D
Any
condition
RESET
input is ON
(Press setting
button)
<Condition>
The temperature around the power element of the controller is too high.
<Countermeasure>
Improve the peripheral environment of the controller after checking the installation
of the controller.
Refer to
3.4 How to install
for the mounting conditions of the controller.
D
Any
condition
RESET
input is ON
(Press setting
button)
<Condition>
It occurs when the control power supply voltage detected inside the controller falls
outside the specified range
<Countermeasure>
Please check the voltage supplied to the control power supply (C24V) of the
controller.
Caution
If a single power supply is used for both the control power and the motor power,
or the power supply is “inrush current suppression type”, a power voltage drop
may occur during acceleration / deceleration, generating an alarm.
D
During or
after
suspension
of
operation
RESET
input is ON
(Press setting
button)
<Condition>
The time to reach the target position is longer than the specified value.
<Countermeasure>
Check that the electric
actuator’s move is not interrupted.
If you are adjusting the stopper, perform stroke learning and re-registration of all
intermediate positions.
E
Immediately
after
turning on
the power
Control
power
supply is
shut down
<Condition>
This alarm occurs when an abnormality is detected in the encoder signals.
<Countermeasure>
Please check whether there are any loose connections or any damage to the
connector of the controller and / or electric actuator. Please check whether there
is any damage to the actuator cable (severed wires, etc.).
E
Immediately
after
turning on
the power
Control
power
supply is
shut down
<Condition>
Positioning of the polarity is not finished properly. When the power is supplied, the
electric actuator slightly moves to detect the polarity of the motor. This alarm is
generated when the electric actuator cannot be moved.
<Countermeasure>
Supply power in conditions in which the electric actuator is operable.
E
Immediately
after
turning on
the power
Control
power
supply is
shut down
<Condition>
An abnormality is confirmed with the current sensors which are recognized when
the controller is initialized.
<Countermeasure>
Please check that the motor is not operated by external force during servo ON.
Install the electric actuator vertically and check that the BK RLS is not energized.
Confirm the combination of the controller and the electric actuator is correct.
If the problem is not solved by supplying power again, please contact SMC.
E
During
operation
Control
power
supply is
shut down
<Condition>
Position deviation counter in the controller has overflowed.
<Countermeasure>
Check that the electric
actuator’s move is not interrupted.
Check if the load of the electric actuator is within the specification range.
