What it means
A07014 tells you that the configuration of the motor temperature model is faulty — the alarm points at the model's setup, not at a measured motor temperature. The drive writes a numeric alarm value into r2124, which you read as a decimal number to identify the exact configuration problem. Depending on how the drive is configured, the same condition can also be output as a message without any reaction (N).
Why it appears
- The configuration of the motor temperature model contains a fault.
- Alarm value 1: in all motor temperature models, it is not possible to save the model temperature.
- On S120/S150 for SERVO, alarm value 300 is added: for motor temperature model 3, the threshold value for alarm (r5398) is set higher than the threshold value for fault (r5399).
What to check
- Read the alarm value in r2124 as a decimal number to see which configuration problem the drive found.
- Set the response for motor overtemperature to "Alarm and fault, no reduction of I_max" — p0610 = 2.
- On S120/S150 with SERVO and alarm value 300: check the threshold values r5398 and r5399 and correct them so that the alarm threshold (r5398) is no longer higher than the fault threshold (r5399).
Reading the message value
- The drive places the alarm value in r2124; interpret it as a decimal number.
- 1 — all motor temperature models: it is not possible to save the model temperature.
- 300 — motor temperature model 3: the threshold value for alarm (r5398) is higher than the threshold value for fault (r5399); the manual lists this value for SERVO on S120/S150.
Parameters the manual names
- r2124 — alarm value; read it here as a decimal number to get the value 1 or 300 behind A07014.
- p0610 — motor overtemperature response; the remedy for this alarm is to set it to 2, "Alarm and fault, no reduction of I_max".
- r5398 — displays the alarm threshold of motor temperature model 1/3 (image of p5390); check it when alarm value 300 is shown.
- r5399 — displays the fault threshold of motor temperature model 1/3 (image of p5391); it must not sit below r5398.
- p5390 — alarm threshold of motor temperature model 1/3, the parameter whose value r5398 mirrors.
- p5391 — fault threshold of motor temperature model 1/3, the parameter whose value r5399 mirrors.
Acknowledging and restarting
No acknowledgement is demanded and the drive takes no protective reaction while this alarm is active, so there is no reset step at the panel. The alarm goes away once the configuration fault is removed: set p0610 to 2 and, if alarm value 300 was shown, bring the thresholds r5398 and r5399 back into the correct order.
What differs between the drive families
Straight from the manuals' own fields — A07014 is not described identically everywhere.

Questions technicians ask
What does alarm A07014 mean in a SINAMICS drive?
It reports a fault in the configuration of the motor temperature model, not a measured overtemperature. The alarm value in r2124 (read as a decimal number) identifies the problem: 1 means the model temperature cannot be saved, 300 means the alarm threshold r5398 lies above the fault threshold r5399.
How do I fix alarm A07014?
Set the motor overtemperature response p0610 to 2 ("Alarm and fault, no reduction of I_max"). If the alarm value is 300, also check and correct the threshold values r5398 and r5399. The alarm requires no acknowledgement.
Why does A07014 appear although the motor is not overheated?
Because it is a configuration alarm of the temperature model: either the model temperature cannot be saved at all, or the thresholds are ordered incorrectly (r5398 above r5399).
