3 Equipment Description

3.1 Robot and Controller

3 Equipment Description

This chapter contains brief descriptions of The Miller

Auto-Axcess DI/E

Digital welding system components.

3.1 Robot and Controller

The robot controller coordinates the operation of the various welding system components. The controller executes instruction sequences provided in a robot job file. As the controller steps through the series of instructions, it directs the movement of the torch, and operates the welding power supply. The robot moves the welding torch and supply lines through a series of programmed steps. The controller sets the speed, direction, and position of the robot as it moves from point to point. It communicates weld signals through a digital interface board mounted in the controller cabinet. The controller sends command values for wire feed speed, voltage/arc length, arcon and arcoff. The robot also selects one of eight weld programs by setting three outputs. The Auto-Axcess DI/E

Digital power source communicates to the controller when the arc is established, when there is a fault condition, or when the wire is stuck to the puddle. The power source also communicates the fault type back to the DX100.

This enhanced interface also features a pendant application which allows weld data to be assigned to the eight weld programs. It also provides functionality similar to Millers’ File Manager Software.

3.2 Auto-Axcess DI/E Digital Power Supply

The Auto-Axcess DI/E Digital power source is a three-phase, highfrequency, multi-process inverter welder. The welder operates at either 50 or 60 Hz frequency and 190 to 630 volts AC or DC.

Auto-Line

™

automatically adjusts to line voltage, so no external adjustments are necessary. The power source has multi-process MIG capability consisting of standard MIG (GMAW), standard pulse MIG

(GMAW-P), Accu-Pulse (GMAW-P), Accu-Speed (GMAW-P),

Accu-Curve (GMAW-P), as well as a RMD (GMAW-SC) mode. (RMD is a paid option on the DI welders and is standard on the Axcess E Digital welders)

Accu-Pulse reduces burn through problems, increases welding travel speeds, and is superior to pulse mode when welding with short arc lengths. For even shorter arc lengths on steel Accu-Speed is available.

Accur-Curve has a softer pulse that can be used on aluminum. The optional RMD (Regulated Metal Deposition) process is a short circuit transfer process in which the power source alters the welding current to improve the droplet transfer while minimizing spatter levels. It is limited to use at wire speeds below 250 ipm (depending on electrode diameter) on thin gauge steel applications.

The Auto-Axcess DI uses a DeviceNet interface and is compatible with the

DX100 controller.

The Auto-Axcess E Digital has the ability to use either a DeviceNet or

EtherNetIP interface. The DeviceNet interface (on the E Digital machine) provides the same interface functionality and control as the Auto-Axcess

DI/E Digital. The EtherNetIP implementation of the Axcess E Digital provides additional robot control for process monitoring control.

The Auto-Axcess DI/E Digital comes standard with many programs for carbon steel, aluminum, and stainless welding, including Accu-Pulse, standard or adaptive pulse, Accu-Speed, Accu-Curce, conventional MIG, and RMD (included free-of charge on Auto-Axcess E Digital machines.)

The standard Yaskawa interface provides an array of functionality including allowing the user to customize the arc starting and ending timing.

3.4 Miller AA-40G Wire Feeder

The AA -40G Wire Feeder is an open frame-type wire feeder equipped with four (4) geared (0.045 in.) feed rolls as standard. The feeder is rated at 650 amps 100 percent duty cycle and weighs 7.5 kg. The wire feed speed range is 50-1400 ipm, with a default maximum of 999 ipm. If a wire feed speed greater than 1000 ipm is necessary, the data in the welder condition file must be reset.

3.5 Miller-Motoman Pendant Interface (HMI) Software

This Interface Software connects the DX100 Controller to each of the welding units (up to 4) that are part of the system. The HMI software allows the operator to set the Auto-Axcess DI/E Digital parameters from the DX100 programming pendant.

This software is standard with the Auto-Axcess/DX100 system.

NOTE

These functions are controlled by the Auto-Axcess DI/E

Digital. Pre-Flow, Run-in WFS, and Start power begin with an Arcon command. Crater Fill, Retract and Post flow start when the Arcoff command is issued. Yaskawa Motoman recommends the welding sequencing be done in AcrStart

Files to ensure timing is coordinated with the robot motion.

3. Run-in WFS:

Select the welder (if more than one is connected to the system) and program number to view or change.

Only that program will be affected.

In the event of an EtherNet IP interface, the

"Inductance / Arc Control" is set by the "Miller-Prog-

Sel" macro job.

When using a MIG program the desired Inductance is between 0 - 99.

When using a Pulse, Accupulse, or RMD program set the Arc Control valve between 0 - 50.

This parameter sets the wire feed speed (WFS) during arc initiation. The wire feeds at the run-in speed when the arcon command is issued until an arc is established. Generally, the run-in speed is set lower than the WFS for the actual weld. This helps the arc start better. Once the arc is established, the

WFS changes to the set value.

Sets the shielding gas pre-flow time. If enabled, the gas will come on for the specified length of time before the wire will start to feed. This will add cycle time at the Arc Start. There is a purge output, which can be turned on in the robot job file that does not add this extra time.

This function retracts the wire at the end of the weld.

A time in seconds and a WFS must be specified.

Typical settings are 100 ipm and 0.3 seconds. This helps create separation between the wire and weld puddle for large fillets.

This function is used to modify the default start sequence. When enabled, the specified Volts/ Arc

Adjust and WFS parameters are used for the time indicated during the start of the weld, then changed to those in the Job program. When the Ramp function is disabled, the WFS and Volts/Arc Adjust remain constant during the Start Power time. When Enabled, the WFS and Volts/Arc Adjust begin at the specified values and time, then ramp up to the Job values over the time set in the ramp box. Robot motion starts once the arc is initiated unless timers are inserted.

Continues the gas flow for the set amount of time after the arc ending sequence.

If a crater fill is desired at the end of the weld, enable the function and set a time, Volts/Arc Adjust and

WFS. The Ramp function will slope the WFS and

Volts/Arc. Adjust up or down to the crater fill parameters over the time specified. Use the Hyper

Start function to set Welder Control if the robot is to wait for the welder crater fill.

This button must be pushed to activate and save any changes. If the screen is left without saving, the changes will be lost. Save Disabled indicates the operator does not have rights to make changes to the screen.

Error Preferences

The Miller Auto-Axcess DI/E Digital has several errors that can be enabled

or disabled depending on user preferences (). Sometimes these errors will

give “nuisance” trips, causing excessive downtime. If the actual error will not cause any safety issues or equipment damage, it can be turned off.

When the errors are disabled, they will be ignored by the Auto-Axcess DI/

E Digital and no error message will be sent to the robot controller.

These errors are global within the Auto-Axcess DI/E Digital. They affect all eight weld programs.

The Yaskawa/Miller interface includes a mapping of Miller error codes into the DX100 controller. Welder errors will generate a user alarm on the robot with the error message displayed. Welder alarm history can be

viewed under user alarms (see chapter 5.4 “Troubleshooting” at

page 5-6). The error code is recorded along with the date, time, program,

and step number of the error.

Auto-Axcess DI/E Digital

4 Theory of Operation

The Auto-Axcess is a Gas Metal Arc Welding (GMAW) power supply capable of non-pulsed, or MIG, and pulsed

(GMAW-P) modes of operation.

The DX100 utilizes a DeviceNet interface to the Auto-Axcess. This interface provides two basic levels of controls:

• Real time display of weld data.

• Programming of welder set-up data from the teach pendant.

Operators will not be aware of any programming difference between

Digital or Analog interfaces with the

Auto-Axcess

. Both interfaces function with the INFORM weld instructions utilized on the DX100 controller. The digital interface uses an application created by Motoman called the Miller HMI. This provides pendant screens with dialog boxes to allow Managers or Operators (if allowed by Managers) to make changes to programs in the welder.

The weld settings and sequence of operation are controlled by the robot.

Traditionally, the current and voltage settings were communicated to the welder as a proportion of a 0-14 volt analog signal. The weld contactor, arc establish input, and error signals were discrete inputs and outputs.

These basic signals were interfaced between the XEW01 board in the controller to the Auto-Axcess with a cable that had about a dozen wires.

These commands and signals are set and sequenced through the controller’s concurrent I/O (CIO) program. This program has a system section which can not be edited by Users because of Safety functionality.

The User section is provided for users to add fixture and cell control logic.

INFORM functions such as RETRY and ANTI-STICK use signals in the ladder to operate. Motoman developed the HyperStart function to allow users to set values used in the system section to optimize cycle time and arc alarm conditions to suit the application.

The standard Auto-Axcess interface addresses the welding input and output signals to the physical I/O points on the XEW01 board. Weld settings, current and voltage, are entered in the robot program as an

INFORM command or Arc Start File. These settings (i.e. 200 amps, 18.0 volts) are converted to a proportional analog value by referencing the

Welder Condition File. The Welder Condition File is a table of 8 settings that allows the robot to be scaled to different wire types and power supplies. In the case of the Auto-Axcess, the Welder Condition File is scaled to be 0-999 ipm wire feed speed (instead of amperage) and 0-50.0 volts.

When the

Auto-Axcess

is in a pulse mode, then the voltage value is 3/4 of the arc adjust setting (i.e. arc voltage setting of 22.5 provides an arc adjust setting of 45 on the welder). The arc adjust setting on the

Auto-

Axcess

has a setting of 0-100 with a nominal setting of 50. The welder is synergic which means an arc adjust value of 50 will provide good welding conditions through the whole range of wire feed settings. Users may want to reduce the arc adjust setting to get a shorter arc length to suit a given application.

166465-1CD

Auto-Axcess DI/E Digital

4 Theory of Operation

4.1 Miller HMI

The

Auto-Axcess

has 8 program locations for different process settings.

The process can be changed between welds or even during welding by setting I/O commands in the robot program to select a different program.

There are 3 outputs from the robot to the welder for selecting schedules.

These outputs should be labeled in the output display and programming instructions are provided in this manual.

The

Auto-Axcess

functions in exactly the same manor, but signals are addressed to a DeviceNet board inside the DX100. The settings in the

Welder Condition file are still necessary to convert the INFORM settings to a 16 bit Mregister in the CIO. AutoCal is not necessary (and is not available) on the

Auto-Axcess

because the digital data is communicated as exact numbers.

WARNING

Do not exchange Welder Condition Files (WELDER.DAT) or concurrent

I/O programs (CIO.LST) between robots that have analog and digital interfaces. These files are different and will cause improper operation.

Arc Start Files and Arc End Files can be transferred between robots regardless of digital or analog interface.

4.1 Miller HMI

The key feature of the

Auto-Axcess

is the ability to perform set-up functions from the DX100 pendant. This is performed with a Motoman pendant application called the Miller HMI. When this button is pushed on the pendant, it starts an application which takes over the pendant display.

This application provides much of the functionality of the Miller File

Manager software used with a Palm PDA. The

Auto-Axcess

retains the

User Interface display. This allows users to change processes from the welder or confirm weld settings on the LED meter display.

Most of the pendant application is used for set-up functions. Most of the functionality is only available in TEACH mode to ensure signals are not passed while the power source is welding. There is Management password protection to allow administrators to determine if they want to allow operators access to change program information in the power source. They can initiate edit lock on the welder to keep operators from being able to make program changes from the welders.

NOTE

The pendant application allows users to set functions for start power and crater fill in the power source. Motoman recommends that these functions be set in arc start files or enhanced arc start files. The settings in the welder are not synchronized with robot motion and adverse welding conditions could be created.

Auto-Axcess DI/E Digital

4 Theory of Operation

4.2 Pulse Mode

The

Auto-Axcess

functions as a Master on the DeviceNet network. The robot is a slave and other devices should not be connected to this network, unless they are for monitoring purposes. The digital interface utilizes a total of 9 bytes and would have been addressed by Motoman for your exact cell configuration. Users should make back up copies of their

I/O settings including the concurrent I/O (CIO.LST). The pendant HMI application also allows the settings made on the HMI to be saved to flash memory. This backup is only saving the selections made from the pendant and is not saving the welders memory. It is recommended that Users invest in the File Manager software from Miller to support maintenance functions (this is true whether Digital or Analog versions are in use).

With the

Auto-Axcess

, Motoman is able to log error messages from the welder. These can be viewed on the message display when the alarm occurs. The error messages are logged in the robot’s alarm history in the

User Alarm section. The alarm is saved with date, time, job name, and step number when the alarm occurred.

4.2 Pulse Mode

Pulse Mode behaves identically to non-pulsed (MIG) mode except that spray current, (low/no-spatter) can be achieved for virtually the entire range of wire feed speeds. Spray transfer is accomplished by elevating the current above that required for globular transfer, holding the current while a droplet(s) is formed and detached from the electrode, and then dropping the current to a low background level. The amount of time at this background level is often based (inversely proportional) on the wire feed speed - higher wire feed speeds require more droplets per second and so shorter background times (higher frequencies) are often used. Pulse mode is recommended for welding conditions (wire feed speeds) wherein globular transfer would be achieved in non-pulsed mode. Pulse mode is typically used for all wire feeds speeds for aluminium GMA welding.

Voltage to 23.5

In MIG mode, the voltage value is the actual reference value desired.

Example:

Voltage required is 21.8 volts

In the Arc Start File (ASF) and/ or Arc End File (AEF) set

Voltage to 21.8

CURRENT: The Current setting is actually Wire Feed Speed in inches per minute. A setting of 300 will give 300 ipm of wire.

BURN BACK: The Miller Auto-Axcess DI has a Sharp Start routine to reduce wire ball size. Do not set high voltage or low wire feed speed setting in the Arc End files, this can create adverse results.

RETRY: If RETRY is used (ON), set the Voltage and Current in the Arc

Auxiliary Condition File to the same values as in the Arc Start Files.

5.1.3

Arc End Files

CURRENT and VOLTAGE: Arc End Files are used if a crater fill is required at the end of the weld sequence. If no crater fill is required, a simple

ARCOF command can be used. If it is desired to use the Arc End files, but no crater fill is needed, set the CURRENT and VOLTAGE to the same values as used in the corresponding Arc Start File, and set the ROBOT

PAUSE TIME to 0.0 sec.

BURN BACK: The Miller Auto-Axcess DI has a Sharp Start routine to reduce wire ball size. Do not set high voltage or low wire feed speed settings in the Arc End files, this can create adverse results.

ANTI-STICK: The Miller Auto-Axcess DI has a built-in anti-stick feature, so in general this function is not needed and should be set to OFF.

5.1 Set-Up Overview

5.1.5

Selecting Weld Programs

Eight separate weld programs can be defined for the Miller Auto-Axcess

DI. Each program can be configured for weld mode (MIG, Pulse,

AccuPulse, Accu-Speed, Accu-Curve, RMD), wire type (Steel, Aluminium, etc.), diameter, and shield gas type. The programs can be selected by the

robot using three outputs, as shown in Section 5.2.1 Weld Program

Selection. These outputs are assigned by Motoman, and cannot be

changed. Check the Motoman system prints to verify which outputs are used, since they can vary depending on the controller configuration.

Fig. 5-13: Universal Output Screen

The output status can be viewed by pressing the IN/OUT buttons then

selecting Universal Outputs (see Fig. 5-13). The page key will index

between different groups (8 bits). In this example, the Miller schedule select bits are labeled:

• OUT#0045 #10064

• OUT#0046 #10065

R1 PROGRAM 0

R1 PROGRAM 1

• OUT#0047 #10066 R1 PROGRAM 2

Table 5-3 "Universal Outputs" shows the values necessary to select weld

programs 1-8 using Universal Outputs 45, 46, and 47 which are

OGH#(12). The outputs may change depending on the system configuration.

5.2 Robot Job Programming

5.2.1

Weld Program Selection

The robot selects one of the eight weld programs by setting three outputs.

Typically a binary value (0-7), referenced by a DOUT instruction, is programmed into the robot job. This binary value of 0-7 corresponds to programs 1-8 in the Miller Auto-Axcess DI.

In this example, the schedule select bits have been connected to

Universal Outputs 45, 46, and 47. These three bits comprise the first three bits of Output Group Half (OGH) #12.

Sample Robot Job:

0000 NOP

0001 MOVJ VJ=33.0

0002 DOUT OGH#(12)5

(Welding start position)

(Selection of Schedule #6)

0003 ARCON AC=285 AV=22.0

(ArcOn request)

0004 MOVL

0005 ARCOF

0006 MOVJ VJ=33.0

The above job selects Program #6 with the DOUT instruction. It also sets wire feed speed to 285 in./min and sets either voltage to 22.0V (MIG mode) or trim to 44% (Pulse or AccuPulse) depending on the mode selected in Program #6.

5.3 Welder Front Panel Display

When the welder is powered on, “MOTO” will appear on the welder display. During normal operation, the welder display shows the following:

• Power Supply Idle (not welding): Displays the set Wire Feed Speed and Voltage or Arc Length values.

• Power Supply Welding: Displays the actual average Amperage (or the wire feed speed) and actual average Voltage.

• Immediately after Welding: Displays the actual average Amperage and actual average Voltage for five seconds.

5.4 Troubleshooting

The Miller Auto-Axcess generates several error messages that are displayed on the front panel (see the Miller Auto-Axcess Manual for a complete list). Some of the more common errors are displayed and logged as User Alarms on the DX100 programming pendant. The less common errors are logged on the pendant as an Unknown Error, and the Miller

Auto-Axcess must be checked to determine the exact error. For other service related problems, call Yaskawa Motoman Customer Service (937)

847-3200.

The following is a list of User Alarms and messages displayed for welder

#1 on the programming pendant. These messages will repeat for welders

#2, #3, #4.

2. If this message only displays on the welder, check the Devicenet connection between the power source and the controller.

Check the E-Stop connection on the Miller

Auto-Axcess. It must be cleared before the unit will operate.

The welder did not receive a tach signal from the wire feeder. Check the cable and connection between the wire feeder and welder.

6.1 Setting Proportional Speed Instruction

6 Miller Auto-Axcess E Digital

The Miller Auto-Axcess welder combines the Miller Auto-Axcess welder with a powerful and feature packed process monitoring tool called

"CenterPoint". "CenterPoint" is a PC application which is used to set-up weld processes and limits. These welding sequences and limts are then transferred to the welder where they reside during production (PC application can be disconnected/removed). During production the sequence and limits are monitored on a weld-to-weld and part-to-part basis to ensure that production parts stay within the predefined limits and sequence.

6.1 Setting Proportional Speed Instruction

With the AutoAxcess E Digital (EtherNetIP interface) the robot needs to transmit its TCP travel speed to the Auto-Axcess so that the power source can calculate the heat-input of the weld. This is accomplished by issuing a command contained in a pre-existing job. The "R*-SET-PROPORTIONAL-

SPD" instruction set's an analog channel with a value pertaining the robot's actual speed while executing a linear, circular, or spline move. The scaling for the value is set by issuing a "ARATION" instruction. Each robot's job sets a predefined analog output register which is then rescaled in robot's CIO ladder program before being transmitted to the welder.

Below are the jobs and the instructions that set the proper scaling.

6.1.1

The "R*-SET-PROPORTIONAL-SPD.JBI"

Only needs to be set once and should be called either in the start-up portion of the "Master" job or within the main weld job. It does not need to be shut-off of adjusted once it has been set.

NOTE

The "V=50" is setting the velocity to voltage ratio. The value of 50 is in cm/min. If another unit of travel speed is selected under the "SETUP" menu then the units may need to be entered so that they correlate/equal 50cm/min.

• R1-SET-PROPORTIONAL-SPD.JBI ' ARATION A0#(36) BV=1.00

6.2 MACRO Job Settings

The Auto-Axcess EtherNetIP interface allows the robot to communicate the welder letting it know where the robot physically is within the welding sequence. The robot can also instruct the welder what the "Part ID" and

"Weld ID" is for each weld. The robot is also able to indicate the start and end of a part which then calculates the complete part processing time. To do this, the following macro jobs are used and described detail.

The macro job instructions can be located on the pendant under the

"Macro" button.

6.2.1

MILLER-PROG-SEL Macro

Use this macro routine to specify the weld program at the start of a weld or change the weld program mid-weld. It also allows adjustment of the arc characteristics for the specified program. These characteristics can be changed either at the beginning or mid-weld if desired

• Welder Number: Allows specification of the desired welder.

Allowable values are 1 to 4.

• Program Number: Allows specification of program number. The number entered specifies which of the eight programs in the welder to execute. Allowable values are 1 to 8 (a value of 0 will allow weld settings to be specified from the front-panel of the welder)

• Inductance/Ctrl: Depending on the welding process selected this control has different meanings and acceptable ranges:

– MIG: In MIG processes this controls the welder's "Inductance" setting where the range is 0-99. The default inductance is a value of

30.

– Synergic (pulse): In synergic mode this controls the welder's

"Arc Control" setting. The range is 1-50 with a default value of 25.

• Slope:

– MIG: In MIG processes this contols the welder's "Slope" setting where the range is 1-99. The default slope setting is a value of 50.

– Synergic (pulse): In synergic mode this control has no impact

6.2.2

MILLER-STRT-PART Macro

Use this macro to signal the start of a new part. It starts the cycle timers within the welder and allows identification of the "Part ID" that's going to be welded. It also allows specification "Weld ID" which tells the welder what weld is being made next allowing out of sequence part processing.

The last two settings allow the enabling or disabling of various weld errors.

• Welder Number: Allows specification of the desired welder.

Allowable values are 1 to 4.

• Part ID: Identifies the "Part ID" of the upcoming part. The "Part ID" specified must be configured within the CenterPoint application with the appropriate number of welds and limits before being able to process the part and receive valid data regarding the result of the part following processing.

• Weld ID: The "Weld ID" settings allow specification of the upcoming weld. It allows a user to identify the weld before making it. An

"Automatic Increment" function allows setting the "Weld ID" equal to

"0" which will cause the welder to start at "Weld ID" number 1 and automatically increment the count without further intervention.

• Enable Weld Errs: This setting controls how the robot responds to individual welds which are outside of the predetermined acceptable window of operation.

– Enable Weld Errs = 1: will cause the robot to alarm following every weld that is outside of the acceptable limits. This occurs at the end of the weld and will cause an interruption in welding of other robots if they happen to welding at the same time.

– Enable Weld Errs = 0: will cause the robot to continue on its programmed path following the completion of a "bad" weld. There will be no interruption in the processing of the part.

• Enable Part Errs: This setting controls how the robot responds to a

"Part" which is determined to be outside of the predetermined acceptable limits. A part error will be generated if any of the individual welds were outside of their specified limits, if the number of welds did not match the predetermined

– Enable Part Errs = 1: will cause the robot to alarm following the completion of the part during which any of the individual welds or the number of welds did not match the predetermined number of welds specified within initial setup

– Enable Part Errs = 0: will allow the robot to continue without alarming even if the part is flagged with an error.

Weld Error Reporting

Weld Error Reporting: Based on the "Enable Weld Errs" made in the

"MILLER-PART-START" macro. The power source can alarm at the completion of a weld and trigger a robot-based user alarm notifying the user of the weld fault. The robot will present the user with a detailed explanation of what welding parameter was outside of limits. The robot's system job builds a "Dynamic" alarm based on what parameters the welder detects being out of limit. The system job build-up this alarm and presents it to the operator and logs the alarm in the alarm history. Below are the possible contents of the "dynamic" alarm:

• ALARM 8*99: Wld Err:*"

– V+ Welding voltage over limit

–

V- Welding voltage below limit

A+ Welding current over limit

– A- Welding current below limit

– G+ Gas flow over limit (requires gas flow sensor and sensor board within welder)

–

– G- Gas flow below limit (requires gas flow sensor and sensor board within welder)

W+ Wirefeed speed over limit

W- Wirefeed speed below limit

D+ Weld duration (time) over limit

D- Weld duration (time) below limit

Part Error Reporting

Based on the "Enable Part Errs" setting made in the "MILLER-PART-

START" macro, the robot can stop production with an user alarm if one of the welds or the part processing chracteristics is outside of the predefined limits. Part errors are presented at the completion of a part which is specified with the "MILLER-END-PART" instruction being issues in the job. Once the "MILLER-END-PART" instruction is executed for the particular welder, the robot's system job builds a "dynamic" alarm based on what parameters the welder detects as being out of limit. The system job build-up this alarm and presents it to the operator and logs the alarm in the alarm history. Below are the possible contents of the "dynamic" alarm:

• ALARM 8*98: Part Err:*

– Missed Wld(s): Indicates that the part just completed had one or more missing welds

– Proc Flt(s): Indicates that one or more of the welds in the just completed part had one or more welds outside of the predetermined limits

– Time Flt(s): Indicates that one or more of the time characteristics being monitored by the welder was outside of its acceptable range

– Wld Cnt Flt(s): Indicates that the number of welds completed on the last part did not match the number of expected welds for the part type specified.

– Clamp Time Flt: The amount of part processing time was longer or shorter than the acceptable limit specified within the

"CenterPoint" application.

– Arc Time Flt: The amount of actual arc welding time monitored during the duration of the last part exceeds or is below the allowable limit set within the "CenterPoint" application.
