Alarm Status
Segment LED Alarm Code
Display ALM8,4,2,1
Alarm code 0,1 indicates: when Func2/ bit7,6 ="0,0", "0"= output open and "1"= output short.
Operating state when alarm occurred
OPERATING STATE
When control power supply is turned on
When servo ON is inputted
After position command input (when motor is not
rotating)
After position command input (after operating for
a short period)
Corrective Measures
Faulty amplifier control board or
1
power module
2 Faulty servomotor sensor circuit
3 Effective torque is exceeding
rated torque
4 Incorrect combination of amplifier
and motor.
5 Holding brake of servomotor is
not released
6 Incorrect wiring of U, V, W phases
between amplifier and motor
7 One or all of the U, V, W phase
wirings between amplifier and
motor is disconnected
8 Mechanical interference
9 Encoder pulse does not meet motor Set to encoder pulse number of motor
<Overload cause #3: Effective torque is exceeding rated torque>
Repeatedly turning the control power OFF→ON may cause the servomotor to burn.
While investigating this cause, please ensure that sufficient time is allowed for cooling down
after power OFF (30 minutes or more).

CORRECTIVE MEASURES
Replace servo amplifier.
Replace servomotor.
• Monitor torque generated by motor using the estimated effective
torque (Trms) of MODE5/ page12 of remote operator to check if
effective torque is exceeding rated torque.
• Or, calculate effective torque of motor from the load and
operating conditions
→ If effective torque is higher than rated torque, review
operating or load conditions, or replace with larger capacity
motor.
• Check if motor code of Mode4/ page6 of remote controller
conforms to servomotor. Correct if necessary.
Check brake wiring for errors. Replace servomotor if brake wiring
is found to be correct (and voltage is applied as specified),
Check and correct wiring.
Check and correct wiring.
Review operating conditions and limit switch.
