Corrective action
• Bttery cable for absolute position
detection system is open.
• Repair the cable or replace the
battery.
2102
(AL.92)
Open battery
cable warning
• Voltage of battery for absolute position
detection system supplied fell to about
3V or less.
(Detected with the encoder.)
• Replace the battery.
• After home position return, droop pulses
remaining are greater than the in-
position range setting.
• Re-try the home position return.
2106
(AL.96)
Home position
setting warning
• Creep speed is high. • Reduce the creep speed.
2116
(AL.9F)
Battery warning
• Voltage of battery for absolute position
detection system installed to servo
amplifier fell to 3.2V or less.
(Detected with the servo amplifier.)
• Replace the battery.
2140
(AL.E0)
Excessive
regenerative
warning
• There is a possibility that regenerative
alarm [2030] may occur.
(Detected 85[%] regenerative level of
the maximum load capacity for the
regenerative register.)
• Refer to the details on the
regenerative alarm [2030].
2141
(AL.E1)
Overload
warning 1
• There is a possibility that overload alarm
[2050], [2051] may occur.
(Detected 85[%] overload level.)
Operation
continues
• Refer to the details on the
overload alarm [2050], [2051].

Servo forced
stop warning
• Servo amplifier are forced stop state.
(Servo amplifier input signal EM1 is
OFF.)
• Ensure safety and deactivate
forced stop.
2147

Controller
forced stop
warning
• A forced stop (EMG) signal is input
from the Motion CPU
Immediate

• Ensure safety and deactivate
forced stop.
• Cooling fan life expiration • Replace the cooling fan of servo
amplifier.
• Replace the servo amplifier.
2148
(AL.E8)
Cooling fan
speed reduction
warning
• The power supply of the cooling fan is
broken.
• Replace the cooling fan of servo
amplifier.
2149
(AL.E9)
Main circuit off
warning
• Servo-on signal was turned on with main
circuit power off.
• Switch on the main circuit power.
2152
(AL.EC)
Overload
warning 2
• During a stop, the status in which a
current flew intensively in any of the U, V
and W phases of the servomotor
occurred repeatedly, exceeding the
warning level.
Any time during
operation
Operation
continues
• Reduce the positioning frequency
at the specific positioning
address.
• Reduce the load.
• Replace the servo amplifier/
servomotor with the one of larger
capacity.
