244 Operating Instructions ACU 12/16
Warning thresholds give the user the chance to respond to imminent I²t error shutdown. Via
Warning Limit I2t
615 , you can choose a value between 6% and 100% of thermal load.

Output signals
Digital signals signal that of the function "motor circuit breaker" has been triggered.

1)
Triggering of “motor circuit breaker” function as per
Operation Mode
571 is reported.

2)
1)
For linking to frequency inverter functions
2)
For output via a digital output.
19.6 V-belt monitoring
Continuous monitoring of the load behavior and thus of the connection between the 3-phase
machine and the load is the task of the V-belt monitoring system. Parameter

defines the function behavior if the
Active Current

Trigger Limit Iactive
582 for longer than the parameterized

Operation Mode 581 Function
0 - off The function is deactivated.
1 - Warning
If the active current drops below the threshold value, the warning
"A8000" is displayed.
2 - Fault
The unloaded drive is switched off and error signal "F0402" is
displayed
The error and warning messages can be read out by means of the digital outputs (Signal 22 -
“Warning V-Belt”) or reported to a higher-level control system. The
Trigger Limit Iactive
582 is to
be parameterized as a percentage of the
Rated Current
371 for the application and the possible
operating points.
