condition of
the
controller
when an
alarm is
generated
How to
clear
the
alarm
Condition / Countermeasure
<Condition>
Positioning of the polarity is not finished properly. When the power is
supplied, the actuator slightly moves to detect the polarity of the motor.
This alarm is generated when the actuator cannot be moved.
E
When the
power is
supplied
Power
supply
for
control
is
turned
off
<Countermeasure>
Supply power in conditions in which the actuator is operable.
<Condition>
An abnormality is confirmed with the current sensors which are
recognized when the controller is initialized.
E
When the
power is
supplied
Power
supply
for
control
is
turned
off
<Countermeasure>
Confirm the combination of the controller and the actuator is correct. If
the problem is not solved by supplying power again, please contact
SMC.
<Condition>
Position deviation counter in the controller has overflowed.
E
During
operation
Power
supply
for
control
is
turned
off
<Countermeasure>
Check if the travel of the actuator is interrupted. Check if the load of the
actuator is within the specification range.
<Condition>
Output current at the power supply circuit is abnormally high.
E
Any
condition
Power
supply
for
control
is
turned
off
<Countermeasure>
Check if the actuator cable or connector is short-circuited.
Confirm the combination of the controller and the actuator is correct.
<Condition>
Abnormality concerning EEPROM is confirmed.
E
Any
condition
Power
supply
for
control
is
turned
off
<Countermeasure>
If the problem is not solved by supplying power again, please contact
us.
（
The write limit of the EEPROM is roughly 100,000 times
）
<Condition>
CPU is not operating properly. (Failure of CPU and peripheral circuits,
or malfunction due to noise)
E
Any
condition
