Parameters to set the motor temperature monitoring with sensor
Table 7- 28 Parameters for detecting the motor temperature via a temperature sensor
Parameter Description
P0335 Specify the motor cooling
0: Self-ventilated - with fan on the motor shaft (IC410* or IC411*) - (factory setting)
1: Forced ventilation - with a separately driven fan (IC416*)
2: Self-ventilated and inner cooling* (open-circuit air cooled)
3: Forced ventilated and inner cooling* (open-circuit air cooled)
Terminal no.
14 PTC+
KTY anode
ThermoClick
P0601 Motor temperature sensor type
0: No sensor (factory setting)
1: PTC thermistor (→ P0604)

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)
