Appendix N

Limit Switches and Home Switches

6

The

VXM

by

default

recognizes

normally

closed

(N/C

to

run)

limit

switches.

The

default

mode

is

auto-detect

normally

closed

switches.

If

the

VXM

is

used

with

normally

open

or

with

a

home

switch,

the

limit

switch

mode

will

need

to

be

changed.

The

following

command

sets

the

operating

mode

of

the

limit

inputs.

It

is

important

to

understand

how

a

home

switch

works,

and

what

programming

procedure

to

use

to

get

a

high

degree

of

precision

and

accuracy

obtainable

by

these

switches.

Repeatability

of

1

motor

step

is

achievable

if

the

proper

procedures

are

followed

when

referencing

to

a

home

switch.

The

most

common

home

switch

used

on

rotary

tables

is

a

magnetic

reed

type

sensor.

The

magnetic

sensor

is

usually

connected

directly

to

the

positive

and

negative

limit

switch

inputs

on

the

VXM.

Home

switches

have

an

active

area

of

several

degrees.

Because

of

this

large

area

where

the

switch

is

activated,

it

is

important

to

always

approach

the

switch

from

the

same

direction

when

homing.
