Parameter
Description
p0610
Motor overtemperature response
(factory setting: 12)
Determines the behavior as soon as the motor temperature reaches the warning
threshold p0604.
0: Alarm (A07910), no fault.
1: Alarm (A07910); the converter reduces the current limit and starts the timer.
Shutdown with fault (F07011).
2: Alarm (A07910); the converter starts the timer. Shutdown with fault (F07011).
12: As for 2, but the converter considers the last shutdown temperature to calculate
the motor temperature.

Current limit (input in A)
Additional information on the motor temperature monitoring can be found in function diagram
8016 of the List Manual.
8.6.3
Protecting the motor by calculating the motor temperature
The converter calculates the motor temperature based on a thermal motor model. Use the
parameters below to set further variables for the temperature calculation of the motor.

Parameter
Description
p0601
Motor temperature sensor type
(factory setting: 0)
0: No sensor
p0604
Mot_temp_mod 2/KTY Warning threshold
(factory setting: 130 °C)
Threshold for monitoring the motor temperature
.
.
After exceeding the threshold, the converter reports fault F07011.
p0605
Mot_temp_mod 1/2 Threshold
(factory setting: 145 °C)
Timer for monitoring the motor temperature in motortemperature model 2
.
.
The converter starts the timer when the temperature warning threshold is exceeded
(p0604).
p0610
Motor overtemperature response
(factory setting: 12)
Determines the behavior as soon as the motor temperature reaches the warning
threshold p0604.
0: Warning (A07910), no fault.
1: Warning (A07910); current limit will be reduced and timer started. Shutdown
with fault (F07011).
2: Warning (A07910); timer is started. Shutdown with fault (F07011).
12: As for 2 but the last shutdown temperature is used to calculate the motor
temperature (factory setting).
p0611
I2t motor model thermal time constant
(factory setting: 0 s)
The parameter is only effective for synchronous motors.
On selecting a motor from the motor list (p0301), the converter sets up the parameter
value automatically.
