Alarm details
AL.25 Absolute
position erase
Absolute position
data is erased.
1. Voltage drop in encoder.
(Battery disconnected.)
Change the battery and
make home position setting
again.
2. Battery voltage fell to about 2.8V or
less.
Change the battery.
Always make home position
setting again.
3. Battery cable or battery is faulty.
4. Encoder cable fault.
Repair or change the
encoder cable.
5. Encoder fault.
Change the servo motor.
Power was
switched on for the
first time in the
absolute position
detection system.
6. Home position not set.
Change the battery and
make home position setting
again.
AL.30 Regenerative
error
Permissible
regenerative power
of the built-in
regenerative
resistor or
regenerative option
is exceeded.
1. Incorrect setting of parameter No.
PA02
Set correctly.
1
2. High-duty operation or continuous
regenerative operation caused the
permissible regenerative power of the
regenerative option to be exceeded.
<Checking method>
Call the status display software (MR
Configurator2
TM
), and check the
regenerative load ratio.
1. Reduce the frequency of
positioning.
2. Use the regenerative
option of larger capacity.
3. Reduce the load.
3. Bus voltage is abnormal.

: 400VDC or more
Check the power supply.
4. Built-in regenerative resistor or
regenerative option is not connected.
Connect correctly.

5. Built-in regenerative resistor or
regenerative option faulty.
Change the driver or
regenerative option.
Regenerative
transistor fault
6. Driver fault.
(Regenerative transistor fault.)
<Checking method>
1. The regenerative option has
overheat abnormally.
2. The alarm occurs even after removal
of the built-in regenerative resistor or
regenerative option.
Change the driver
7. Driver fault.
(Regenerative circuit fault.)
Change the driver.
