This function is used to limit the command speed to the speed limit value when the
command speed in control exceeds the "speed limit value".
The relation between the speed limit function and each control is shown below.
1-axis linear control
2 to 4-axes linear
interpolation control
(1) Speed clamp
The each axis speed is limited with the speed limit value. When the axis speed
exceeds the speed limit value set in the each axis, the axis speed is cramped
with the speed limit value.
A "warning code 11001" will occur by executing the speed cramp. (However, a
warning will occur at positioning start. It will not occur when the speed reached
the speed limit value.)
