Remedy
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

control, p1280 = 0 for U/f control).
The alarm automatically disappears after one of the follow-
ing 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).
•
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.
Reduce the continuous load.
•
Adapt the load cycle.
•
Check the assignment of rated currents of the motor
•
and power unit.
