Description: Sets the timer between the output of alarm and fault for a temperature sensor fault.
If there is a sensor fault, this timer is started. If the sensor fault is still present after the timer has expired, a corre-
sponding fault message is output.
Note: If the motor is an induction motor, the timer is switched off when setting the minimum value and no alarm is output.
Temperature monitoring is then based on the thermal model.
Description: Sets the system response when the motor temperature reaches the alarm threshold.
Value: 0: No response only alarm no reduction of I_max
1: Alarm with reduction of I_max and fault
2: Alarm and fault no reduction of I_max
Dependency: Refer to: p0601, p0604, p0605
Refer to: F07011, A07910
Note: The I_max reduction is not executed for PTC (p0601 = 1) or bimetallic NC contact (p0601 = 4).
The I_max reduction results in a lower output frequency.
Description: Sets the winding time constant.
The time constant specifies the warm-up time of the cold stator winding when loaded with the motor standstill cur-
rent up until a temperature rise of 63 % of the continuously permissible winding temperature has been reached.
Dependency: This parameter is only used for synchronous motors (p0300 = 2xx).
Refer to: r0034, p0612, p0615
Refer to: F07011, A07012, A07910
Caution: This parameter is automatically preset from the motor database for motors from the motor list (p0301).
When selecting a catalog motor, this parameter cannot be changed (write protection). Information in p0300 should
be carefully observed when removing write protection.
Note: When parameter p0611 is reset to 0, then this switches out the thermal I2t motor model (also refer to p0612).
If no temperature sensor is parameterized, then the ambient temperature for the thermal motor model is referred to
p0625.
