7-3-12 G29: ORIGIN UNDEFINED
Forcibly sets the origin to an undefined state for the specified axes.
Format
G29_<Axis name ... >
Operands
X, Y, Z, and U axes
Description
This command forcibly sets the origin to an undefined state for the specified
axes.
• The No Origin Flag will turn ON in the PLC Interface Area.
• An asterisk (*) will be displayed for axes with undefined origins on the
present value display on the Teaching Box.
The present position will not change with this command, but the present posi-
tion of the machine will be updated continually. The following will occur if the
origin is not defined.
• The software limits will be disabled.
• Zones will be disabled depending on the settings of the system parame-
ters (i.e., they will be disabled when the zones depend on the origin being
established).
• Positioning will not be allowed using G00, G01, G02, G03, G26 and G27
commands (when the axis mode is Normal Feed Mode).
Perform one of the following operations to re-establish the origin.
• Execute ORIGIN SEARCH (G28).
• Execute CHANGE REFERENCE COORDINATE SYSTEM PV (G54).
Programming Example
The following example sets the X and Y axes to an undefined state.

7-3-13 G30: SPEED CONTROL AXIS FEEDING
Performs the feed rate control of a maximum of four axes.
Format
G30_<axis movement command ... >
Operands
The following table shows the possible settings for the operands.
Description
The axis is fed in the positive direction if the coordinate data is set to positive.
The axis is fed in the negative direction if the coordinate data is set to nega-
tive.
The feed rate of each axis can be set individually.
X-axis feed rate = X-axis maximum feed rate x X-axis override value/100
Y-axis feed rate = Y-axis maximum feed rate x Y-axis override value/100
Z-axis feed rate = Z-axis maximum feed rate x Z-axis override value/100
U-axis feed rate = U-axis maximum feed rate x U-axis override value/100
The feed rate is set with the system parameters.
Override value: Set with in PLC Interface Area or Teaching Box within a
range of 0.1% to 100.0%.
Example:
The following X-axis feed rate will be obtained if the X-axis
maximum feed rate is 10,000 mm/s and the X-axis override
value is 50.0%.
X-axis feed rate = 10,000 x 50.0 /100 = 5,000 mm/s.
