F07011 Drive: Motor overtemperature
Message value: %1
Message class: Motor overload (8)
Drive object: VECTOR_G
Component: Motor Propagation: GLOBAL
Reaction: OFF2 (NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: KTY84/PT1000 or no sensor:
The measured motor temperature or model temperature has exceeded the fault threshold (p0605) or the timer
(p0606) has elapsed following the alarm threshold (p0604) being exceeded.
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.
- the motor ambient temperature is too high.
- PTC / bimetallic NC contact: Wire breakage or sensor not connected.
Fault value (r0949, interpret decimal):
200:
The motor temperature model 1 (I2t) signals an overtemperature (p0612.0 = 1, p0611 > 0, p0615 reached).
Number of the temperature channel leading to the message (for SME/TM120 (p0601 = 10, 11)).

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 1/3 overtemperature
Message value: %1
Message class: Motor overload (8)
Drive object: VECTOR_G
Component: Motor Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The motor temperature model 1/3 identified that the alarm threshold was exceeded.
Hysteresis:2K.
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.
