COMPLEMENTARY
FUNCTIONS
6.4 COMPLEMENTARY FUNCTIONS
The CNC offers the following complementary functions.
F
Feedrate for the axes
S
Spindle speed.
T
Tool number / Zero offset
M
Miscellaneous (auxiliary) function
This programming order must be maintained within a block; but all of them need not
be programmed in the block.
6.4.1 AXIS FEEDRATE "F"
This function indicates the feedrate of the axes when operating in closed positioning
loop.
When operating in servo-controlled open loop, the path is not controlled.
If "F" is programmed while in non-servo-controlled open loop, the CNC will issue
error 45.
With the "F" function ,it is possible to program the feedrate of the axes for G01, G02
and G03 movements.
In rapid positioning, G00, the feedrates for the axes are set by machine parameters
"P27" and "P67".
If "F" is not programmed or "F0" has been programmed, the CNC carries out the
G01, G02 and G03 interpolations at the feedrates set by machine parameters "P27"
and "P67".
It is possible to vary the feedrate of the axes by means of the external operator panel
"JOG 100" or by using the Feedrate Override inputs, pins 10 and 11 of connector
I/O1.
6.4.2 SPINDLE SPEED "S"
With the "S" function, the spindle speed is programmed directly in revolutions per
minute.
It accepts values between S0 and S9999, corresponding to 0 rpm. and 9999 rpm.
The actual maximum values are limited by machine parameters "P36", "P37", "P38"
and "P39", depending, in each case, upon the selected spindle speed range.
