6 POSITIONING CONTROL
[Program]
(3) Set the command speed with the vector speed for 2 axes circular interpolation
axis.
(4) The command speed unit is specified in the parameter block.
(5) Set the number of pitches within the range of 0 to 999. If it is set outside the
setting range, the servo program setting error (error code: 28) occurs and
operation does not start.
(6) All of the circular interpolation axis, linear axis end point relative address,
command speed, radius (2 word data above) and number of pitches (1 word data)
are set indirectly by the word devices.
