Table 80: Selection options for the response to limit value violation
Selection option Description
No Function Limit value monitoring is deactivated.
Warning When a limit value is violated, the amber LED lights up and the associated
message flashes on the display. The information about a current limit value
violation can also be provided via a digital output (
3-7-2-1 or 3-7-3-1 (⇨ Section
7.4 Page 94)
Stop & Trip When a limit value is violated, the speed is reduced along the ramp function
until the unit comes to a stop. The red LED lights up and the associated message
flashes on the display. The restart behaviour depends on the trip reset mode (
3-11-2-1 ). The information about a current limit value violation can also be
provided via a digital output (parameter 3-7-2-1 or 3-7-3-1 (⇨ Section 7.4 Page
94)
