Response to overload
In the case of overload, the SIMOCODE pro response can be additionally
adjusted here.
Further information: See "Tables of responses of SIMOCODE pro" in Chapter
"Important information" and the "Responses" table in Chapter 3.1
"Introduction".
Notice
With motors for EEx e applications, the response must remain set to
"Tripping!"
Cooling down period
The cooling down period is the amount of time that must elapse before an
overload trip can be reset. This is usually five minutes. The thermal memory
(motor model – see below) is deleted after the cooling down period elapses.
SIMOCODE pro supply voltage failures during this time extend the specified
time accordingly.
Range:
Thermal motor model (thermal memory)
When the motor rated current (I
s
) is at 100%, the "Thermal motor model" is
87% (1/1,15 x 100%) in a steady state and 100% at the moment of an
overload trip.
Pause time
The pause time is the specified time for the cooling response of the motor
when tripped under normal operating conditions (not in the case of an
overload trip). After this interval, the thermal memory in SIMOCODE pro is
deleted and a new cold start is possible. This makes frequent start-ups
possible within a short period of time.
Cooling down
period:
60 to 6553.5 seconds
Default: 300 s
