(9) [Da.8] Command speed
Set the command speed for positioning.
• If the set command speed exceeds "[Pr.8] Speed limit value", positioning will be carried out at the speed limit
value.
• If "-1" is set for the command speed, the current speed (speed set for previous positioning data No.) will be
used for positioning control. Use the current speed for uniform speed control, etc. If "-1" is set for continuing
positioning data, and the speed is changed, the following speed will also change. (Note that when starting
positioning, if the "-1" speed is set for the positioning data that carries out positioning control first, the error
"No command speed" (error code: 503) will occur, and the positioning will not start. Refer to

Page 650,
Section 15.5 for details on the errors.
