Refer to Section 5.3 "List of positioning data" for information on the setting details.
POINT
Set a value in "
Da.8
Command speed" so that the speed of each axis does not
exceed the "
Pr.8
Speed limit value". (The speed limit does not function for the
speed calculated by the QD75MH during interpolation control.)
