Power Module overtemperature Check the following:
- Is the ambient temperature within the de󹪝ned limit values?
- Are the load conditions and duty cycle con󹪝gured accordingly?
- Has the cooling failed?
F06310 Supply voltage (p0210) incorrect‐
ly parameterized
Check the parameterized supply voltage and if required change (p0210).
Check the line voltage.
F07011 Motor overtemperature Reduce the motor load.
Check ambient temperature.
Check the wiring and connection of the sensor.
A07012 I2t motor model overtemperature Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check the 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).
F07086
F07088
Switching over units: Parameter
limit violation
Check the adapted parameter values and if required correct.
F07320 Automatic restart aborted Increase the number of restart attempts (p1211). The current 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 o󹪜 (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 automatic restart (AR) is active. During voltage recovery
and/or when remedying the causes of pending faults, the drive is automatically
switched back on.
F07330 Search current measured too low Increase search current (P1202), check motor connection.
A07400 V
DC_max
controller active If the controller is not to intervene:
• 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 con‐
troller active
The alarm automatically disappears after one of the following measures:
• Increase the current limit (p0640).
• Reduce the load.
• Slow down the ramp up to the setpoint speed.
F07426 Technology controller actual val‐
ue limited
• Adapt the limits to the signal level (p2267, p2268).
• Check the actual value scaling (p2264).
A07444 PID autotuning is activated Automatic setting of the PID controller (autotuning) is active (p2350 > 0). The
alarm disappears automatically after completion of the autotuning.
