The following example illustrates how the LED blinks in case of an alarm.
0.5s 0.5s 0.5s 2s 0.5s 0.5 s 0.5s
In the above example, the LED blinks 4 times at 0.5-s intervals, which indicates an “encoder reception
error.”

Protective functions
HA-680 drivers provide the following protective functions and show the alarm displays on 1-10.
◆
Overload
The driver always monitors the motor current, and if the current exceeds the curve in the figure below,
the overload alarm occurs. Occurrence of the overload alarm varies depending on the actuator.
FHA-C mini AC24V type
(1)
The alarm occurs when a current of more than
1.25 times the allowable continuous current of
the actuator flows for about 170 seconds.
(2)
The alarm occurs when a current of 3 times the
allowable continuous current of the actuator
flows for about 16 seconds.
RSF supermini series (RSF-5B)
(1)
The alarm occurs when a current of more than
1.2 times the allowable continuous current of
the actuator flows for about 35(45) seconds.
(2)
The alarm occurs when a current of 2 times the
allowable continuous current of the actuator
flows for about 5(6) seconds.
