4-4 Understanding the I/O Image

The Logic Command is a 16-bit word of control data produced by the

controller and consumed by the 1769-SM2 module. The Logic Status is a

16-bit word of status data produced by the 1769-SM2 module and

consumed by the controller.

This manual contains the bit definitions for compatible products

available at the time of publication in Appendix

D. For other products,

refer to their documentation.

The Reference (16 bits) is produced by the controller and consumed by

the 1769-SM2 module. The Feedback (16 bits) is produced by the

1769-SM2 module and consumed by the controller.

Valid Reference/Feedback values for PowerFlex 4-Class drives are:

The Reference/Feedback for a PowerFlex 4-Class drive is set in Hz and

not in engineering units like PowerFlex 7-Class drives. For example,

“300” equates to 30.0 Hz (the decimal point is always implied) for all

PowerFlex 4-Class drives—except PowerFlex 400 for which “3000”

equates to 30.00 Hz. In all cases, a minus value equates to reverse

motor direction, and a plus value equates to forward motor direction.
