F06922 Braking resistor phase failure
Message class: Braking Module faulted (14)
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 class: Motor overload (8)
Reaction: OFF2 (NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: KTY:
The motor temperature has exceeded the fault threshold (p0605) or a timer after the alarm threshold was exceeded
(p0604) has expired. The response parameterized in p0610 becomes active. The alarm is withdrawn if the response
threshold for wire breakage or sensor not connected is exceeded (R > 2120 Ohm).
PTC or bimetallic NC contact:
The response threshold of 1650 Ohm was exceeded or the NC contact opened and a timer has expired. The
response parameterized in p0610 becomes active.
Possible causes:
- Motor is overloaded
- motor ambient temperature too high.
- Wire break 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).
See also: p0604, p0605, 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
Message class: Motor overload (8)
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 thermal), p0605 (Mot_temp_mod 1/2 threshold), p0611 (I2t motor model thermal
time constant), 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).
- check the alarm threshold for motor temperature model 1 (I2t) (p0605).
