This

section

discusses

methods

of

establishing

loops

in

the

programs

you

write

for

you

application. Loops

can

be

created

individually

or

nested

within

each

other.

You

may

use

the

Loop

(L)

command

to

repeat

certain

programs

the

one

provided below. All

the

commands

between

the

L

command

and

the

N

command

are

looped (repeated)

the

number

of

times

indicated

in

the

L

command.

You

can

use

the

Immediate

Pause

(01

command

to

temporarily

halt

execution

of

the

loop while

it

is

in

progress.

Description

Pauses command execution until the indexer

receives a Continue (C) command

Sets mode to incremental

Sets move to normal mode

Sets acceleration to 5 revs/sec

Sets velocity to 5 rps

Performs the Loop 5 times

Sets distance to 12,800 steps

Executes the move (Go)

Delays

2 seconds after the move

Ends Loop

Initiates command execution

The

moves

a

total

of

64.000

steps

(a

succession

of

five

12.800-step

moves

with a

2-second

pause

between

each

move).

The

example

below

shows

how

you

can

nest

a sma11loop

inside

a

major

loop.

The

only

way

you

can

nest

a loop

is

by

using

the

Constant

Velocity Loop

(CL)

and

End

Loop

(CN)

commands

in

the

continuous

mode

(MC).

You

may

nest

a

constant

velocity loop

within

a

standard

loop.

but

not

within

another

CL loop.

The

following

sequence

then

turns

then

off.

You

can

issue

the

Stop

Loop (Y)

command

to

terminate

both

loops.
