Input
(*1)
<Contents> The output current accumulated value exceeds
the specified value.
<Countermeasure> Check whether the movement of the
actuator is obstructed.Also confirm whether the actuator load,
speed, acceleration and deceleration are within the
specification range of the actuator.
<Contents> Failed to reach to the set position within the set time
limit.

SVON
Input
(*1)
<Countermeasure> Eliminate any obstructions that interfere
with the actuator movement.
Also, make sure that the load, speed, acceleration and
deceleration are within the range of the actuators.
<Contents> The connection with the higher-level devices
(such as the PC and teaching box) is disconnected.

D
RESET
SVON
Input
(*1)
<Countermeasure> Make sure that the higher-level devices
will not be disconnected during the actuator operation.
<Contents> Abnormality in communication with the encoder.
Encoder ALM
(1-192)
E Power off
<Countermeasure> Check the connection of the actuator
cable.
<Contents> Unable to find the motor phase within the set time.
(When the servo motor is turned on (SVON is turned on) first
time after the power is applied, the actuator needs to move a
little to find the motor phase. However, if this actuator
movement is prevented, this alarm will be activated.)
Phase Det ALM
(1-193)
E Power off
<Countermeasure> Make sure there are no obstructions that
interfere with the actuator movement and then, turn on the
servo motor (SVON is turned on).
<Contents> The output current of the power circuit is
extraordinarily high.
Over current
(1-194)
E Power off
<Countermeasure> Make sure that there are no short circuits
of actuator cables, connectors, etc. In addition, make sure that
the actuator conforms to the controller.
<Contents> An abnormality is detected by the current sensor
that is checked when the controller is reset.
I sens ALM
(1-195)
E Power off
<Countermeasure> Make sure that the actuator conforms to
the controller. Even after this measure, if the alarm
regenerates when the power is reapplied, please contact SMC.
<Contents> An overflow of the position error counter inside of
the controller is occurred.
Err overflow
(1-196)
E Power off
<Countermeasure> Make sure there are no obstructions that
interfere with the actuator movement. Also, make sure that the
load, speed, acceleration and deceleration are within the range
of the actuators.
<Contents> An error of the EEPROM is occurred.
Memory ALM
(1-197)
E Power off
<Countermeasure> Please contact SMC.
<Contents> The CPU is not operating normally.
(It is possible that the CPU or surrounding circuits is failed or a
malfunction of the CPU is occurred due to an electric noise).
CPU ALM
(1-198)
E Power off
<Countermeasure> If the alarm cannot be deactivated even
after the power is reapplied, please contact SMC.
