Mitsubishi FX2N-10GM - Cod 02 (CW), Cod 03 (CCW): Circular Interpolation with Center Point Specification

FX Series Positioning Controllers Program format 5
5-23
5.6.3 cod 02 (CW), cod 03 (CCW): Circular interpolation with center point specification
c
CW/CCW
This instruction specifies the travel to the target
position around the center coordinates at the
peripheral speed "f".
When the start point is equivalent to the end point
or when the endpoint coordinates (target coordi-
nates) are not specified, the travel locus makes a
complete circle.
de
X/Y axis target position (x, y)
The target position can be specified by an incre-
mental or absolute address. The units and the set
range are equivalent to those for cod 00 and cod 01.
fg
X/Y axis center coordinates (i, j)
The center coordinate always treated as an incre-
mental address from the start point. The units and
the set range are equivalent to those for cod 00 and
cod 01.
h
Peripheral speed "f"
Set the circular operation speed. The acceleration/deceleration time constant (PARA. 10)
and the units of peripheral speed are equivalent to those for cod01.
Program example
cod90 (ABS); Absolute drive method.

When interpolation instructions are executed consecutively, path operation is performed (Refer
to Section 5.4.2).
