(2) Load was not contacted (missed)
(1) After reaching the target position, the
actuator will move at low speed (75
rpms).
Even after contacting the load, the
actuator will move to the end of the
positioning band if the stepper motor
current is yet to reach the current-limiting
value.
The position complete output will not turn
ON even when the end of the positioning
band is reached. In this case, only the
completed position number will be output.
(Provide a timeout check process after a
sufficient period with a PLC.)
(3) Load moves during push & hold operation
(a) Load moves in the pushed direction
If the load moves in the pushed direction
after the position complete output has turned
ON, the actuator will push the load within the
positioning band.
The position complete output will remain ON
and the completed position number will be
output continuously.
(b) Load moves in the opposite direction
(Actuator is pushed back by the reactive force of the load)
If the actuator is pushed back after the
position complete output has turned ON
because the actuator thrust is smaller than
the reactive force of the load, the actuator
will be pushed back all the way until its thrust
balances out with the reactive force of the
load. The position complete output will
remain ON and the completed position
number will be output continuously.
