Fault value (r0949, interpret decimal):
200: The motor temperature model 1 (I2t) signals an overtemperature (p0612.0 = 1, p0611 > 0, p0615 reached).
See also: p0604, p0605, p0606, p0612, p0625, p0626, p0627, p0628
Remedy: - Reduce the motor load.
- check the ambient temperature and the motor ventilation.
- check the wiring and the connection of the PTC or bimetallic NC contact.

A07012 (N) Drive: Motor temperature model 1 overtemperature
Reaction: NONE
Acknowledge: NONE
Cause: The thermal I2t motor model for synchronous motors identified that the alarm threshold was exceeded.
See also: r0034 (Motor utilization), p0605 (Mot_temp_mod 1/2 threshold), p0611 (I2t motor model thermal time con-
stant), p0612 (Mot_temp_mod activation)
Remedy: - check the motor load and if required, reduce.
- check the motor ambient temperature.
- check the thermal time constant (p0611).
Note:
p0605 has no influence on the time up to an alarm being issued.

stant), p0612 (Mot_temp_mod activation)
A07014 (N) Drive: Motor temperature model configuration alarm
Reaction: NONE
Acknowledge: NONE
Cause: A fault has occurred in the configuration of the motor temperature model.
Alarm value (r2124, interpret decimal):
1:
All motor temperature models: It is not possible to save the model temperature
See also: p0610 (Motor overtemperature response)
Remedy: - set the response for motor overtemperature to "Alarm and fault, no reduction of I_max" (p0610 = 2).
See also: p0610 (Motor overtemperature response)
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, 50 ms 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)
F07016 Drive: Motor temperature sensor fault
Reaction: OFF1 (NONE, OFF2, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: An error was detected when evaluating the temperature sensor set in p0601.
Possible causes:
- wire breakage or sensor not connected (KTY: R > 2120 Ohm).
- measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm).
Note:
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, 50 ms after alarm A07015.
