Over load
(1-148)
D
RESET
SVON
Input
*1)
<Contents>
The output current accumulated value exceeds the specified
value.
<Countermeasure>
Check whether the movement of the electric actuator is
obstructed. Also confirm whether the electric actuator load,
speed, acceleration and deceleration are within the
specification range of the electric actuator.
Posn failed
(1-149)
D
RESET
SVON
Input
*1)
<Contents>
Failed to reach to the set position within the set time limit.
<Countermeasure>
Eliminate any obstructions that interfere with the electric
actuator movement.
Also, make sure that the load, speed, acceleration and
deceleration are within the range of the
electric actuators.
Ctrl Comm ALM
(1-150)
D
RESET
SVON
Input
*1)
<Contents>
The connection with the higher-level devices (such as the PC
and teaching box) is disconnected.
<Countermeasure>
Do not remove the cable during operation by the controller
setting kit or teaching box.
Encoder ALM
(1-192)
E
Power off
<Contents>
Abnormality in communication with the encoder.
<Countermeasure>
Check the connection of the actuator cable.
Phase Det ALM
(1-193)
E
Power off
<Contents>
Unable to find the motor phase within the set time.
(When the servomotor is turned on (SVON is turned on) first
time after the power is applied, the
electric actuator needs to
move a little to find the motor phase. However, if this
electric
actuator movement is prevented, this alarm will be activated.)
<Countermeasure>
Make sure there are no obstructions that interfere with the
electric actuator movement and then, turn on the servomotor
(SVON is turned on).
Over current
(1-194)
E
Power off
<Contents>
The output current of the power circuit is extraordinarily high.
<Countermeasure>
Make sure that there are no short circuits of the electric actuator
cables, connectors, etc. In addition, make sure that the electric
actuator conforms to the controller.
I sens ALM
(1-195)
E
Power off
<Contents>
An abnormality is detected by the current sensor that is
checked when the controller is reset.
<Countermeasure>
Make sure that the electric actuator conforms to the controller.
When a command to turn on servo is given, check if BK RLS is
energized by installing the electric actuator vertically in order to
check if the motor is driven by an external force.
Even after this measure, if the alarm regenerates when the
power is reapplied, please contact SMC.
