F07011 Drive: Motor overtemperature
Reaction: OFF2 (NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: KTY:
The motor temperature has exceeded the fault threshold (p0605) or the timer (p0606) after the alarm threshold was
exceeded (p0604) has expired. The response parameterized in p0610 becomes active.
PTC or bimetallic NC contact:
The response threshold of 1650 Ohm was exceeded or the NC contact opened and the timer (p0606) has expired.
The response parameterized in p0610 becomes active.
Possible causes:
- motor is overloaded.
- motor ambient temperature too high.
- wire breakage or sensor not connected.
Fault value (r0949, interpret decimal):
When the I2t motor model is activated (p0612 bit 0 = yes, p0611 > 0), fault value= 200 refers to the fact that the fault
has been triggered by the I2t motor model.
See also: p0604 (Motor temperature alarm threshold), p0605 (Motor temperature fault threshold), p0606 (Motor tem-
perature timer), p0610 (Motor overtemperature response)
Remedy: - reduce the motor load.
- check the ambient temperature.
- check the wiring and sensor connector.

perature timer)
A07012 (N) Drive: I2t motor model overtemperature
Reaction: NONE
Acknowledge: NONE
Cause: The thermal I2t motor model (for synchronous motors) identified that the temperature alarm threshold was exceeded.
See also: r0034 (Motor utilization), p0605 (Motor temperature fault threshold), p0611 (I2t motor model thermal time
constant)
Remedy: - check the motor load and if required, reduce.
- check the motor ambient temperature.
- check the thermal time constant p0611.
- check the overtemperature fault threshold p0605 (= alarm threshold for the I2t motor model, see p0612)
A07015 Drive: Motor temperature sensor alarm
Reaction: NONE
Acknowledge: NONE
Cause: An error was detected when evaluating the temperature sensor set in 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, 0.2 s after alarm A07015.
Possible causes:
- wire breakage or sensor not connected (KTY: R > 2120 Ohm).
- measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm).
Remedy: - make sure that the sensor is connected correctly.
- check the parameterization (p0601).

timer)
