In "speed control" ("[Da.2] Control method" = Forward run: speed 1 to 4, Reverse run: speed 1 to 4), control is carried out in
the axis direction in which the positioning data has been set by continuously outputting pulses for the speed set in "[Da.8]
Command speed" until the input of a stop command.
The eight types of speed control includes "Forward run: speed 1 to 4" in which the control starts in the forward run direction,
and "Reverse run: speed 1 to 4" in which the control starts in the reverse run direction.
Refer to the following for the combination of the reference axis and the interpolation axis.
Page 64 Interpolation control
The following charts show the operation timing for 1-axis speed control with axis 1 and 2-axis speed control with axis 2 when
the axis 1 is set as the reference axis.
The "in speed control" flag ([Md.31] Status: b0) is turned ON during speed control.
The "Positioning complete signal" is not turned ON.
