element
Meaning
FUNCTION
S-PULSE
Start of syntax for pulsing spindle speed
P-TIME or
RESET
Define the duration of an oscillation in seconds, or
reset the pulsing spindle speed
SCALE Spindle speed change in %
Only if P-TIME has been selected
FROM-SPEED Lower speed limit from which the pulsing spindle
speed will be effective
Only if P-TIME has been selected
Optional syntax element
TO-SPEED Upper speed limit up to which the pulsing spindle
speed will be effective
Only if P-TIME has been selected
Optional syntax element
Proceed as follows for the definition:
Show the soft-key row with special functions
Press the PROGRAM FUNCTIONS soft key
Press the FUNCTION SPINDLE soft key
Press the SPINDLE-PULSE soft key
Define oscillation period P-TIME
Define speed change SCALE
The control never exceeds a programmed speed limit.
The spindle speed is maintained until the sinusoidal curve
of the S-PULSE FUNCTION falls below the maximum
speed once more.
