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) 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
8) 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
9) 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
10) Actuator mouting condition is not
good.
Check the actuator mounting surface.
Keep the flatness of mounting surace
to within 0.2mm or less.
Operation not completed
/ During operation
(Not always, but may happen
occasionally)
Alarm for “Step data ALM2/code:
1-051” is generated.
↓
<Procedure of restart>
Input the “reset” signal.
1) Command invalid (unregistered)
step data.
Check if the step data is valid
(registered).
2) Different input signal to the
expected step number is inputted to
the controller, because of a too short
an interval between the input signal of
“IN*” and the “Drive” or inputting the
signals at the same time.
Add an interval of 15ms (the
recommendation is 30ms) or more
between the input signals.
/
See “Operating procedure input / output
signals for each operation type” on page 21
3) Different input signal to the
expected step number is inputted to
the controller, because the input
signal time was too short.
Add an interval of 15ms (the
recommendation is 30ms) or more
between the input signals.
/
See “Operating procedure input / output
signals for each operation type” on page 21
4) Different input signal to the
expected step number is inputted to
the controller, caused by PLC or
other device.
Check that the step number is
inputted correctly for the required
motion.
- Operation completed by
unexpected motion.
- No alarm
