Monitoring functions and protective functions
9.5 Thermal motor protection
Sensor monitoring for wire breakage/short-circuit
● A sensor monitoring function for a short-circuit in the sensor cable is possible for a PTC
and a PT1000 or KTY84 sensor. Wire breakage monitoring is possible for a PT1000 or
KTY84 sensor:
If the temperature value lies outside the specified range of -140 °C ... +250 °C, then it is
probable that the sensor cable either has a broken wire or short-circuit. The alarm
A07015 "Drive: Motor temperature sensor alarm" is initiated. After the wait time in p0607
has expired, fault F07016 "Drive: Motor temperature sensor fault" is output.
● If an induction motor is connected, you can suppress fault F07016 by setting p0607 = 0.
The drive then continues to operate with the data calculated in the thermal 3-mass model.
● If the motor temperature sensor set in p0600 is not connected, alarm A07820
"Temperature sensor not connected" is triggered.
