Da.8 Command speed

Set the command speed for positioning.

(1) If the set command speed exceeds " Pr.8 Speed limit value", positioning will

be carried out at the speed limit value.

(2) 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 Section 15.2 "List of errors" for details on the errors.)
