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 feedrate table for a feedrate. The feedrate

in this table corresponding to the single digit then becomes the active

feedrate. For more details on single--digit feedrate F--words, refer to

chapter 18.

If you are using a dual--processing system, single--digit feedrate values

operate differently. Refer to page 30-5 for details.

Important: Feedrates must always be entered into the single--digit feedrate

table in units of inches per minute (IPM) or millimeters per minute

(MMPM), depending on the current active feedrate mode (G70/71).

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

steps:

1.

Press the

{SYSTEM SUPORT}

softkey.

2.

Press the

{PROGRAM PARAM}

softkey.

mode.
