P0604
Motor temperature alarm threshold (factory setting 130 °C)
The alarm threshold is the value at which the inverter is either shut down or I
max
is
reduced (P0610)
P0605
Motor temperature fault threshold (Factory setting: 145 °C)
P0610
Motor overtemperature response
Determines the response when the motor temperature reaches the alarm threshold.
0: No motor response, only an alarm
1: Alarm and reduction of I
max
(factory setting)
reduces the output speed
2: Fault message and shutdown (F07011)
P0640
Current limit (input in A)
