Monitoring the number of starts

Number of starts monitoring - use
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 also particularly useful for commissioning or manual
control.
The schematic below illustrates the principle of monitoring the number of starts:
Figure 4-39
Permissible starts
The maximum permissible 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:
Active status
Unless deactivated, this function is always active, independent of whether the motor is
running or not (operating state "ON").
