4 Faults and alarms
4.2 List of faults and alarms
F06310 (A) Supply voltage (p0210) incorrectly parameterized
Message class: Network fault (2)
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.
See also: p0210 (Drive unit line supply voltage)
A06921 (N) Braking resistor phase asymmetry
Message class: Braking Module faulted (14)
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
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: KTY84/PT1000:
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 The alarm is withdrawn if the response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 breakage or sensor not connected.
Fault value (r0949, interpret decimal):
200:
Motor temperature model 1 (I2t): temperature too high.
