SETUP APPL PARAM SCREEN


SETUP APPL PARAM SCREEN

Applicator parameter setup allows you to change the predefined setup of each application parameter used in your system. A maximum of six applicator parameters can be set up per gun. This setup also allows you to calibrate the parameters that require calibration.

By default, applicator parameters 1-4 are assigned to gun 1, and parameters 7-10 are assigned to gun 2. They are

  • Paint Fluid Flow

  • Atomizing Air

  • Fan Air

  • Electrostatics

    Note

    If you want to define more applicator parameters for your system, you must set up additional internal parameters. Contact FANUC America Corporation for more information.

Other applicator parameters that can be used are:

  • Turbine Air (used with bell applicators)

  • Shaping Air (similar to fan air)

    Caution

    After you set applicator parameters, you must turn off the controller and then turn the controller on again so it can use the new information. If you do not do this, the operation of your system will not reflect the changes you made.

Table 1, " Default Applicator Parameters " describes each default applicator parameters. Table 3, " Applicator Parameter Setup Items " describes the applicator parameter information you must set up.

Table 1. Default Applicator Parameters

Applicator Parameter Description

Paint Fluid Flow

Fan/Shaping Air

and Atomizing Air

This item is the fan/shaping and atomizing air pressures which are stored along with the paint fluid flow rate in the preset table. Separate calibration tables for paint fluid flow, fan and atomizing air are stored on the controller. The calibration table contains 10 atomizing/fan/shaping air pressures in psi or scfm values, and corresponding 10 transducer values each for air pressure. Paint fluid flow must always be the first applicator parameter and it can be calibrated by color.

Electrostatics

This item corresponds to a table of predetermined electrostatic levels. There are the same number of electrostatic presets per color as there are fluid presets.

The equipment selected to provide the electrostatic charge will determine the type of data stored and how it is processed. Typically, the electrostatic value is sent out via an analog output or a digital output.

Typical analog electrostatic values can range from 25 to 100 kilovolts. You are required to enter upper and lower electrostatic limits when the robot is set up. If a zero voltage is required you can enter a value of 0.

Typically, the controller will send out the desired electrostatic value through the digital outputs via discrete bits. The discrete outputs can have three values including off. As the controller reaches a estat instruction, it will search for the specified preset table to determine the specific color and output the proper bit setting.

APPLICATOR PARAMETER DESCRIPTION

Turbine Air

This item controls the speed to the turbine drive for a bell applicator. A typical range for turbine air is 0-60 Krpm.

Note

Except for calibration, the setup items in Table 3, " Applicator Parameter Setup Items " are fixed by the type of hardware in your system and typically should not be changed.

Table 3. Applicator Parameter Setup Items

Item Description

Title

This item is a 16-character user-defined name for the application parameter. By default, four applicator parameters are defined: Paint Fluid Flow, Fan Shaping Air, Atomizing Air, and Electrostatics.

Table Name

This item is a 4-character user-defined name used as a title on the Preset Table screen.

Output Type

This item can be analog, binary, discrete, or direct.

Analog is only used with analog output hardware and must be calibrated.

Binary is used with a group of output bits and allows output of a binary number to external equipment. These outputs can be calibrated (with the help of external equipment), scaled, or not calibrated.

Discrete is used to control individual bits in a group of output bits, for example, a "high bit" and a "select low bit." Discrete does not use calibration.

Direct does not use the preset tables or calibration. The number programmed in the paint instruction is directly output.

Anticipation Time

Units: ms

Range: -9999 to 9999

This item is the amount of time, in milliseconds, that the robot begins to change the specified control output before the robot reaches the programmed position. This time goes with the preset or electrostatics instruction to compensate for any delay from the applicator transducer. A negative value (eg.-100ms) will change the specified control output 100ms before the node that contains the attached preset [] or estat [] instructions.

I/O Setup Complete

Values: YES or NO

This item is for display only and is maintained by PaintTool as the operator enters or changes the items in the SETUP Applicator Parameters screen. It indicates whether a parameter has been set up yet.

Calibration Table

This item displays the status, source, and date and time of the last calibration. The calibration table is accessed using the CAL function key.

Status

This item indicates the current status of the Calibration Table. Status is for display only and is maintained by PaintTool following any changes to the Calibration Table.

Complete means that one of the following operations has been performed successfully: scale, copy, set not required, calibration sequence with all data points filled. The copy function can only be performed on tables in which the status is complete.

Not complete means that one of the following operations has been performed: changing the source to Table By Color, starting a calibration sequence but not testing all the values, or any operation that causes the minimum set up complete for the application parameter controls to be NO.

Not required means that calibration is not necessary.

Source

This item is for setting the source configuration. Valid values are Table by Color, Cal. Table, and Not Required.

Table by Color means there is a separate calibration table for each defined color, and that each color requires calibration.

Cal.Table means there is one calibration table for all colors.

Not required means that calibration is not needed for this parameter.

Date/Time

This item is for display only and is maintained by PaintTool. It indicates the date and time the last operation was made on the calibration table. If any of the following operations are performed, the date/time will be updated: copy, calibration sequence, scaled, set not required, set by color, or a change to specific data points of a calibration sequence.

The date/time will not be changed for the calibration table of an application parameter when the calibration is by color and only a table associated with a specific color is changed.

Calibration Units

This item identifies the units used in the calibration sequence. Typically, calibrated units are psi , or pounds per square inch. The units are user-defined and do not affect the actual calibration.

Rack Number

This item is the physical location on which the output process I/O board or modular I/O is mounted. Your system can contain multiple racks. Process I/O boards are always assigned Rack 0. Modular I/O begins at Rack 1.

Slot Number

This item is the slot space on the rack where the process I/O board or modular I/O is connected.

Output Number

This item is an integer value used to determine the specific hardware port used.

Number of Bits

This item is the number of bits allocated per output. For binary or discrete outputs, you must select a value between 2 and the maximum for the output module.

First Bit or Channel

This item is the location of the first output bit in the output module. It is the starting bit number. Output module bits are considered to be numbered from 1 to 32.

This value does not apply for analog outputs.

Strobe Length (ms)

This item is used only if the output type is binary or direct. The strobe length informs any external equipment of the update. The length of that strobe is adjusted by this parameter.

Strobe Output Number

This item is the digital output number (DOUT) for the strobe signal. The strobe is sent to the cell controller so that it will read the binary or direct signal.

Maximum Command Value

This item is a user-defined real number used for range checking of the command values from the preset tables and application errors. The units are user-define d.

Minimum Command Value

This item is a user-defined real number used for range checking of the command values from the preset tables and application errors. The units are user-define d.

Maximum Control Value

This item is used for range checking of the control output (Analog Output, Group Output and so forth). The units are in output counts.

Minimum Control Value

This item is used for range checking of the control output (Analog Output, Group Output and so forth). The units are in output counts.
