Remedies for warnings
If AL.E6 occurs, the servo off status is established. If any other warning occurs, operation can be continued but an alarm may take
place or proper operation may not be performed. Use the optional servo configuration software to refer to the cause of warning.
Display Name Definition Cause Action
In incremental system:
1. Positioning operation
was performed without
home position return.
2. Home position return
ended abnormally. 1. Positioning operation was performed
without home position return.
2. Home position return speed could
not be decreased to creep speed.
3. Limit switch was actuated during
home position return starting at other
than position beyond dog. 1. Perform home position
return.
2. Review home position
return speed/creep
speed/moving distance after
proximity dog. AL.90 Home position
return
incomplete
In absolute position
detection system:
1. Positioning operation
was performed without
home position setting.
2. Home position setting
ended abnormally. 1. Positioning operation was performed
without home position setting.
2. Home position setting speed could
not be decreased to creep speed.
3. Limit switch was actuated during
home position setting starting at other
than position beyond dog. 1. Perform home position
setting.
2. Review home position
setting speed/creep
speed/moving distance after
proximity dog.
1. Battery cable is open. Repair cable or changed. AL.92 Open battery
cable warning
Absolute position
detection system battery
voltage is low.
2. Battery voltage dropped to 2.8V or
less. Change battery.
1. Droop pulses remaining are greater
than the in-position range setting. Remove the cause of droop
pulse occurrence
2. Command pulse entered after
clearing of droop pulses. Do not enter command
pulse after clearing of droop
pulses.
AL.96 Home position
setting warning
Home position setting
could not be made.
3. Creep speed high. Reduce creep speed.
1. Software limit was set within actual
operation range. Set parameter No. 48 to 51
correctly.
2. Point table of position data in excess
of software limit was executed. Set point table correctly.
AL.98 Software limit
warning
Software limit set in
parameter is reached.
3. Software limit was reached during
JOG operation or manual pulse
generator operation. Perform operation within
software limit range.
AL.9F Battery warning Voltage of battery for
absolute position
detection system
reduced. Battery voltage fell to 3.2V or less. Change the battery.
AL.E0 Excessive
regenerative
warning
There is a possibility
that regenerative power
may exceed permissible
regenerative power of
built-in regenerative
brake resistor or
regenerative brake
option. Regenerative power increased to 85%
or more of permissible regenerative
power of built-in regenerative brake
resistor or regenerative brake option.
Checking method
Call the status display and check
regenerative load ratio. 1. Reduce frequency of
positioning.
2. Change regenerative
brake option for the one with
larger capacity.
3. Reduce load.
AL.E1 Overload
warning
There is a possibility
that overload alarm 1 or
2 may occur. Load increased to 85% or more of
overload alarm 1 or 2 occurrence level.
Cause, checking method
Refer to AL.50, 51. Refer to AL.50, AL.51.
1. Noise entered the encoder. Take noise suppression
measures. AL.E3 Absolute
position counter
warning
Absolute position
encoder pulses faulty.
2. Encoder faulty. Change servo motor.
AL.E6 Servo
emergency stop
warning
EMG-SG is open. External emergency stop was made
valid. (EMG-SG opened.) Ensure safety and
deactivate emergency stop.
AL.E9 Main circuit off
warning Servo was switched on
with main circuit power
off. Switch on main circuit
power.
