Current monitoring for overload
This function extension is available from version 16.00.00!
If the apparent motor current exceeds a defined threshold value
) for a certain time
(
) an overload has taken place.
Monitoring responds as follows:
• The
bCurrentMonitoringOverload
signal is set to TRUE
selection list - digital signals
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.
