I/O Signal and Control Wiring
Eight (8) digital inputs, four (4) digital outputs, three (3) analog inputs, and two
(2) analog outputs are available on the standard I/O terminal blocks provided
with the drive. One digital input (1…8) must be configured for “Enable” (digital
input 4 by default = “Enable”). See I/O and Control Wire Routing on page
for information on routing I/O signal and control wires.
Additional digital and analog I/O is available when using the optional I/O
Expansion circuit board. See
for more information. Also, you can use
the optional 115V AC Converter circuit board to convert 115V AC digital input
signals to 24V DC digital inputs signals to interface with the digital inputs on the
standard I/O terminal blocks. See
for more information.

Important: 0…20 mA or 4…20 mA operation
requires that switch S9, S10, and S11 on the control
board be in the “Off” position. Drive damage may
occur if the switch is not in the correct position based
on the type of input signal. See
