Alarm code
Alarm name Causes/countermeasures
047
P, A, D
Driver limited
Deviation exceeded
warning
Cause: Present operating conditions or high actuator sliding
resistance may be causing excess deviation.
Countermeasure: Lower the acceleration/deceleration setting.
Perform maintenance such as greasing, etc.
048 Driver overload warning
Cause: The load current value exceeds the setting of Parameter No.
143 “Overload Load Level Ratio”.
This alarm retains alarm status until it is reset.
This alarm turns ON when the load current value exceeds the setting.
Countermeasure: Lower the acceleration/deceleration setting. Or
increase the pause ratio.
04A
Estimated life exceeded
warning
Cause: Driver unit motor power capacitor power capacitance has
decreased by 20 %.
Countermeasure: Replace the driver unit as soon as possible.
04C Low fan rotation speed
Cause: The number of revolution of the fan in the fan unit mounted on
the driver unit has dropped by 30 %.
Countermeasure: Replace the fan unit as soon as possible.
Refer to [12.3.2 How to Replace Fan Unit or 12.3.3
How to Replace Fan Unit for 200V Driver Unit] for
how to make replacement.
04D
Fan total running time
exceeded
Cause: Fan total running time has exceeded the replacement
guidelines.
Countermeasure: The alarm can be canceled without replacing the fan
unit, but we recommend replacing the fan unit
before it breaks down as an aspect of preventive
maintenance.
Refer to [12.3.2 How to Replace Fan Unit or 12.3.3
How to Replace Fan Unit for 200V Driver Unit] for
how to make replacement.
04E
Travel count target value
exceeded
Cause: The total travel count set by Parameter No.147
“
Total Travel
Count Target Value” has been exceeded.
04F
Travel distance target
value exceeded
Cause: The total travel distance set by Parameter No.148
“
Total
Travel Distance Target Value” has been exceeded.
068
S
Driver limited
SRAM access error
Cause: Servo monitor is not operated in the normal condition because
of noise or malfunction of consisting parts.
Countermeasure: 1) Take proper measures against noise.
2) When the servo monitoring function is not used,
set parameter No.112 “Monitoring mode” to “0”.
3) If the operation is not improved in use of the
servo monitoring function in spite of measures
against noise, Please contact IAI.
