3.7.3 Modifying an Additional Workpiece Coordinate System
I Programming
Command format：G10 L20 Pn IP_; modify an additional workpiece coordinate system.
n：1~48
IP_: setting values of axis address and workpiece origin offset distance;
When G09 is executed, IP value is a setting value of corresponding coordinate system;
When G91 is executed, the specified value of setting value +IP of current coordinate system is
a setting value of a new coordinate system.
Corresponding coordinate system’s value of default axis does not change.
When P is defaulted, a coordinate system is not set, which is taken an alarm.
An alarm occurs when the specified P is beyond 0~48;
An alarm occurs when the specified coordinate data is beyond the above range;
When a program is executed and value of current coordinate system is changed, and the
absolute coordinate system is immediately change.
3.8 Polar Coordinate Command (G15, G16)
The coordinate value can be input in polar coordinates (radius and angle).
Format： G9□ G1□ G16； ……Start the polar coordinate mode
G00 IP_ ；
…
G15； ……
Polar coordinate command
Cancel the polar coordinate mode
Command descriptions：G16：Start the polar coordinate command
G15：Cancel the polar coordinate command
G1□：Plane selection of the polar coordinate command (G17, G18 or G19)
G9□：G90 specifies the zero point of the workpiece coordinate system as the origin of the polar
coordinate system, from which a radius is measured.
G91 specifies the current position as the origin of the polar coordinate system, from which a
radius is measured.
IP_：Specify the addresses and values of selected plane for the polar coordinate system.
The first axis: Radius of the polar coordinate
The second axis: Angle of the polar coordinate
Corresponding axis for radius and angle of the polar coordinate on each plane

The polar coordinate commands G15, G16 are G code of No.17
(2) G15 is the initial state when the system power on. Cancel the polar coordinate command after the
program is finished or reset. （parameter N0.528 RSTP=1）
(3) Absolute command or incremental command (G90, G91) can be used in polar coordinate radius
and angle.
(4) when the polar coordinate radius is specified with the negative value, it is taken as the positive to
execute; when the specified angle is positive, the polar coordinate rotates counterclockwise of the 1st axis’s
