Operation not completed
/ Operation continue
Alarm for “Over load/code: 1-148”
or “Posn failed/code: 1-149” is
generated.
↓
<Procedure of restart>
Controller version /SV1.0 or later
1. Input the “reset signal.”
“SVRE”: Automatically ON
Controller version /SV0.8* or before
1. Input the “reset signal.”
“SVRE”: Automatically ON
2. Input the “setup signal.”
Restart operation after the
completion of the”retun to origin”.
1) Added excessive external force
(including vibration) or impact
load.
Operate within the specified range.
/See 2.1 Specifications on page 9
2) The Power supply does not have
sufficient capacity.
Check the power consumption for
each actuator and controller:
If necessary replace the existing
power supply with a power supply
with sufficient capacity.
/See 2.1 Specifications on page 9
3) Load/resistance more than
specified range is being applied to
the actuator.
Use within specification range.
Check the actuator mounting
condition or check if external force
adds the resistance of actuator table
by using movable cable-duct.
/See 2.1 Specifications on page 9
4) Pushing operation is performed
at “Positioning operation”
Review the content of the step data.
5) The cable is not connected
or has been disconnected.
Confirm that the cable is connected
correctly.
/See 4. Wiring of cable on page 26
6) It was not the intended origin
position because the actuator
pinched the work-piece during
the“return to origin”.
Remove the work-piece and restart
the return to the intended origin
position.
7) Actuator mouting condition is not
good.
Check the actuator mounting surface.
Keep the flatness of mounting
surace to within 0.2mm or less.
8) Wrong input [0] is input as the
positioning force.
Check the step data.<Moving force>
/See 3.3.Step data setting method
on page 17
9) The step data position is not
changed correctly after the return
to origin direction is changed.
Check the step data.<Position>
/See 3.3.Step data setting method
on page 17
10) Because the operation of the
step data is set to [INC/relative],
the table comes into contact with
an external object and does not
move due to continuous operation.
Check the step data.<Position>
/See 3.3.Step data setting method
on page 17
Operation not completed
/ Operation continue
Alarm for “Stroke limit/code: 1-052”
is generated.
↓
<Procedure of restart>
Input the “RESET” signal.
1) Moving distance exceeds the
“Stroke (+)” / “Stroke (-).
1) Check the value of the “Position”
of step data and the value of the
“Stroke (+)” / “Stroke (-)” of the basic
parameter.
/See 3.3.Step data setting method
on page 17
