Detailed description
2.1 Path feedrate F
Basic logic functions: Feeds (V1)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
11
Programming example:
. .. .. G94 ....
Selection of feedrate type (mm/min)
X30 Y20 F200
Path feedrate = 200 mm/s
FL[Z]=50 Z-30
Max. feedrate for Z axis: 50 mm/s
2.1.2 Type of feedrate G93, G94, G95
Effectivity
The feedrate types G93, G94, G95 are active for the G functions of group 1 (except G0) in the
automatic modes.
G94 or G95 can be used for traversing in JOG mode.

Reciprocal feedrate (G93) (applies only to 840D/810D)
The inverse-time feedrate is used when it is easier to program the duration, rather than the
feedrate, for retraction of a block.
The inverse-time feedrate is calculated from the following formula:
Y
) )>PLQ@
V
F: Inverse-time feedrate
v: Required path velocity in mm/min or inch/min
Where
s: Path length in mm/inch
Programming example:
N10 G1 G93X100 Y200 F2
; The programmed path is traversed in 0.5 min.
Note
G93may not be used when G41/G42 is active. If the block length varies greatly from block to
block, a new F value should be programmed in each block for G93.
