Remedy
Check the connection to the signal source for interrupts.
Check the level of the signal supplied.
The input current measured by the analog input can be read out in r0752.
Check that the sensor is connected correctly.
Check the following:
- Is the ambient temperature within the defined limit values?
- Are the load conditions and duty cycle configured accordingly?
- Has the cooling failed?
Check the parameterized supply voltage and if required change (p0210).
Check the line voltage.
Reduce the motor load.
Check ambient temperature.
Check sensor's wiring and connection.
Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check thermal time constant p0611.
Check overtemperature fault threshold p0605.
Check that the sensor is connected correctly.
Check the parameter assignment (p0601).
Make sure that the sensor is connected correctly.
Check the parameterization (p0601).
Check the adapted parameter values and if required correct.
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.
Create 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.
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.
Increase search current (P1202), check motor connection.
If the controller is not to intervene:
Increase the ramp-down times.

Deactivate the V

DC_max
for V/f control).
The alarm automatically disappears after one of the following measures:
Increase the current limit (p0640).

Reduce load.

Increase the ramp-up time to the speed setpoint.
