5.14.10 Current monitoring for overload
This function extension is available from version 16.00.00!
If the apparent motor current exceeds a defined threshold value C00124/1
) for a certain time
(C00563/1
) an overload has taken place.
Monitoring responds as follows:
•The bCurrentMonitoringOverload signal is set to TRUE
see selection list - digital signals
• The response set in C00584/1 is activated (Lenze setting: "No response")
•The OC18 error message, current monitoring overload, is entered into the logbook.
•The bCurrentMonitoringOverload status output of the LS_DeviceMonitor FB is set to TRUE.
If the overload decreases, the apparent motor current has to decrease below the value
C00124/1 - 0.05 x I
rated
in order that the bCurrentMonitoringOverload signal can accept the FALSE
state.
When bCurrentMonitoringOverload = FALSE, the delay time in the resolution is set to the value 0 s
again.
