AL.2F Regenerative energy error
Alarm cause Checking method Corrective action
When the regenerative
load rate exceeds 100%.
1.
Check if the
acceleration/deceleration
time is too short.
2.
Check if the frequency of
forward and reverse
rotation is too fast.
1.
Adjust the
acceleration
/deceleration time, or
reduce the frequency
of forward and reverse
rotation.
2.
Press SET button in
current alarm screen
display.
3.
Restart the power.
AL.30 Pulse output frequency excess
Alarm cause Checking method Corrective action
Detector output error which is
caused by encoder error. Check the error history to
see whether it is
accompanied with an
encoder error (AL0B,
AL0C, AL22, AL26, AL27). Follow the
corrective action of
AL.0B, AL.22,
AL.26, AL.27.
The output pulse exceeds the
hardware allowable range. Check whether the
following conditions exist:
(a) Motor feedback
speed> PA41.
(b) (Motor speed/60) *
detector output pulse
number per revolution >
20x10
6
Correctly set PA41
and PA14: PA41>
motor speed and
(motor speed/60)*
the detector output
pulse number per
revolution <20x10

Alarm cause Checking method Corrective action
The drive current feedback is
abnormal. Restart the drive. If the issue persists, send your
servo drive back to the distributor or manufacturer.
