Chapter 1 Drive Comparisons

PowerFlex DC Drive

PowerFlex DC 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”.

Additional digital and analog I/O is available when using the optional I/O

Expansion circuit board. Refer to Appendix F - “Optional Analog and Digital I/

O Expansion Circuit Board”, in the PowerFlex Digital DC Drive User Manual,

publication 20P-UM001

, 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. Refer to Appendix G - “Optional 115V AC to 24V DC I/O

Converter Circuit Board” in the PowerFlex Digital DC Drive User Manual,

publication 20P-UM001

, for more information. All I/O terminal blocks are

located on the control board.

±10V / 0-20mA, or 4-20mA.

Important: 0-20mA or 4-20mA 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. Refer to “DIP Switch and

Jumper Settings” in the PowerFlex Digital DC Drive
