2 Operating principle
Timer
It is parameterized in the example as "with closing delay" or "with opening delay".
Runtime and output can be reset with a reset input (R). For the precise output
behavior, please consult the pertinent time diagrams in manual \3\.

Signal conditioning
In the example, signal conditioning is parameterized as follows:
•
"edge rising with memory"
The signal is only reset with "true" at the reset input (R).
•
Negation
Detailed information is available in manual \3\.

Limit monitor
Using limit monitors, the motor current in the example is monitored for its limit value
being exceeded/not met; and the power factor is monitored for when its limit is not
met. When the respective limit value is met, the digital output changes to "true".
When parameterizing the limit value encoder, it is possible to define in which motor
operating mode it will be evaluated. A parameterizable time delay of the monitoring
output has been left at the default setting of 0.5 s for all limit monitors in the
example.
Detailed information is available in manual \3\.
