！ Caution: Follow the notes below to avoid an electric shock.
their specifications for Motor size and maximum Motor torque match
each other.
à Refer to "2.4.Standard Combination List" for the combination.
à This is because the Driver Unit holds the unique parameter settings for the Motor in it.
à Confirm that the reference numbers on each identification plate of a Motor and a
Driver Unit indicate the sane Motor size code, Motor maximum torque and position
sensor code.
à If the numbers are different, the System will lose its accuracy, and emit noise, and
furthermore, the Motor won't move, or may lose control.

à If disassembled, it may cause abnormalities such as deterioration in rigidity and
positioning accuracy as well as increase in noise.
the control I/O connector.
à Please set the System so that you can immediately stop the Motor in case of an
emergency.
à The Driver Units have high capacity conductors in its internal circuits, thus resulting in
high residual voltage of the capacitors for few minutes after the main power is turned
off.
à Do not detach a cover of a Driver Unit unless it is necessary.
à When the cover has to be removed, follow the procedures bellow.
