7-1 Outline
Position control is carried out by setting positions, speeds, and acceleration/
deceleration times each time in the operating data area specified by the com-
mon parameters.
The positions and speeds set in the operating data area by the MOVL instruc-
tion are output to the Position Control Unit (PCU) automatically at I/O refresh
time. Data transfer is not required.
Start is executed by the ABSOLUTE MOVEMENT command (for the X axis:
word n, bit 03) allocated to the operating memory area (in the CIO Area) or
when the RELATIVE MOVEMENT command (for the X axis: word n, bit 04) is
turned ON.
• The ABSOLUTE MOVEMENT command determines the position from the
absolute position in relation to the origin. With the ABSOLUTE MOVE-
MENT command, a present position unknown error (error code 5040) will
be generated if the origin has not been established.
• With the RELATIVE MOVEMENT command, position control is based on
the amount of relative movement from the present position. Relative
