9.5 Monitoring and protective functions
Sensor monitoring for wire breakage/short-circuit
If the temperature of the motor temperature monitor is outside the range –50°C to +250°C,
the sensor cable is broken or has short-circuited. Alarm A07915 ("Alarm: temperature sensor
fault") is triggered. Fault F07016 ("Fault: temperature sensor fault") is triggered once the
waiting time defined in p0607 has elapsed.
Fault F07016 can be suppressed by p0607 = 0. If an induction motor is connected, the drive
continues operating with the data calculated in the thermal motor model.
If the system detects that the motor temperature sensor set in p0600 is not connected, alarm
A07820 "Temperature sensor not connected" is triggered.
