Input/Output
The PowerFlex 700 drive has standard I/O embedded on the main control board.
The voltage of this I/O can be determined by the catalog string position ‘k’.
See PowerFlex Drive Catalog Numbers
on page 46. The PowerFlex 755 drive
contains one digital input on the main control board and uses the optional 750-
Series I/O Modules for additional I/O. The PowerFlex 753 contains some I/O
resident to the main control board and also uses optional I/O.
