A “0 = Not Stop” condition (logic 0) must first be present before a “1 = Start” condition will start the drive. The Start command acts as
a momentary Start command. A “1” will start the drive, but returning to “0” will not stop the drive.

Depending on the PowerFlex 4-Class drive, the functions for bits 6, 7, and 15 change. Refer to Appendix C in the PowerFlex 4,
PowerFlex 4M, PowerFlex 40 or PowerFlex 40P drive User Manual, or Appendix E for the PowerFlex 400 drive bit functions.
(3)
The functions for these bits are the same for all PowerFlex 4-Class drives—including the PowerFlex 40P when it is used in the
“Velocity” mode. When using the PowerFlex 40P in the “Position” mode, the bit functions are different. For details, see Appendix C in
the PowerFlex 40P User Manual.
