5.4.4 Processing for exceeding speed limit for each axis
Processing is different concerning exceeding speed limit for each axis depending on the setting for excessive
speed processing (parameter No.0261).
(1) Using a speed clamp
When parameter No.0261 is set to 0, if there is an axis that exceeds the speed limit, other axes grouped
with the axis are also clamped.
The actual acceleration time is the time until the feed speed after clamping is reached.

(2) For using alarm stop (example for continuous operation point change)
When parameter No.0261 is set to 1, if there is an axis that exceeds the speed limit for point toggling other
than start up or continuous operation, an alarm is set and start up can not be performed.
During continuous operation, if there is an axis that exceeds the speed limit, an alarm is set and
deceleration to a stop is performed.
