299
F07011 Motor overtemperature Reduce the motor load.
Check ambient temperature.
Check the wiring and connection of the sensor.
A07012 I2t Motor Module overtemperature Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check thermal time constant p0611.
Check overtemperature fault threshold p0605.
A07015 Motor temperature sensor alarm Check that the sensor is connected correctly.
Check the parameter assignment (p0601).
F07016 Motor temperature sensor fault Make sure that the sensor is connected correctly.
Check the parameterization (p0601).
Deactivate the temperature sensor fault (p0607 = 0).
F07086
Unit switchover: Parameter limit
Check the adapted parameter values and if required correct.
F07320 Automatic restart aborted Increase the number of restart attempts (p1211). The actual number of
start attempts is shown in r1214.
Increase the wait time in p1212 and/or monitoring time in p1213.
Connect an ON command (p0840).
Increase the monitoring time of the power unit or switch off (p0857).
Reduce the wait time for resetting the fault counter p1213[1] so that fewer
faults are registered in the time interval.
A07321 Automatic restart active Explanation: The automa
tic restart (AR) is active. During voltage recovery
and/or when remedying the causes of pending faults, the drive is auto-
matically switched back on.
Search current measured too low
Increase search current (p1202), check motor connection.
A07400 V
DC_max
controller active If it is not desirable that the controller intervenes:
• Increase the ramp-down times.
• Deactivate the V
DC_max
controller (p1240 = 0 for vector control, p1280
= 0 for U/f control).
A07409 U/f control, current limiting control-
ler active
The alarm automatically disappears after one of the following measures:
• Increase the current limit (p0640).
• Reduce the load.
• Slow down the up ramp for the setpoint speed.
F07426 Technology controller actual value
limited
• Adapt the limits to the signal level (p2267, p2268).
• Check the actual value scaling (p2264).
F07801 Motor overcurrent Check current limits (p0640).
Vector control: Check current controller (p1715, p1717).
U/f control: Check the current limiting controller (p1340 … p1346).
Increase acceleration ramp (p1120) or reduce load.
Check motor and motor cables for short circuit and ground fault.
Check motor for star-delta connection and rating plate parameterization.
Check power unit / motor combination.
Select flying restart function (p1200) if switched to rotating motor.
