POINT
• The speed can be changed only during standby point positioning, point selection positioning,
address indirect specification positioning, continuous positioning (1), continuous positioning (2),
teaching/teaching playback and fixed-feed/fixed-feed stepping operation.
• The command speed only for Axis 1 is changed. The interpolation speed for standby point
positioning and address indirect specification positioning is the composite speed based on the
command speed for Axis 1 after the speed is changed.
• The speed cannot be changed while decelerating.
