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.
