Cause:
The voltage measurement does not supply any plausible values and is not used.
Alarm value (r2124, interpret bitwise binary):
Bit 1: Phase U
Bit 2: Phase V
Bit 3: Phase W
Remedy:
The following parameterization must be made in order to deactivate the alarm:
- Deactivate voltage measurement (p0247.0 = 0).
- Deactivate flying restart with voltage measurement (p0247.5 = 0) and deactivate fast flying restart (p1780.11 = 0).
F06310 (A)
Supply voltage (p0210) incorrectly parameterized
Reaction:
NONE (OFF1, OFF2)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The measured DC voltage lies outside the tolerance range after precharging has been completed.
Permissible range:
1.16 * p0210 < r0070 < 1.6 * p0210
Note:
The fault can only be acknowledged when the drive is switched off.
See also: p0210 (Drive unit line supply voltage)
Remedy:
- check the parameterized supply voltage and if required change (p0210).
- check the line supply voltage.

A06921 (N)
Braking resistor phase asymmetry
Reaction:
NONE
Acknowledge:
NONE
Cause:
- the three resistors of the braking chopper are not symmetrical.
- 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 asymmetry (p1364).

F06922
Braking resistor phase failure
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
Reaction:
OFF2 (NONE, OFF1, OFF3, STOP2)
Acknowledge:
