17. AXES CONTROL
NC FUNCTION
103
The PMC can directly control any given axis, independently of the CNC.
In other words, moving the tool along axes that are not controlled by the
CNC is possible by entering commands, such as those specifying movimg
distance and feedrate, from the PMC. This enables the control of turrets,
pallets, index tables and other peripheral devices using any given axes of
the CNC.
Whether the CNC or PMC controls an axis is determined by the input
signal provided for that particular axis.
The PMC can directly control the following operations :
(1) Rapid traverse with moving distance specified
(2) Cutting feed–feed per minute, with moving distance specified
(3) Cutting feed–feed per revolution, with moving distance specified
(4) Skip–feed per minute, with moving distance specified
(5) Dwell
(6) Continuons feed
(7) Reference position return
(8) 1st reference position return
(9) 2nd reference position return
(10)3rd reference position return
(11) External pulse synchronization–Main spindle
(12)External pulse synchronization–first manual handle
(13)External pulse synchronization–second manual handle
(14)Feedrate control
(15)Auxiliary function
(16)Selection of the machine coordinate system
(17)Torque control command
The PMC is provided with number of axis these operations using input
and output signals.
By issuing commands through two paths (for Power Mate i–D) or eight
paths (for Power Mate i–H), the PMC can simultaneously control
multiple axes separately. Use parameter to determine which path controls
which axis. Commands may be issued through one path to two or more
axes, thus allowing the PMC to control multiple axes using one path.
NOTE
This function can not used for Power Mate i–D (2–path
control).
