Detailed description
2.2 Feedrate FA for positioning axes
Basic logic functions: Feeds (V1)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
31
• NC/PLC interface (channel-specific)
The feedrate is output at the channel-specific NC/PLC interface:
DB21, ... DBB158 - DBB193
For a description of the channel-specific NC/PLC interface signals (modification signal,
machine axis number of positioning axis, etc.) see:
References:
/FB1/Function Manual, Basic Functions; Various Interface Signals and Functions (A2)
• NC/PLC interface (axis-specific)
The feed value is output at the axis-specific NC/PLC interface:
DB31, ... DBB78 - DBB81
Note
Maximum axis velocity
The maximum axis velocity is not exceeded:
MD32000 $MA_MAX_AX_VELO (maximum axis velocity)
F function output to the NC/PLC interface
Output of the F functions to the NC/PLC interface is not recommended. Activating the
output of F functions to the NC/PLC interface can cause a drop in velocity in continuous-
path mode. The output of F functions to the NC/PLC interface can be suppressed:
MD22240 $MC_AUXFU_F_SYNC_TYPE (output time of the F functions)

RESET response
After end of program or NC-RESET, the feedrate value takes effect depending on machine
data:
MD22410 $MC_F_VALUES_ACTIVE_AFTER_RESET = <value>
Value Meaning
0 After NC RESET the default values are effective.
1 After NC RESET the last FA values to be programmed are effective.
