A
Manual mode
Servo is OFF
Press setting
button
(RESET input
is ON)
<Condition>
In registering the intermediate position by Direct teaching, the alarm occurs
when the position is registered before the return to origin is completed.
<Countermeasure>
Perform the return to origin.
B
Any condition
RESET input
is ON
(Press setting
button)
<Condition>
The alarm occurs when the controller’s internal data or parameters are
abnormal.
<Countermeasure>
If the problem is not solved by supplying power again, please contact SMC.
C
Stopped
RESET input
is ON
(Press setting
button)
<Condition>
The alarm occurs when the return to origin, positioning or a jog operation is
commanded when the electric actuator is servo off state.
<Countermeasure>
Check if I/O signal STOP is input.Also, check if the servo off in manual mode.
Refer to
8.5 Servo ON
for turning servo off.
C
Stopped
RESET input
is ON

Check if the operating condition of the electric actuator is within the specification
range.
Caution
If the power supply is an inrush current suppressor type, a voltage drop may
occur during acceleration / deceleration, generating an alarm.
