Detailed Description
2.5 Programming
2.5.6 External programming (PLC, HMI)
SD43300 and SD42600
The revolutional feedrate behaviour can be selected externally via the axial setting data:
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE (Rotational feedrate for spindles)
in JOG operating mode using the channel-specific setting data
SD42600 $SC_JOG_FEED_PER_REV_SOURCE (Revolutional fedrate control in JOG
mode)
.
The following settings can be made via the setting data:
>0:
-1:
0:
FPRAON (S2)
Revolutional feedrate for spindle S2 ON, derived from the master spindle
FPRAON (S2, A)
Revolutional feedrate for spindle S2 ON, derived from axis A.
The revolutional feedrate value must be specified with FA[Sn].
FPRAOF (S2)
Revolutional feedrate for spindle S2 OFF.
SPI(n)
It is also possible to program SPI(n) instead of SPI(Sn).
84
The machine axis number of the rotary axis/spindle from which the revolutional feedrate
shall be derived.
The revolutional feedrate is derived from the master spindle of the channel in which the
axis/spindle is active in each case.
Function is deselected.
