Monitoring the number of starts

Monitoring the number of starts can protect system parts (motors and
switching devices such as soft starters and converters) from too many start
processes within a parameterizable time frame and, thus, prevent damage.
This is particularly useful for commissioning or manual control.
The following schematic illustrates the principle of monitoring the number of
starts.
Time frame
Fig. 5-9: Monitoring the number of starts
Permissible starts
The maximum number of starts is set here. The time interval "Time range
for starts" commences to run after the first start. After the second to last
permissible start has been executed, the "Just one start possible" pre-
warning is generated.
Permissible starts:
Time range for starts
The time range for permissible start processes is set here. The maximum
number of starts is only available again after the parameterized time range
for starts has elapsed. The number of available starts is shown by the analog
value "Permissible starts - Actual value".
Time range for starts:
Activity
Unless deactivated, this function is always active, independent of whether
the motor is running or not (operating state "ON").
Response at overshoot
Here you can set the response for when the number of starts within the
time range for starts has been overshot:
