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:

(softkey level 1)

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

softkey level 1.

(softkey level 1)

FRONT PANEL

ERROR MESAGE

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.

2.2 The MTB Panel

Figure 2.4 shows the MTB panel. Table 2.B lists the selections on this panel. Your system may contain optional or custom MTB panels different than the one shown below. See the documentation prepared by your system installer for details.

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.
