speed setting.
Note
• When extending the I/O signals cable, the length must not exceed 2 m
(6.6 ft.). To minimize noise, it should be as short as possible.
• The I/O signals cable must be located 200 mm (8 in.) or more away from
such inductive loads as electromagnetic relay, and must cross power supply
and motor cables, not parallel to them.
• If you are not using all cables from the terminals provided on the
non-connector side of the I/O signals cable, insulate the unused cables to
prevent them from contacting other devices, or depending on the
applications of these signals connect them to 5 VDC from a user-provided
external control device or to a signal ground.
