1) If the positioning speed is set lower than the parameter-defined speed limit
value, the actual acceleration/deceleration time will be relatively short. Thus, set
the maximum positioning speed equal to or only a little lower than the
parameter-defined speed limit value.
2) These settings are valid for OPR, positioning and JOG operations.
3) When the positioning involves interpolation, the acceleration/deceleration time
defined for the reference axis is valid.
