MP450S Operator Manual

Chapter 1: Introduction

Overview

The AMS Controls MP450S is an industrial controller used to control cut-to-

length machinery equipped with slitting knives. Figure 1 shows the front panel of

MP450S.

Figure 1: The AMS Controls MP450S Controller

Features

The MP450S controller’s features include:

•Accurate length control

•Simple programming

•Automatic stops for knife changes

•Easy calibration

Chapter 2: Manual Operations

Jogging Material

•To jog material forward using the MP450S, turn the jog switch on the

controller to the right (clockwise).

•To jog material in reverse using the MP450S, turn the jog switch on the

controller to the left (counter-clockwise).

Manual Shear

To fire the shear manually, press the shear button .

Note: The controller must be in Manual mode.

Load a Coil (Autoload Feature)

To load a new coil,

1. Press [Halt] to ensure the machine is in the manual mode.

2. Turn the [Jog] switch to forward and hold it in place. The material feeds

through the machine and stops automatically when the leading edge is just

past the shear blade.

3. Press the [Shear] button and trim cut the leading edge of the coil. The

material is cut and the controller’s length display re-sets to zero.

The machine is now ready to produce parts.

Procedures

Screen Navigation

Keypad

The keypad uses hot keys to enable quick entry into certain screens.

Program Press [Program] to program a Job Number, Quantity, and

Length; press it again to specify the next job to run.

Status Press [Status] to exit the current screen and return to the

Status screen.

Calibration Press [Calibration] to calibrate the length management

system; press it again to display the Footage Totalizer.

•To reset the totalizer to zero: When the footage

displays, press [Clear]. The prompt “Enter Code to

Clear Total” displays; enter 1984 and press [Enter].

Enter Press [Enter] to enter or store the current value. [Enter]

can also be used to move to the next value.

Clear Press [Clear] (clear entry) to clear or set an entry back to

its original value.

Push Button and Front Panel Selector Switches

Shear Press [Shear] to manually activate the shear.

Note: The MP450S controller allows this switch to

operate when the machine is stopped.

Halt Select [Halt] to load a coil and to stop the machine

MP450S Operator Manual

Run Select [Run] to start the machine after a job has been

programmed

Jog

(Forward

and

Reverse)

When the machine is in manual mode (i.e., the Run

button is not lit), turn and hold the Jog switch

clockwise to jog the material forward, turn and hold the

Jog switch counter-clockwise to jog the material in

reverse.

This switch is inactive when the Run switch is lit.

Power This switch turns the controller on and off.

•Turn the switch to the right to apply power to the

controller unit

•Turn the switch to the left to remove power

Note: If the controller unit has been wired to by-pass this switch, the position

of the switch will have no affect on the controller.

Program a Job

Jobs are composed of a quantity of a specified length. You can program up to 50

different quantities and lengths into the controller. To program a job,

1. Select [Program] . The current data entry field highlights; once new data

has been entered, the data field starts blinking.

Note: Pressing [Clear] while the data field is blinking re-loads the

original value into the data field. Pressing [Enter] saves new data

and highlights the next field.

2. In the Job Number field, enter a number to assign to this job (a value

between 1 and 50).

3. In the Quantity field, enter the number of parts you want to create (up to

999).

4. In the Length field, up to 999 feet and 11.999 inches.

MP450S Operator Manual

5. The controller displays the message “Pause After Job xx?” (where xx is the

job number assigned in step 1). Select:

-Yes to have the machine halt automatically after the selected job number

is finished.

-No to have the machine change lengths “on-the-fly” and run the job

following the selected job without first stopping.

Note: To restart the machine after an automatic halt, press [Run].

6. The controller displays the message “Raise Knives after Job xx?” ” (where xx

is the job number assigned in step 1). Select:

-Yes to require the operator to raise the knife blades prior to completing

the last part. On the last part, the line stops at a position equal to the

part length minus the knife distance. The operator is then required to

raise the knife blades and press [Run] to complete the final parts. This

option is used to prevent scrap waste.

Note: When making parts shorter than the knife distance, it is

possible that the knife blades are required to be in the up position

in order to complete multiple parts.

For example, assume the knife distance is set to 24 inches, the part

length is 6 inches and the quantity to produce is 5. After the first

part is produced, the operator is required to raise the knife blades.

Since 24 inches of material is already slit, the remaining four parts

are produced with the knife blades in the up position.

-No to allow the user to proceed to the next job with the knife blades in

the down position.

Note: To increase productivity, additional jobs can be programmed while the

machine is running previously programmed jobs.

MP450S Operator Manual

Automatic Operation

The MP450S runs all programmed jobs automatically.

•To start the machine after all desired jobs have been programmed, press

[Run] .

•To stop the machine at any time, press [Halt] .

The machine halts automatically when all programmed jobs are completed.

Note: If the encoder is counting in the negative direction, change the encoder

direction in the Setup Screen as described previously.

Length Calibration

Note: Calibration is typically required only during machine startup, although

changing coil stock may sometimes require a calibration as well.

Length calibration adjusts for errors in the size and tracking of the measuring

wheel and is expressed as a percentage, with 100% being no correction.

Increasing the correction factor causes the parts to become longer and decreasing

the value shrinks the parts.

The MP450S controller’s length calibration feature automatically computes a

new correction factor. Length Calibration should be used any time part lengths

are incorrect in a consistent manner (e.g., all parts 1mm too long, etc.).

Note: When calculating the correction factor, make several parts (6 to 10)

and use the average of these parts for the part length. The first part produced

should not be used in this calculation since it may be inaccurate due to shear

reaction, boosts motion, or other variances.

To calibrate the MP450S controller,

1. With the controller powered on, press [Calibration] . The display

prompts you to enter a calibration length.

2. When the prompt “Enter Length for Calibration” displays, enter a part length.

Note: The longer a part length you enter, the more accurate the

calibration will be. The minimum length that can be programmed
