Installation/Wiring
Control I/O Wiring Block Diagram Notes
(1) See
Digital Input Selection for Start Source on page 47
for more information on configuring the digital inputs.
(2) Two wire control shown. For three wire control use a momentary input
on I/O Terminal 02 to command a start. Use a
maintained input
for I/O Terminal 03 to change direction.
(3) When using an opto output with an inductive load such as a relay, install a recovery diode parallel to the relay as shown, to prevent
damage to the output.
IMPORTANT
I/O Terminal 01 is always a stop input. The stopping mode is determined by the
drive setting. See the tables below for more information.

IMPORTANT
The drive is shipped with a jumper installed between I/O Terminals 01 and 11.
Remove this jumper when using I/O Terminal 01 as a stop or enable input.

Stop
Coast
Three wire stop. However, it functions as a stop under all input
modes and cannot be disabled.

DigIn TermBlk 02/
Start/Run FWD
Run FWD
Used to initiate motion and also can be used as a programmable
digital input. It can be programmed with t062 [DigIn TermBlk
02] as three wire (Start/Dir with Stop) or two wire (Run FWD/
Run REV) control. Current consumption is 6 mA.

DigIn TermBlk 03/
Dir/Run REV
Run REV
Used to initiate motion and also can be used as a programmable
digital input. It can be programmed with t063 [DigIn TermBlk
03] as three wire (Start/Dir with Stop) or two wire (Run FWD/
Run REV) control. Current consumption is 6 mA.
