- DC link voltage oscillations caused by fluctuating loads of the connected drives.
Remedy: - check the feeder cables to the braking resistors.
- If required, increase the value for detecting dissymmetry (p1364).

F06922 Braking resistor phase failure
Message value: %1
Message class: Braking Module faulted (14)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A phase failure for the brake resistor was detected.
Fault value (r0949, interpret decimal):
11: Phase U
12: Phase V
13: Phase W
See also: p3235 (Phase failure signal motor monitoring time)
Remedy: Check the feeder cables to the braking resistors.

F07011 Drive: Motor overtemperature
Message value: %1
Message class: Motor overload (8)
Drive object: VECTOR_G
Reaction: OFF2 (NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: KTY 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.
