Siemens SINUMERIK 810D

Detailed description
2.2 Metric /inch measuring system
Basic logic functions: Velocities, Setpoint/Actual Value Systems, Closed-Loop Control (G2)
30 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Note
The FGREF factor also works if only rotary axes are programmed in the block.
The normal F value interpretation as degree/min applies in this case only if the radius
reference corresponds to the FGREF default setting, when:
• G71/G710:
FGREF[A]=57.296
• G70/G700:
FGREF[A]=57.296/25.4
Example:
The following example illustrates the effect of FGROUP on the path and the path feedrate.
N100 R1=0
N110 FGROUP(X,A)
N120 G91 G1 G710 F100
; Feedrate=100 mm/min or 100 deg/min
N130 DO $R1=$AC_TIME
N140 X10
; Feedrate=100 mm/min
; Path=10 mm
; R1=6 s approx.
N150 DO $R2=$AC_TIME
N160 X10 A10
; Feedrate=100 mm/min
; Path=14.14 mm
; R2=8 s approx.
N170 DO $R3=$AC_TIME

; Feedrate=100 degrees/min
; Path=10 degrees
; R3=6 s approx.
