31. DIGITAL INPUT #1 FUNCTION
USE PARAMETER #31 TO SELECT THE #1
DIGITAL INPUT FUNCTION.
RANGE OF VALUES: 0000 0000h to 0001 000Fh
no decimal significance
Default Value: 0001 0001h no decimal
significance
VL4 and VL2 are always 00. VL1 determines
function of the input. The following are predefined:
00h General Purpose Input
01h Run Input
02h Preset Input
03h Up Input
04h Down Input
05h Reverse Input
06h Frequency Mode
07h Remote Input
08h Master/Slave (not functional at present)
09h Jog
0Ah Preset 2
0Bh Contactor Aux
0Ch through 0Fh Not Assigned, selection
will cause input to be General Purpose
Input.
Any digital input may be assigned to any
function. The factory defaults are included for testing
purposes, to provide a baseline setup, and to be able
to run the DFS-1 the first time before programming.
VL3 contains the polarity flag, which is either
00h or 01h. A 01h setting means that +24VDC must
be applied to the input to make it active. A 00h
setting means the input is active with no voltage
applied.
A Digital Input may get its +24VDC signal from
any source with TB2:A1 common, and may be any
parameter, transducer, or switch at which the pro-
gram or communications wishes to look.
The default, by factory setting, is 0001 0001h,
which is a run input which must have +24VDC
applied with respect to TB2:A1 to be active.
32. DIGITAL INPUT #2 FUNCTION
USE PARAMETER #32 TO SELECT THE #2
DIGITAL INPUT FUNCTION.
RANGE OF VALUES: 0000 0000h to 0001 000Fh
no decimal significance
Default Value: 0001 0002h no decimal
significance
The setting options are the same as parameter
#31. The default, by factory setting, is 0001 0002h,
which is a preset input which must have +24VDC
applied with respect to TB2:A1 to be active.

significance
The setting options are the same as parameter
#31. The default, by factory setting, is 0001 0003h,
which is an UP (increase) input which must have
+24VDC applied with respect to TB2:A to be active.
34. DIGITAL INPUT #4
FUNCTION
USE PARAMETER #34 TO SELECT THE #4
DIGITAL INPUT FUNCTION.
RANGE OF VALUES: 0000 0000h to 0001 000Fh
