelope characteristic (refer to P2182 - P2190). If the actual torque/frequency actual value lies above or below the envelope curve, then after the delay time P2192 expires, as a function of P2181, alarm A0952 is output or the drive inverter is tripped with fault message F0452.
