10. Spindle orientation
(option)
An orientated
spindle stop can be programmed
via the positioning
loop of the Vth. axis.
This is, for example, important
when using an automatic
toolchanger
or the 3D-Touch
probe system
TS 510 with infra-red transmission.
Feedback is performed
by an incremental
rotary encoder ROD 426 with 1024 Iinies. The maximum
spindle
speed for orientation
is 14 000 rpm.
Nominal value programming
is within
0,5 angular degrees.
Nominal values can be calculated as a PLC-positioning
routine or from an orientation
cycle. Moreover,
positioning
may be made to the reference mark, the absolute value of which, is stored under parameter
MP 240.
Spindle olrientation
can be solved individually
via the PLC-program.
In the PLC-standard
program a
recommended
solution
is provided as of program No. 234 601 03 which can also be varied via machine
parameters.
Spindle orientation
takes place from standstill
in a clockwise rotation.
If the spindle is already rotating,
the rotating direction
last programmed
is valid.
10.1
Malchine parameters for spindle orientation
The positioning
loop of the Vth. axis is activated and optimized
via the following
machine parameters:
The input of the Vth axis is designed for squarewave signals with a frequency
of max. 250 kHz. The
rotary encoder is an ROD 426 with 1024 lines.
Please note:
When usiing the rotary encoder ROD 426, the transducer supervision for axis V is to be switched off.
With spindle orientation
a nominal value minimum
limitation
(specified by machine parameters) is
inactive.
