Encoder

 

(optional)

 

The

 

PMAC

 

3000

 

is

 

available

 

with

 

an

 

encoder

 

option.

  

This

 

option

 

is

 

easily

 

verified

 

at

 

power

 

up

 

when

 

the

 

software

 

version

 

is

 

displayed

 

in

 

the

 

Startup

 

Screen.

  

See

 

Figure

 

2.

  

At

 

the

 

end

 

of

 

the

 

software

 

version,

 

“

‐

E”

 

will

 

appear.

 

The

 

encoder

 

version

 

works

 

with

 

quadrature

 

encoders

 

with

 

single

 

ended

 

TTL/CMOS

 

outputs.

  

It

 

powers

 

the

 

encoder

 

with

 

5VDC.

 

There

 

are

 

three

 

modes

 

of

 

operation

 

that

 

relate

 

to

 

the

 

encoder.

  

These

 

modes

 

are

 

Off,

 

Angle

 

and

 

RPM.

  

How

 

to

 

select

 

the

 

appropriate

 

mode

 

is

 

discussed

 

in

 

the

 

Menu

 

section

 

later

 

in

 

this

 

manual.

  

In

 

the

 

Off

 

mode,

 

the

 

PMAC

 

3000

 

behaves

 

just

 

like

 

it

 

would

 

with

 

the

 

standard

 

software

 

(no

 

encoder

 

software).

  

In

 

the

 

Angle

 

mode,

 

all

 

encoder

 

measurements

 

are

 

made

 

in

 

degrees.

  

In

 

the

 

RPM

 

mode,

 

all

 

encoder

 

measurements

 

are

 

made

 

in

 

RPM.

  

In

 

the

 

case

 

of

 

Angle

 

and

 

RPM

 

modes,

 

the

 

display

 

is

 

split

 

such

 

that

 

the

 

sensor

 

reading

 

is

 

on

 

the

 

left

 

and

 

the

 

encoder

 

reading

 

on

 

the

 

right.

  

The

 

appropriate

 

units

 

are

 

shown

 

below

 

the

 

corresponding

 

reading.

 

The

 

encoder

 

version

 

provides

 

for

 

encoder

 

limits,

 

just

 

like

 

those

 

provided

 

for

 

the

 

load

 

sensor.

  

These

 

limits

 

are

 

Low,

 

Ok,

 

High

 

and

 

Target.

  

In

 

each

 

case,

 

they

 

are

 

evaluated

 

in

 

the

 

same

 

way

 

that

 

the

 

sensor

 

limits

 

are

 

evaluated.

  

In

 

the

 

various

 

Peak

 

modes,

 

all

 

the

 

limits

 

are

 

evaluated

 

after

 

the

 

process

 

concludes,

 

while

 

the

 

Target

 

limit

 

is

 

evaluated

 

in

 

real

 

time.

  

In

 

the

 

Record

 

modes,

 

only

 

the

 

Target

 

limit

 

is

 

evaluated.

  

As

 

before,

 

in

 

the

 

Record

 

modes,

 

the

 

Target

 

limit

 

is

 

evaluated

 

in

 

real

 

time.

  

In

 

the

 

Track

 

mode,

 

all

 

limits

 

are

 

evaluated

 

in

 

real

 

time.

 

In

 

the

 

Track

 

mode,

 

Angle

 

begins

 

counting

 

immediately

 

and

 

may

 

be

 

reset

 

to

 

zero

 

by

 

pressing

 

the

 

Tare

 

button.

  

Note

 

that

 

pressing

 

the

 

Tare

 

button

 

also

 

zero’s

 

the

 

sensor

 

when

 

running

 

in

 

Relative

 

mode.

  

RPM,

 

by

 

its

 

nature,

 

cannot

 

be

 

zeroed.

 

In

 

the

 

Peak

 

modes,

 

Angle

 

begins

 

counting

 

from

 

zero

 

as

 

soon

 

as

 

the

 

sensor

 

load

 

has

 

crossed

 

the

 

Threshold

 

value

 

and

 

a

 

new

 

cycle

 

has

 

started.

  

As

 

before,

 

if

 

the

 

sensor

 

load

 

exceeds

 

the

 

Target

 

level,

 

the

 

target

 

output

 

will

 

fire.

  

In

 

Angle

 

mode,

 

any

 

Angle

 

reading

 

exceeding

 

the

 

encoder

 

Target

 

value

 

will

 

also

 

cause

 

the

 

Target

 

output

 

to

 

fire.

  

After

 

the

 

cycle

 

completes,

 

the

 

sensor

 

value

 

is

 

evaluated

 

with

 

respect

 

to

 

the

 

sensor

 

limits,

 

and

 

the

 

Angle

 

value

 

is

 

evaluated

 

with

 

respect

 

to

 

the

 

encoder

 

limits.

  

In

 

RPM

 

mode,

 

the

 

RPM

 

is

 

monitored

 

throughout

 

the

 

Peak

 

cycle,

 

but

 

the

 

RPM

 

is

 

not

 

zeroed

 

at

 

the

 

start

 

of

 

it.

  

As

 

in

 

Angle

 

mode,

 

if

 

the

 

RPM

 

value

 

exceeds

 

the

 

encoder

 

Target

 

value,

 

the

 

Target

 

output

 

will

 

fire.

  

After

 

the

 

cycle

 

is

 

complete,

 

the

 

RPM

 

value

 

is

 

evaluated

 

with

 

respect

 

to

 

the

 

encoder

 

limits.

  

In

 

either

 

case,

 

Angle

 

or

 

RPM

 

mode,

 

an

 

encoder

 

limit

 

failure

 

will

 

trigger

 

the

 

corresponding

 

output

 

and

 

will

 

light

 

the

 

corresponding

 

limit

 

indicator

 

on

 

the

 

front

 

panel.

  

It

 

is

 

therefore

 

possible

 

to

 

have

 

a

 

High

 

Limit

 

and

 

Low

 

Limit

 

violation

 

at

 

the

 

same

 

time

 

if

 

the

 

sensor

 

violates

 

one

 

of

 

its

 

limits

 

and

 

the

 

encoder

 

violates

 

the

 

other.

  

Note

 

that,

 

in

 

the

 

Peak

 

modes,

 

the

 

encoder

 

value

 

that

 

is

 

captured

 

and

 

evaluated

 

with

 

respect

 

to

 

the

 

High

 

and

 

Low

 

Limits

 

is

 

the

 

value

 

that

 

coincides

 

with

 

the

 

peak

 

value

 

from

 

the

 

sensor.

  

The

 

encoder

 

value
