G90G03: 2-axis counterclockwise absolute position arc interpolation
◆
Overview
This instruction is used to output the set counterclockwise arc interpolation path at the set
combined output frequency. The action is based on the absolute position.

count
Absolute value of the target position on the y-axis (Y1)
S3
X center
coordinate
Difference of the pulse output count of the center
coordinate relative to that in the current position at the x-axis
(Y0), or the pulse count of the radius (R)
S4
Y center
coordinate
Difference of the pulse output count of the center
coordinate relative to that of the current position at the y-axis
(Y1). If S3 indicates R, S4 must be 0x7FFF FFFF.

Functions and actions
This instruction is used to output pulses at the specied frequency and in the specied direction through
the specied port; perform 2-axis counterclockwise arc interpolation; and drive the servo actuator to move
to the specied target position according to the counterclockwise arc interpolation. This instruction is
applicable only to the PLC of the transistor output type. Wherein:
S1 indicates the specied destination (absolute position) of the x-axis. The range is –2,147,483,648 to
+2,147,483,647. The "-" indicates the reverse direction.
