Feedrate Control and Spindle Motion
7.16 Multiple feedrate values in one block (F.., ST=.., SR=.., FMA.., STA=.., SRA=..)
Fundamentals
Programming Manual, 10.2004 Edition, 6FC5 298-7AB00-0BP1
7-43
Parameters
G25 Lower spindle speed limitation
G26 Upper spindle speed limitation
S S1 S2=…=… Minimum or maximum spindle speed
Range of values Value assignment for the spindle speed can be between
rpm ... 9999 9999.9 rpm.
Caution
A spindle speed limitation programmed with G25 or G26 overwrites the speed limitations in
the setting data and thus remains stored after the end of the program.
Example
N10 G26 S1400 S2=350 S3=600 ;Upper speed limitation for master spindle,
;spindle 2 and spindle 3
7.16 Multiple feedrate values in one block (F.., ST=.., SR=.., FMA.., STA=..,
SRA=..)
Function
The "Several feedrates in one block" function can be used independent of external analog
and/or digital inputs to activate
• Different feedrates of an NC block,
• dwell time, and
• Retraction
in synchronism with the movement.
The HW inputs signals are combined in one input byte, see description in: /FB1/, Description
of Functions, A2, Various Interface Signals.
