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.

33.DIGITAL INPUT #3 FUNCTION

USE PARAMETER #33 TO SELECT THE #3 DIGITAL INPUT FUNCTION.

RANGE OF VALUES: 0000 0000h to 0001 000Fh no decimal significance

Default Value: 0001 0003h no decimal 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 no decimal significance

Default Value: 0001 0004h no decimal significance

The setting options are the same as parameter #31. The default, by factory setting, is 0001 0004h, which is an DOWN (decrease) input which must have +24VDC applied with respect to TB2:A1 to be active.
