* 1: Be careful that the specifications may be changed without notice.
2: The maximum transmission distance depends on size of cable wire. Use the
following recommended cable or equivalent:
Model M-53004 of Reliance Electric (size of wire 0.05 square millimeters,
twisted pair, seven pairs are shielded as a lot)
The above-mentioned maximum transmission distance of 200 meters is
obtained when the above cable is used.
3: When power wiring for encoders is installed in a same conduit, be careful to
acquire the required voltage at the encoders, considering voltage drop due
to cable length.
