Parameters
Description
Switching frequency monitoring time t
1
The time t
1
selected must be shorter than the time t
2
or it must be deactivated.
If the switching frequency monitoring time t
1
according to the set mode is not
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
1
.
• Factory setting: 0 s
• Setting range: 0 ... 65 535 s
• In steps of: 1 s
Switching frequency monitoring time t
2
The time t
2
selected must be longer than the time t
1
or it must be deactivated.
The parameter is relevant in relation to the parameter "Maximum number of
starts".
The setting "0 s" deactivates the Switching frequency monitoring time t
2
.
• Factory setting: 0 s
• Setting range: 0 ... 65 535 s
• In steps of: 1 s
Maximum number of starts
This parameter is only relevant in combination with the switching frequency
monitoring time t
2
. If the parameter "Switching frequency monitoring time t
2
"
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
2
according to the set
mode does not have to be observed. An internal counter counts the starts for
which the switching frequency monitoring time t
2
is not observed. At the
latest upon reaching the maximum number of starts, the switching frequency
monitoring time t
2
must be observed once. If the switching frequency moni‐
toring time t
2
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
2
according to the set mode is not observed, the 3RW55 and
3RW55 Failsafe soft starters behave as set in the parameter "Response to ON
command during active monit. time".
• Factory setting: 2
• Setting range: 2 ... 255
• In steps of: 1
