Set the input signals and parameters as indicated below.
Item Used device/parameter Description
Automatic operation mode Automatic/manual selection (RYn6) Turn RYn6 ON.
Remote register-based position/speed
setting Position/speed specifying system selection
(RY(n+2)A)
Turn RY(n+2)A ON.
Command system Parameter No.PA03
0 : Absolute value command
system is selected.
Remote register-based position/speed
specifying system selection
Parameter No.PC30
2 : Remote register-based
position/speed specifying system is
selected.
Position command data under 16 bit
(RWwn+4)
Position data
Position command data upper 16 bit
(RWwn+5)
Set the under 16 bits of position data
to RWwn+4, and the upper 16 bits to
RWwn+5.
Setting range: 999999 to 999999
Servo motor speed Speed command data (RWwn+6) Set the servo motor speed.
