List Manual (LH14), 01/2016, A5E33842313
Alarm value (r2124, interpret decimal):
200:
Motor temperature model 1 (I2t): Temperature too high (p0605).
300:
Motor temperature model 3: Temperature too high (p5398).
See also: r0034 (Motor utilization thermal), p0605 (Mot_temp_mod 1/2/sensor threshold and temperature value),
p0611 (I2t motor model thermal time constant), p0612 (Mot_temp_mod activation), p0613 (Mot_temp_mod 1/3
ambient temperature)
Remedy:
- check the motor load and if required, reduce.
- check the motor ambient temperature.
- check activation of the motor temperature model (p0612).
Motor temperature model 1 (I2t):
- check the thermal time constant (p0611).
- check the alarm threshold (p0605).
Motor temperature model 3:
- check the motor type.
- check the alarm threshold (p5398).
- check the model parameters.

A07014 (N)
Drive: Motor temperature model configuration alarm
Message class:
Motor overload (8)
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).

A07015
Drive: Motor temperature sensor alarm
Message class:
External measured value / signal state outside the permissible range (16)
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, PT1000: R > 2120 Ohm).
- measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm, PT1000: R < 603 Ohm).
Remedy:
- make sure that the sensor is connected correctly.
- check the parameterization (p0601).
