Overview of Alarms
Remedy: - check the line supply voltage setting (p0210).
- check the line supply for an overvoltage condition.
- reduce the modulation depth reserve (p3480).
- reduce the reactive current setpoint.

207011 <location>Drive: Motor overtemperature
Reaction: OFF2 (NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: KTY:
The motor temperature has exceeded the fault threshold (p0605) or the timer stage
(p0606) after the alarm threshold was exceeded (p0604) has expired.
VECTOR: The response parameterized in p0610 becomes active.
PTC:
The response threshold of 1650 Ohm was exceeded and the timer stage (p0606) has
expired.
VECTOR: The response parameterized in p0610 becomes active.
Possible causes:
- motor is overloaded.
- motor ambient temperature too high.

Remedy: - reduce the motor load.
- check the ambient temperature.

207015 <location>Drive: Motor temperature sensor fault, alarm
Reaction: NONE
Acknowledge: NONE
Cause: An error was detected when evaluating the temperature sensor set in p0600 and p0601.
With the fault, the time in p0607 is started. If the fault is still present after this time has
expired, then fault F07016 is output; however, at the earliest, 1 s after alarm A07015.
Possible causes:
- wire breakage or sensor not connected (KTY: R > 1630 Ohm).
- measured resistance too low (PTC: R < 30 Ohm, KTY: R < 340 Ohm).
Note:
For induction motors, the model value is selected for the temperature monitoring.
For synchronous motors, the temperature monitoring is disabled and the ambient
temperature is displayed in r0035.
Remedy: - check that the sensor is connected correctly.
- check the parameterization (p0600, p0601).

207016 <location>Drive: Motor temperature sensor fault, fault
Reaction: OFF1 (NONE, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: An error was detected when evaluating the temperature sensor set in p0600 and p0601.
Possible causes:
- wire breakage or sensor not connected (KTY: R > 1630 Ohm).
- measured resistance too low (PTC: R < 30 Ohm, KTY: R < 340 Ohm).
Note:
For induction motors, the model value is selected for the temperature monitoring.
For synchronous motors, the temperature monitoring is disabled and the ambient
temperature is displayed in r0035.
If alarm A07015 is present, the time in p0607 is started. If the fault is still present after this
time has expired, then fault F07016 is output; however, at the earliest, 1 s after alarm
A07015.
