15.2 Servo driver
If an alarm occurs, error signal output contact (Alarm) is turned OFF, and the motor stops by
the action of dynamic brake.
Actions to be taken in case of an alarm
Screen display Cause Corrective action
Normal
AL-00
EMER STOP
External ESTOP contact input
turned OFF.
Check external DC 24V power
supply.
Check if the ESTOP contact is
turned ON.
AL-01
OVER CURNT
Servo driver output terminal (U,
V, W) short-circuited, output
overcurrent.
Check the output terminal wiring.
Restart after resetting alarm.
Replace driver if O.C. continues.
AL-02
OVER VOLT
Input voltage excessive (greater
than 280V).
Regeneration control resistance
burned.
Load GD
2
excessive.
Use input voltage lower than 230V.
Replace control resistance, increase
acceleration/deceleration time.
Replace servo driver.
AL-03
OVER LOAD
Mechanical overload.
Motor miswiring.
Check load condition.
Check the motor and encoder wiring.
AL-04
POWER FAIL
Main power shut off during Servo
ON status.
Check the 3-phase main power
supply (R, S, T) input status.
AL-05
LINE FAIL
Motor and encoder set value
error, motor and encoder
miswiring, defective encoder,
mechanical overload.
Check motor and encoder wiring and
set values.
Remove excessive load.
AL-06
OVER HEAT
Ambient temperature increased.
Continuous overload operation.
Improve heat-shield system condition
(ambient temperature to be less than
50
℃
). Check load condition.
AL-07
OVER SPEED
Excessive gain, parameter set
value error, excessive gravity
load.
Adjust gain.
Check parameters (P3-14).
Remove excessive gravity load.
AL-08
FOLLOW ERR
Rapid acceleration/deceleration,
gain set value error, command
pulse frequency excessive
(higher than 300 kpps),
miswiring, mechanical overload.
Adjust position gain, increase menu
(P4-03) set value, adjust command
pulse frequency, check motor and
encoder wiring.
