Feed / Speed

To change the feedrate and/or spindle speed for a specific port, click on the port in the port list and select the Feed/Speed tab. The feed/speed tab is shown below. You must have user access rights to change feed and/or speed parameters. If you are not logged on, you will be prompted for the user password (if required).

The following section describes how to adjust the feedrate. The method for adjusting the spindle speed is identical to this.

All controls on this tab are disabled if the server is not licensed for feed/speed adjustment.

Online adjustment of feedrate and spindle speed.

The feedrate is adjusted using the controls inside the Feedrate frame, in the upper half of the dialog.

The feedrate controls are: A slider, three feedrate indicators (In, Out and New), two fields to specify the minimum and maximum feedrates (Min and Max), a checkbox to select absolute adjustment, and an emergency button (red circle with white cross).

In addition to these controls, the Apply button, and the Direct Mode checkbox are shared between the feedrate and spindle speed controls.

param

Feedrate slider

The slider is used to adjust the feedrate.

There are two methods for adjusting the feedrate: Indirect and Direct. With the indirect method, you should select the desired feedrate by moving the feedrate slider, and the press Apply.

With the direct method, you just move the slider, and the feedrate is changed immediately, unless the selected port is configured not to insert feedrate information (Send On Adjustment = Send No Data), in which case, the feedrate is not changed until a new feedrate value is encountered in the input file.

By default, the indirect method is used. To enable direct mode, check the Direct Mode field and press Apply. If you select another port, leave the feed/speed tab, adjust the max/min values or press the emergency button, direct mode will be disabled.

param

Absolute

When this field is checked, the feedrate is adjusted in absolute mode. When using absolute mode, the feedrate is adjusted independent of the feedrate specified in the transmitted file.

When moving the feedrate slider, the feedrate can be adjusted between the minimum and maximum values specified in the Min and Max fields.

If this field is not checked, the feedrate is adjusted in relative mode. In relative mode, the new feedrate is specified as a percentage value of the feedrate specified in the transmitted file.

Moving the slider in relative mode will adjust the feedrate from 0% to 300% of the value specified in the input file, i.e. if the last value encountered in the transmitted file was 1200, the feedrate can be adjusted from 0 to 3600. The resulting value is also checked against the maximum and minimum values specified in the Min and Max fields. I.e. if the minimum value is 500 and the maximum value is 3000, the relative adjustment is limited to 500-3000.

If this field is disabled (grayed) it is because absolute adjustment is disabled for this port. For information on how to enable/disable absolute mode, please refer to the Reference Manual.

param

In

The In field displays the current feedrate with no adjustment, this is the same as the last feedrate value found in the transmitted file. If no feedrate value has been found, this field shows "???", and you can't use relative feedrate adjustment, since there is no value to base the relative change on. If you need to change the feedrate value while the In field shows "???", you have to use absolute adjustment.

param

Out

The Out field displays the current feedrate, this is the same as the last feedrate value sent to the CNC.

If you are using direct mode this field shows the same value as the New field, unless the selected port is configured not to insert feedrate information (Send On Adjustment = Send No Data), in this case the Out field will not change its value to match the New field until a new feedrate value is encountered in the input file.

For further information about the Send On Adjustment setting, please refer to the Reference Manual.

If no feedrate value has been sent to the CNC, this field shows "???".

param

New

The New field displays the result of the selected adjustment.

If the result is not available, this field shows "???".

param

Min

This field shows the minimum allowed feedrate. To change the minimum allowed feedrate, change the value in the Min field and press Apply.

The minimum value must be between the minimum and maximum feedrate specified in the protocol configuration. For further information please refer to the Reference Manual.

param

Max

This field shows the maximum allowed feedrate. To change the maximum allowed feedrate, change the value in the Max field and press Apply.

The maximum value must be between the minimum and maximum feedrate specified in the protocol configuration. For further information please refer to the Reference Manual.

param

Emergency button

The emergency button is used to cancel any changes in feedrate adjustment.

If the selected port is configured not to insert feedrate information (Send On Adjustment = Send No Data), the current feedrate adjustment is not canceled until a new feedrate value is encountered in the input file.

For further information about the Send On Adjustment setting, please refer to the Reference Manual.
