Data range : 0 to 32767
Standard setting : Depends on a motor model.
This data is used to set the maximum speed of the spindle motor.
In the ROM version 9D11, the spindle control software estimates the
motor speed from the motor current and has the velocity loop using the
estimated speed.

Data unit : 0.1%
Data range : 0 to 1000
Standard setting : 150
This data is used to set the detecting range of the speed arrival detection
signal (SAR).
When the estimated speed reached the range within " (setting data/10)%
of commanded speed, the bit of the speed arrival detection signal (SAR)
is set to ”1”.

This data is used to set the detecting range of the speed detection signal
(SDT).
When the estimated speed reached (setting data/10)% or less of maximum
speed, the bit of the speed detection signal (SDT) is set to ”1”.
