Caution: y No retaining torque is provided in automatic servo OFF. Pay sufficient
attention to the setting because the actuator may be moved by external force
applied to it.
y
Do not use the automatic servo OFF if the next moving command is relative
distance specification (pitch feed). Failure to follow it may cause position shift
to occur.
y
