I Programming
S: Spindle speed (r/min).
The feedrate value is set by system data parameter No.030 when the power is turned on for the system;
an F value is invariable after the F command is performed. The feedrate is 0 after the F0 is executed. The F
value is invariable when the system is reset or emergency stop.
The feed override is memorized when
the power is turned off.

Data parameter N0.029
：
acceleration/deceleration time constant of cutting feed
；
Data parameter N0.030
：
initial speed of cutting feed’s acceleration/deceleration
；
Data parameter N0.041
：
initial speed in MPG/Step feed mode
；
Data parameter N0.042

Note: The cutting feedrate becomes uneven when the spindle speed is less than 1 rev/min in G95 mode; the actual
feedrate has following error when the spindle speed fluctuates. In order to guarantee the machining quality, it
is recommended that the spindle speed can not be lower than spindle servo or the lowest speed of effective
torque introduced by inverter during machining.
