1.4 Reading This Manual

To make this manual easier to understand, we included these explanations of terms and symbols:

All explanations, illustrations, and charts presented are based on standard CNC functions. Operationscan differ from the basic information provided in this manual depending on the configuration of

your grinder machine controlled by the CNC. For details, see the manuals prepared and supplied by your system installer.

You can purchase some of the softkey functions and features as options on the 9/Series control. This manual assumes you have all of the optional features.

Explanations and illustrations assume a 2-axes cylindrical grinder configuration. This means the movement of the grinding wheel on a rotating part or the movement of the grinding wheel on the fixed dresser. Explanations and illustrations were not specifically written for an angled wheel cylindrical grinder though most will apply to the cylindrical grinder configuration.

The control accepts several different alphabetic characters for expressing numerically controlled axes. This manual uses Z and X for the first and second axes on the basic coordinate system. The integrand name for these axes is K and I respectively . Cylindrical angled wheel grinders should also assume Z (real) and X (virtual) axes for the first and second axis on the basic coordinate system with W (real) however, being the actual physical wheel axis.

The term AMP is an abbreviation for Adjustable Machine Parameters. These parameters are used to match the control to a specific machine. AMP configuration is usually done by your system installer.

Program examples are given as radius values. Assume the control is in radius programming mode unless stated otherwise.

Names between the [ ] symbols are keys Names between the { } symbols are softkeys Names between the < > symbols are switches and buttons

found on the operator panel.

found below the CRT.

found on the

standard MTB panel. The term PAL is an abbreviation for Programmable Application Logic.

This is a ladder logic program that processes signals between the CNC and the grinder. It is usually programmed by your system installer.

Operating the Control

2.1.2 Softkeys

You access the various software features and functions of the control through softkeys. Softkeys are the row of 7 keys located at the bottom of the CRT as shown in Figure 2.3. They let you move through the control’s software. The control displays the function of each softkey on the CRT directly above the softkey. In this manual, softkey names appear between the { } symbols.

Figure 2.3 Softkey and Softkey Name Locations

9/Series

Softkeys

11978-I

In this manual, we often describe softkeys as being on a certain level, e.g., softkey level 3. We use the level of the softkey to determine the location or necessary path to reach that particular softkey. For example, to get to a softkey on level 3, you must press a specific softkey on level 1, followed by a specific softkey on level 2. For a listing of all of the softkeys and their respective levels, see appendix A.

Softkey level 1 is the initial softkey level the control displays at power-up. Softkey level 1 always remains the same, and all other levels are referenced from softkey level 1.

The softkeys on opposite ends of the softkey row have a specific use that remains standard throughout the different softkey levels. On the left is the exit softkey displayed with the up arrow { continue softkey displayed with the right arrow {

↑}, and on the right is the

→}.

2-5

Chapter 2

Operating the Control

Use the exit softkey {↑} (on the far left) to regress softkey levels. For example, if you are currently on softkey level 3 and you press the exit softkey, the softkeys change to the softkeys previously displayed on softkey level 2. When you press the exit softkey while holding down the

[SHIFT] key, the softkey display returns to softkey level 1 regardless of the

current softkey level. When more than 5 softkey functions are available on the same level, the

control activates the continue {

→} softkey at the far right of the softkey

area. When you press the continue softkey, the softkey functions change to the next set of softkeys available on that level.

Important: When the number of softkey functions on that level does not exceed 5, the continue softkey is not available.

For example:

When you reach softkey level 1, the above set of softkeys appears. Press the continue softkey {

PASSWORD

SWITCH LANG

On softkey level 1, the control does not display the exit softkey since the softkeys are already on softkey level 1.

We explain the softkey functions for level 1 and 2 in appendix A, and level 3 or higher in the sections that apply to their specific operations.

To use a softkey function, press the plain, unmarked button directly below the description of the softkey function.

You can purchase some of the softkey functions as optional features. This manual assumes that you purchased all available optional features for your machine. If you did not purchase an option, the softkey is blank.

Some features accessed through a softkey can be password protected. When a feature is password protected, the softkey that accesses that feature is no longer displayed.

We show selection names on the MTB panel between the < > symbols when referred to in this manual. Most selections on the MTB panel are configured by your system installer’s PAL program. This manual assumes that PAL has been written as intended for normal operation. If a selection does not work the way it is described i n this manual, see documentation preparedby your system installer.

2.3 SoftwareMTB Panel {FRONT PANEL}

The 9/Series control offers a software MTB panel that performs many of the functions of an MTB panel. This feature uses softkeys instead of the normal switches and buttons of a panel. If your control uses a standard MTB panel (described on page 2-8) or some other custom MTB panel, the requests for operations from the panel take priority. This means that requests from the software MTB panel are ignored if a request from a standard or custom MTB panel is sent.

The software MTB panel’s operation depends on PAL, especially if the control uses either a standard or custom MTB panel. See the documentation prepared by your system installer for details about using the software MTB panel. Your system installer uses PALto disable the

{FRONT PANEL} softkey.

2.6 Emergency Stop Operations

Press the red <EMERGENCY STOP> button on the MTB panel (or any other E-Stop switches installed on your machine)to stop operations regardlessof the condition of the control and the machine.

ATTENTION: To avoid damage to equipment or hazard to personnel, your system installer should connect the

button so that pressing the button opens the circuit

If equipped with the standard MTB panel, the following occurs automaticallyafterpressing the

<EMERGENCY STOP> button:

the control displays “E-STOP” in the message area. This indicates that the control is i n the emergencystop state

the red light in the <CYCLE STOP> button lights up to indicate that the control is in the feedhold state

power to all axis drive motors is turned off

Important: If you press the

<EMERGENCY STOP> button while a part

program is running, program execution can be resumed at the point of interruption. See the mid-program start feature described in chapter 7.

After the control has entered the emergency stop state, you must perform an E-Stop reset before program execution can continue.

ATTENTION: Before resetting the emergency stop state, first locate and eliminate the cause of the emergency stop.

<EMERGENCY STOP> button is locked in the pressed position, it must

2-22

Chapter 2

Operating the Control

To reset the emergency stop state, press the <E-STOP RESET> button. Once you push the E--Stop Reset button to clear the E--S top state, the message, “RESETTING E--STOP”displays to alert you that the control is attempting to come out of E--Stop. After the cause of the E--Stop is resolved, the control clears the “E--STOP”message. If the error condition is not cleared, the “RESETTING E--STOP” message clears, but the “E--STOP”message continues to flash as the control remains in E--Stop state.

If the E-Stop occurred during program execution, the control resets the program when you perform an E-Stop reset (provided AMP is configured to perform a control reset or E-Stop reset). Assuming that you perform a control reset, program execution begins from the 1st block of the program when you press

<CYCLE START>. If the current axis position prohibits this,

the operator can manually jog the axes clear, or consider executing a mid-program start (see page 7-13). If you do not perform a control reset or E-Stop reset, the control aborts the remainder of the program block being executed when E-Stop took place, and a

<CYCLE START> begins program

execution at the next block.

2.7 Access Control

Important: If you do not eliminate the cause of the E-Stop, the circuit connected to the E-STOP STATUS terminals on the sub-basic board remains open, and the emergencystop state is not reset even when you press the

<E-STOP RESET> button.

Reciprocationstops when an emergency stop condition occurs. No motion occurs when the emergencystop is reset. If your control’s AMP is configured such that the control is not

reset after an E-Stop reset, then typically reciprocation resumes with the next cycle start. This allows part programs to be resumed immediately without having to first restart reciprocation. For details, see the documentation prepared by your system installer.

Access control lets your system installer assign different functions of the control to different users by means of a password. See page 2-28 for a list of the functions that can be protected on the control.

Each protectable function is assigned an access level that is made active when the operator enters his password. When an access level is made active, all functions that are assigned to that access level become available. Access levels range between 1 and 8 where 1 is the highest level and 8 is the lowest. A different password is assigned to each of the different access levels. You can assign a total of 8 passwords.

Important: If you do not want to use password protection, select all functions as accessible for access level 8. Since access level 8 is automatically available at power-up, no password is necessary to access any of the functions of the control. You can also disable password

protection by assigning a level as the power-uplevel using the “POWER-UP LEVEL” parameter as described on page 2-29.

2.7.1 Assigning Access Levels and Passwords

This section shows you how to:

set the functions assigned to a particular access level change the functions assigned to a particular access level change the password used to activate that access level

Important: You can only assign functions or passwords to another access level if:

The user attempting to make the change has a higher access level than the access level he is attempting to change. This means that if a user’s password is assigned to access level 6, that user can change only the functions or passwords for access levels 7 and 8. Functions, or a password, cannot be assigned to access level 6 with a level 6 password

Functions that are not available to the current user cannot be assigned to other levels. If a user with access level 6 is changing a lower-access level’s functions, access level 6 must have access to any functions that are changed. For example, if an access level 6 user does not have access to or remove

This section describes the functions on the control that can be protected from an operator by the use of a password. If a user has access to a function, the parameter associated with that function appears in reverse video on the access control screen (see Figure 2.5).

You control access to the functions in Table 2.C by using passwords. Table 2.C describes the function that is enabled (the operator can perform them) if the parameter name appears in reverse video. If the function does not appear in reverse video, the function is protected and cannot be accessed by the operator.

2.10 Displaying System and MachineMessages

The control has two screens dedicated to displaying messages. The MESSAGE ACTIVE screen displays up to nine of the most current system messages and ten of the most current machine (logic generated) messages at a time. The MESSAGE LOG screen displays a log of up to 99 system messages and a separate log of up to 99 machine messages that occurredsince the last time memory was cleared. For single process controls, this log displays up to 11 pages of messages (99 messages total) and up to six pages per process for dual process systems.

Important: The control automatically displays the highest priority, single, active message on all screens (other than the message screen) on line 1 of the CRT. If more than one message occurs with the same priority, the control displays the most recent message (provided no other message is active with a higher priority).

Use the MESSAGE ACTIVE screen to display all the messages that are currently active, or the MESSAGE LOG screen to display a log of the recorded messages. To access these message screens, follow these steps:

The input cursor is the cursor located on line 2 and 3 of the screen. It appears when you must input data using the operator panel (as needed in MDI mode, for example). This section describes how to move the cursor and edit data on the input line by using the keys on the operator panel.

Moving The Input Cursor

To move the cursor left or right in the input area, press and hold the

[SHIFT] key while pressing the left or right cursor keys.

Tomove the cursor between line 2 and 3, use the left or right cursor keys while holding the

[SHIFT] key. The up and down cursor keys

cannot be used. The input cursor wraps around when it reaches the end of the line.

InsertingCharacters

To insert characters into existing data on the input lines, move the cursor as described above. Place the cursor just to the right of the location to insert data. Any data typed in using the operator panel is inserted to the left of the cursor.

DeletingCharacters

To delete characters on the input lines, move the cursor to the right of the character to delete. Press the

[DEL] key to delete the character to

the left of the cursor in the input line.

Deleting All Characterson The Input Line

2.12 {REFORM MEMORY}

Sometimes you must perform a reform memory operation on the control to clear memory. Typically, you do this when:

the amount of RAM memory that can be used by PAL is changed in AMP

a new PAL program has been sent to the control (downloading PAL does not always make it necessary to format)

battery power was lost when the 9/240 control was turned off after 5 days’ backup by the supercapacitor, the optional lithium battery

takes over; this provides 2 years of continuous, accumulated backup for the standard 9/260 or 9/290 control, and 1 year for the 9/260 or 9/290 with extended program storage

Important: You must format any time the control displays the error message“MEMORY CRASH -- REFORMAT.”

You can also perform this operation if you want to delete all part programs in control memory.

After you perform a format operation, it is not necessary to re-installAMP or PAL.

ATTENTION: The reform memory function erases all part programs that are stored in control memory. This includes programs in both the main and protected program directories. You can back up these programs to ODS or to another peripheral device before reformatting as described in chapter 6 and 9.

To reformat control memory and delete all programs stored in memory, follow these steps:

Use the axis detach feature to remove (detach) a rotary table or other axis attachment from a machine. When activated, t he control ignores messages, e.g., servo errors, that occur resulting from the loss of feedback from a detached axis.

Important: The axis detach feature removes the selected axis from the control as an active axis. Any attempt to move the detached axis results in an error. This means that part programs that use the detached axis name cannot be executed. Jog moves and MDI commands that attempt to move the detached axis also result in an error.

You enable this feature in AMP. You must select the axis as “detached”to be considered removed. See the documentation supplied by your system installer for the steps involved in detaching an axis or physically removing axis hardware from your machine.

the expression appears on the input line.

How to Enter Values and Do MathematicalOperations

Mathematical expressions entered on the input line cannot exceed 25 characters. These expressions must contain the numeric or special mathematical operation characters as described below. If you enter any characters that are not numeric or operation characters, the error message “INVALID CHARACTER” appears.

Chapter 2

When programming these functions, place the value that the function is to be performed on in brackets, e.g., SIN [10]. The arc tangent function (ATAN) is the exception. The format for ATAN requires the division of two values, e.g., ATAN [10]/[2] is used to calculate the arc tangent of 5.

Chapter 2

Operating the Control

The control executes functions in Table2.F from left to right in a program block. These functions are executed before the control executes any mathematicaloperators such as addition or subtraction. This order of execution can be changed only by enclosing operations in brackets [ ]. Operations enclosed in brackets are executed first.

Example 2.2 Format for [CALC]Functions

Important: Take precautions when performing calculations within the brackets [ ] following a mathematical function. The control performs operations within the bracket first, and then the mathematicalfunction is performed on this resultant.

For example:

Ifyourmathematical function is: Thenthe resultis:

Operating the Control

Paramacro Variables in CALC Operations

Any paramacro variable can be accessed through the CALC function. Include a # sign followed by the paramacro variable number. When the calculation is performed the value of that paramacro variable is substituted into the equation. You can not change the value of paramacro variables with the CALC function. Local parameters are only available for the currently active nesting l evel of the control (main program, or one of four nested macro programs). You can not perform calculations that contain any paramacro variables if the control is currently executing a program block. The control must be in either cycle stop state, or E-Stop.

Wheel length offsets let the programmerwrite a part program with respect to the same fixed point on the grinder regardless of the wheel being used. This fixed point (called the gauge point) is determined by your system installer. For the purpose of documentation, this manual assumes that the gauge point is a fixed point on the centerline of the grinding wheel. See your system installer’s documentation for details on the location of the gauge point on your system.

This section describes how to enter the length values that are called later when the corresponding length offset is activated. Typically wheel length offsets are activated with a T word as described in chapter 13.

The control stores wheel length offsets in a table called the wheel geometry table. This table stores wheel length offset values under offset numbers. When you select a certain wheel offset number with a T word in the part program, the control references this table and looks up the associated length offset values stored for that offset number. For details on how and when the length offset is activated, see chapter 13.

Resolution of wheel radius and length offset data is determined by the programming resolution selected for the axis in AMP. For example, an X axis that can be programmed with 4 decimal place accuracy also allows 4 decimal place accuracy in the offset tables.

Figure 3.1 illustrates typical cylindrical grinder length offsets. Length offsets for a surface grinder application can be more complex as additional axes can be offset.

Wheel Length Offset Numbers

Call out wheel offset numbers in a program through use of the T word. The last two digits of the T word specify an offset number for wheel length. This number is independent of the dresser/wheel radius and orientation offset number which is the first two digits of T word. The control then accesses the values assigned to that offset number in the wheel length offset table. Length offsets are activated as described in chapter 13.

You can store valid wheel lengths for each axis by using offset numbers ranging from 01 to 32. You cannot use offset number “00” to store wheel offset data but you can program “00” to cancel wheel length offsets. You can call different offset numbers from the wheel geometry and wheel radius table using the same T word.

Chapter 3

Offset Tables and Setup

Important: The first 4 wheel offset numbers (01-04) are reserved for use in conjunction with an in-process dresser. When the in-process dresser is disabled, the control automatically updates these first 4 offsetnumbers with the current grinding wheel size. These offset values should not be manually entered. See chapter 21 for details on using the in-process dressing feature.

AssigningWheel Length Offset Values

Use the wheel length offset to compensate for the wheel position as mounted on the machine. By using the wheel length offset along with wheel radius and orientation information, a programmer can write a part program without concern for wheel dimensions and shape. Measure wheel length values for each axis to define the control point for programming relative to the wheel gauge point (see Figure 3.2). The same wheel can have several offset numbers to let the programmer select which part of the wheel is being controlled.

You can configure each axis on your system to have wheel length offset values. This manual assumes a two axis Z and X configuration.

Chapter 3

Offset Tables and Setup

Figure 3.2 shows typical length offsets for a cylindrical grinder. Generally grinders are configured such that axes move in the negative direction as they move the wheel towards the workpiece (along -X axis) and towards the chuck (along -Z axis). Assuming this applies to your system, enter a positive Z offset value t o offset the gauge point away from the part spindle. Enter a positive X offset value to offset the gauge point away from the part spindle center line. Different wheel control points are established by the values entered in the length offset table.

Cylindrical grinders can have axes assigned in AMP as diameter axes. This allows values to be entered into the length offset table for that axis as either diameter or radius values. This manual assumes that you use radius values. If you enter values as diameters, you must enter the wheel diameter instead of the wheel radius for the axis configured as the diameter axis. G07 and G08 (radius and diameter modes) have no affect on values entered into the offset tables.

3.2 Dresser/Wheel Radius Offsets {RADIUS TABLE}

Enter your length offset data in the wheel geometry table as described on page 3-11.

If you are entering offset values for an angled-wheel grinder you should also read the angled-wheel tool offset section on page 14-16.

Radius offset values let t he programmer write a part program without having to calculate wheel positions relative to the radius of the grinding wheel, grinding wheel corner, or edge of the diamond point dresser. This section describes entering these radius values that are used for dresser/wheel radius compensation as described in chapter 15.

The control stores wheel radius offsets in a table called the radius table. This table stores the radius values under radius offset numbers. Call out a radius offset number with a T word in the part program. The control references this table and looks up the associated radius values. For details on how and when the radius offset is activated, see chapter 15.

The first two digits of the T word specify an offset number for radius and orientation. This number is independent of the wheel length offset number which is the last two digits of T word. Length offsets are activated as described in chapter 13.

3-4

The control supports 3 dresser/wheel radius compensation schemes:

Dresser radius

Corner radius

Entire wheel radius

Chapter 3

Offset Tables and Setup

The dresser radius and corner radius compensation schemes use the same radius table to store a radius value. The entire wheel radius scheme stores the entire wheel radius in paramacro variable #5508. Which dresser/wheel radius compensation scheme to use on your system depends on the current application of your grinder. See chapter 15 for details on how to properly implement these schemes.

Dresser Radius

The control can compensate for errors resulting from slight or even large rounding of the dresser tip. To do so, the radius of the dresser must be entered in the radius table. For more information on activating an offset for dresser/wheel radius compensation, see chapter 15.

CornerRadius

The control can compensate for error resulting from the rounded corner commonly dressed into the grinding wheel. This corner radius should be the corner of the wheel selected as the control point using wheel length offsets.

In order for dresser/wheel radius compensation to properly compensate for wheel corner roundness, you must enter the corner radius of the control point wheel corner into the offset table. The same wheel can have 1, 2, or more corners entered for its corner radius. It is the programmer’s responsibility to use the correct radius (called by first two digits in T word) for the correct control point of the grinding wheel (called by second two digits in T word).

The control can compensate for the radius of the entire grinding wheel. To do so, the radius of the wheel must be entered in the radius table for dresser/wheelradius compensation. This method of compensation does not require any X-length offset to be activated. Only a Z-length offset needs to be activated with the X offset being compensated for by the wheel radius. For more information on activating an offset for dresser/wheel radius compensation, see chapter 15.

Important: An additional radius offset number (33) is available only to the in-process dresser feature. This radius value is the entire wheel radius and changes as the wheel radius diminishes each time it is dressed. See chapter 21 for details on the in-process dresser feature.

To assign a value to radius offset number 33, use either:

3.3 Dresser/Wheel Orientation {RADIUS TABLE}

11987-I

Orientation of the grinding wheel or diamond point dresser is essential information for dresser/wheel radius compensation to function properly. Orientation data tells the control which side of the dresser/wheel is available for grinding relative to the wheel/part surface.

The control uses orientation data during dresser/wheel radius compensation as described in chapter 15. This section describes entering this orientation data. Since orientation data is essential to radius compensation, the orientation data in entered in the radius table. This table also contains information on the dresser/wheel radius as described on page 3-4. Each radius value entered in the radius table requires corresponding orientation data.

When you use PAL to modify the dresser/wheel radius offset table, dresser/wheel radius compensation (G41 or G42) should not

be active. If dresser/wheel radius compensation is active, be aware that the new offset is not placed in part program set-up buffers that have already been read into control memory. This results in the offset not being activated until several program blocks after the current block. The number of setup buffers depends on the number of block retrace steps configured in AMP and what software features are currently being used.

The method described here requires that the offset data be manually measured and then directly keyed into the table.

3.5 Set Offset Data Using {MEASURE}

The measure feature offers an easy method of establishing wheel length offsets. This feature is not available for generating any radius offset data. The control, not the operator, computes the wheel length offsets, and enters these values in the wheel geometry offset table. You can only perform the measure operation on one axis at a time.

Toenter wheel length offsets using measure, follow these steps:

1. Establisha fixed machine position. This position can be any fixed, non-movable location on the machine that the wheel can be jogged against consistently. Determine the value of this location at the gauge point with no wheel offsets active.

Important: No wheel offsets should be active. The value of this position at the gauge point, located in the work coordinate system, must be recorded.

You key in this value in steps 6 and 7.

2. Access the wheel geometry offset table {WHEEL GEOMET}.

3. Cursor down to the offset that you want to change. You can select to

display the offset in either inch or metric measurements.

4. Using incremental, continuous or handwheel mode, jog the wheel surface to be measured against the fixed location determined in step 1 on the axis being measured.

5. Press the {MEASURE} softkey.

6. Keyin the coordinate value of the fixed location determined in step 1.

This coordinate value must be in the same units as the control is currently operating in. For example, you cannot key in an inch value when the control is in metric mode (G71).

If the same length offset must be transferred to other axes, they must be keyed in manually. If the offset must be copied from offset number to offset number, you can use the {COPY OFFSET} feature.

7. Press the [TRANSMIT] key.

The control now subtracts the keyed in location from the current wheel position and enters this differenceas the length offset value in the table.

3.6 Changing the Active Dresser/WheelOffset {ACTIVE OFFSET}

This feature allows the manual activation of wheel length and radius/orientationoffsetswithout the need to program the correct T word to call the corresponding offset number.

Typically you change the wheel length and radius/orientation offsets by programming a T word as described in chapter 13. Use this feature only when you need to activate one of these offset numbers manually.

Important: The control must be in cycle stop or E-STOP state before an attempt is made to change the active offset using this method.

Adjusting this value, for example, allows for use of the same work coordinate systems and programs after a different part or dresser/wheel mounting fixture has been installed on the machine. You can also use t his to offset all work coordinate systems when part programs are transferred from different machines with different mechanical features. See page 11-10 for details on the external offset.

3.8 BackingUp Offset Tables

The control can back up all the information entered in the offset tables and the work coordinate system tables. The control can generatea program consisting of G10 blocks to save these tables. These G10 blocks can contain offset and work coordinate values. Any time this program is run, the set of values contained in these G10 blocks replace the current values in the offset tables.

You can save the G10 program in either control memoryor to a peripheral device. We recommend using both to insure this data is not lost.

This feature is very useful if you use the same wheel or coordinate system offsets on different machines. The same offset tables can be easily set up by running this G10 program on other machines. Also, if written to a peripheral device, you can use this program as a safety backup in case of memory failure.

Important: Once the control begins executing a G10 program that has been previously generated, it clears any data that already exists in the offset table being updated by that G10 command. This makes it impossible for a G10 block to simply add a few offset values. A G10 program must load the entire offset table each time it is run. Wheel geometry, radius offset, and work coordinate tables are separate. Loading data in to one does not clear the others.

5. Whenyou press the {TO FILE} softkey, the control prompts you for a program name. Enter a program name by using the alphanumeric keys on the operator panel and press the [TRANSMIT] key (see page 10-8 on program names).

If you press {TO PORT A} or {TO PORT B} instead of {TO FILE} the control sends the backup program to the device connected to the peripheral port.

3.9 Programmable Zone Table

The programmable zone table feature provides a means to prevent wheel motion from entering or exiting a designated area. For details on programmable zones, see page 11-34.

This table contains the values for programmable zones 2 and 3. These values define the boundaries for the programmable zones and are referenced from the machine coordinate system.

Important: These values can also be entered in AMP by your system installer. You can also modify programmable zone 3 table values by programming a G22 command. See page 11-40 for details.

To display or alter the values in the programmable zone table, follow these steps:

1. Press the {SYSTEM SUPORT} softkey.

3.10 Single-Digit Feedrate Table

Use this feature to change the values set for the single-digit feedrates. When a single-digit F word is encountered during block execution, the control looks to the single-digit feedratetable for a feedrate. The feedrate in this table corresponding to the single-digit F word then becomes the active feedrate. For details on single-digit F words, see page 12-61.

To display or alter the values in the single-digit feedrate table, follow these steps:
