Unable to
find motor
phase in set
time.

E
Turn off the
main control
and motor
control
power
supplies.
< Details >
Positioning of the polarity is not completed properly.
(When the servo motor is turned on (SVON is ON) for the
first time after the power is supplied, the actuator needs to
move a little to find the motor phase.If this actuator
movement is prevented, an alarm will be generated).
<Countermeasure>
Make sure there are no obstructions that interfere with the
actuator movement and then turn on the servo motor
(SVON is ON).

E
Turn off the
main control
and motor
control
power
supplies.
< Details >
The Output current in the power supply circuit is abnormally high.
<Countermeasure>
Check if the actuator cable or connector is short-circuited.
In addition, make sure that the actuator is compatible with
the controller.
Current
sensor
abnormality
has
occurred.
(1-195)
E
Turn off the
main control
and motor
control
power
supplies.
< Details >
An abnormality with the current sensors is detected, which
is recognized when the controller is initialized.
<Countermeasure>
Confirm the combination of the controller and the actuator
is correct. If the alarm is still generated when the power is
reapplied, please contact SMC.
Position
error
overflowed
(1-196)
E
Turn off the
main control
and motor
control
power
supplies.
< Details >
The position deviation counter in the controller has
overflowed.
<Countermeasure>
Check if the travel of the actuator was interrupted. Also,
make sure that the load, speed, acceleration and
deceleration are within the specifications of the actuator.
Memory
abnormality
has
occurred
(1-197)
E
Turn off the
main control
and motor
control
power
supplies.
< Details >

Please contact SMC. (The write limit of the EEPROM is
approximately100,000 times)
CPU error
(1-198)
E
Turn off the
main control
and motor
control
power
supplies.
< Details >
