“INP” output signal is unstable.
Positioning completion signal [INP]
is not outputted.
1) The value of [In position] in
step data is too small.
Check the step data.
<In Pos>
(Minimum value:0.5)
/
See “Step data setting” on p.22
“INP” output signal is [OFF].
“
INP” output signal is [OFF] even
after the pushing operation is
completed.
1)The value of "In pos" is input
forward of work.
Input the value of "In pos" larger
than length to work.

See “Example of step data entry
(3)” on p.27
5
Positioning repeatability is out of
specified range.
1) It shifts to the next operation by
receiving the "INP" output
signal.
Go to the next operation after
receiving
the “BUSY” output
signal is outputted.
6
The operation time is delayed to
the step date setting.
1) The inertia moment-angle
acceleration and deceleration
and effective torque - angular
speed exceed the specified
range.
Check this with the model
selection stated in the catalog.
7
Damage
1) Abnormal external force
Interference of mechanism,
eccentric load or excess load
leads to cause deformation or
damage of the actuator. Eliminate
these factors.
8
The rod of the actuator with vertical
mounting vibrates repeated up and
down.
1) The inertia moment-angle
acceleration and deceleration
and effective torque - angular
speed exceed the specified
range.
Check this with the model
selection stated in the catalog.
