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.”
1-11 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.
Overload alarm occurrence time
FHA-C mini AC24V type RSF supermini series
FHA-C mini AC24V type RSF supermini series (RSF-5A)
(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.
(1) The alarm occurs when a current of more than
1.2 times the allowable continuous current of the
actuator flows for about 35 seconds.
(2) The alarm occurs when a current of 3 times the
allowable continuous current of the actuator
flows for about 16 seconds.
(2) The alarm occurs when a current of 2 times the
allowable continuous current of the actuator
flows for about 5 seconds.
It is possible to clear the alarm by inputting ON signal to [CN2 Clear or Alarm clear] if it is not overload,
again.
◆ Deviation counter overflow
The alarm occurs when the value of the deviation counter exceeds the parameter setting value
(PSF-520 No.21 Allowable position deviation). This alarm can be reset by inputting an ON signal to
“CN2 Alarm Clear: ALM-CLR” after inputting an ON signal to “CN2 Clear: CLEAR” or “CN2 Deviation
Clear: DEV-CLR.”
