0x2D4B:001
(P308.01)
Motor overload monitoring (i²*t): Maximum
ulisaon [60 s]
(Mot
or overload: Max.load.for 60s)
30 ... [150] ... 200 %
Maximum permissible thermal motor ulisaon (max. permissible motor
current for 60 seconds).
•
100 % = rated motor current 0x6075 (P323.00)
•
If the motor is actuated with the current set here for 60 seconds, the
maximum permissible thermal motor ulisaon is reached and the
response set in 0x2D4B:003 (P308.03) is executed.
•
If the motor is actuated with a dierent current, the me period unl
the motor overload monitoring funcon is acvated is dierent.
Generally the following applies: the lower the current, the lower the
thermal ulisaon and the later the monitoring funcon is triggered.
0x2D4B:002
(P308.02)
Motor overload monitoring (i²*t): Speed
compensaon
(Motor overload: Speed comp.)
Use this funcon to protect motors that are actuated at a speed below
40 Hz.
•
UL-compliant operaon with motor overload protecon requires the
seng "On [0]"!
0 On Release me for motor overload monitoring is reduced in order to
compensate for the reduced cooling of naturally venlated AC inducon
motors during operaon at low speed.
1 O Funcon deacvated, no reducon of the motor overload monitoring
release me. May require an external motor overload protecon for the
UL-compliant operaon.
0x2D4B:003
(P308.03)
Motor overload monitoring (i²*t): Response
(Motor overload: Response)
Selecon of the response to the triggering of motor overload
monitoring.
•
UL-compliant operaon with motor overload protecon requires the
seng "error [3]"!
•
If monitoring is deacvated by the seng 0x2D4B:003 (P308.03) =
"No response [0]", no motor overload protecon is acve. In this case,
an external motor overload protecon can be provided by the user for
a UL-compliant operaon.

•
R
ead only
Display of the value of the internal i²*t integrator.
•
37500 = 100 % thermal load
•
When power is switched o, this value is saved in the internal
EEPROM.
•
When power is switched on, the saved value is reloaded into the i²*t
integrator.
•
The internal i²*t integrator detects the thermal load based on the load
condions even if the motor overload monitoring is deacvated.
