Causes and corrective actions
AL.01 Over voltage
Alarm cause Checking method Corrective action
Main circuit voltage
exceeds the rated
allowable value. Use a voltmeter to check whether
the main circuit input voltage is
within the rated allowable voltage
value. Use the correct voltage
source or connect to the
voltage regulator in series.
Incorrect power input
(incorrect power
system). Use a voltmeter to check if the
voltage system complies with the
specifications. Use the correct voltage
source or connect to the
voltage regulator in series.
Drive hardware failure. Use a voltmeter to check whether
the input voltage of the main
circuit is within the rated allowable
voltage value, and yet the error
still occurs.
Send your servo drive
back to the distributor or
manufacturer.
Built-in regenerative
resistor or
regenerative device is
disconnected. Check whether the PD short-
circuited piece is connected
correctly, or whether the
regenerative resistor or device
wiring is disconnected. Wire the short-circuited
piece correctly or change
the wiring cable.
Burned or damaged of
the internal
regenerative resistor
or regenerative related
device Check whether the regenerative
resistor or regenerative related
device is burnt or damaged. When using the internal
regenerative resistor,
please replace the drive;
When using the
regenerative related
device, please replace it.
The capacity of
internal regenerative
resistor or
regenerative option is
insufficient. Refer to section 6.6.1, check the
capacity of regenerative resistor. Increase the capacity or
add additional
regenerative device.
