Remedy
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 the wiring and connection of the sensor.
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).
Deactivate the temperature sensor fault (p0607 = 0).
Check the adapted parameter values and if required correct.
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.
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 it is not desirable that the controller intervenes:
Increase the ramp-down times.
•
Deactivate the V
•
DC_max
= 0 for U/f control).
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.
•
Adapt the limits to the signal level (p2267, p2268).
•
Check the actual value scaling (p2264).
