Switching frequency monitoring time t
Switching frequency monitoring time t

Description
The time t
selected must be shorter than the time t

If the switching frequency monitoring time t
observed, the 3RW55 and 3RW55 Failsafe soft starters behave as set in the
parameter "Response to ON command during active monit. time".
The setting "0 s" deactivates the Switching frequency monitoring time t

The parameter is relevant in relation to the parameter "Maximum number of
starts".
The setting "0 s" deactivates the Switching frequency monitoring time t

This parameter is only relevant in combination with the switching frequency
monitoring time t
is deactivated (0 s, factory setting), the parameter "Maximum number of
starts" is also deactivated.
The parameter "Maximum number of starts" determines the number of starts
for which the switching frequency monitoring time t
mode does not have to be observed. An internal counter counts the starts for
which the switching frequency monitoring time t
latest upon reaching the maximum number of starts, the switching frequency
monitoring time t
toring time t
is observed before reaching the maximum number of starts, the

counter begins again at "1".
If, upon reaching the maximum number of starts, the switching frequency
monitoring time t
3RW55 Failsafe soft starters behave as set in the parameter "Response to ON
command during active monit. time".
