Load failure monitoring

Using this function, the inverter monitors the load using an external signal. It can be fed in
from an encoder or a digital input, for example.
The inverter evaluates whether a load signal is available. If the load signal fails for a time
longer than that set in p2192, then the inverter outputs fault F07936.
Examples of how the function can be used:
● Drive belt monitoring for fans and conveyor belts
● Blocking protection for pumps and conveyor belts
Connect the load signal using p3223, for example p3232 = 722.4. In the factory setting, the
load failure monitoring function is not active.
Set the delay time for the fault message in p2192.
