Detailed description
2.1 Path feedrate F
Basic logic functions: Feeds (V1)
12 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Linear feedrate (G94)
The linear feedrate is programmed in the following units relative to a linear or rotary axis:
• [mm/min, degrees/min] on standard metric systems
• [inch/min, degrees/min] on standard imperial systems
Revolutional feedrate (G95)
The revolutional feedrate is programmed in the following units relative to a master spindle:
• [mm/rev] on standard metric systems
• [inch/rev] on standard imperial systems
• [degrees/rev] on a rotary axis
The path velocity is calculated from the actual speed of the spindle according to the following
formula:
9 Q)
V: Path velocity
n: Master spindle speed
Where
F: Programmed revolutional feedrate
Note
The programmed F value is deleted when the system switches between the feedrate types
G93, G94 and G95 .
In JOG mode, the response of the axis/spindle also depends on the setting data:
SD41100 $SN_JOG_REV_IS_ACTIVE (revolutional feed rate for JOG active)
• If this setting data is active, an axis/spindle is always moved with revolutional feedrate
machine data:
MD32050 $MA_JOG_REV_VELO (revolutional feedrate with JOG)
or
MD32040 $MA_JOG_REV_VELO_RAPID
(revolutional feedrate with JOG with rapid traverse overlay)
depending on the master spindle.
• If the setting data is not active, then the axis/spindle responds as a function of the setting
date:
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE
(revolutional feedrate for position axes/ spindles).
