Parameters
List of Parameters
p0605[0...n] Motor temperature fault threshold / Mot_temp flt thr
Access level: 3
Can be changed: C(3), U, T
Units group: 21_1
Min
0.0 [°C]
Description: Sets the fault threshold for monitoring the motor temperature.
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: The hysteresis for canceling the fault is 2 Kelvin.
When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (refer to p0300).
p0606[0...n] Motor temperature timer / Mot_temp timer
Access level: 4
Can be changed: C(3), U, T
Units group: -
Min
0.000 [s]
Description: Sets the timer for the alarm threshold for the motor temperature monitoring function.
This timer is started when the temperature alarm threshold (p0604) is exceeded.
If the timer expires before the temperature in the meantime falls below the alarm threshold, the fault F07011 is out-
put.
If the temperature fault threshold (p0605) is prematurely exceeded before the timer has expired, then fault F07011
is immediately output.
As long as the motor temperature has still not exceeded the fault threshold and the alarm thresholds have again
been undershot, the fault can be acknowledged.
Dependency: Refer to: p0604, p0605
Refer to: F07011, A07910
Note: With p0606 = 0 s, the timer is de-activated and only the fault threshold is effective.
KTY sensor: When setting the minimum value, the timer is disabled and a fault is not output until p0605 is
exceeded.
PTC sensor, bimetallic NC contact: The timer minimum value has no special significance.
p0607[0...n] Temperature sensor fault timer / Sensor fault time
Access level: 4
Can be changed: C(3), U, T
Units group: -
Min
0.000 [s]
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.
Notice: The parameterized time is internally rounded-off to an integer multiple of 48 ms.
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.
