(1)When a regular tool command is specified, the CNC performs
positioning at an angle of 0° on the C–axis. Then, the CNC sets
the CPEN signal to 0.
(2)When the CPEN signal is set to 0, the machine detaches the C–axis
from tool holder.
(3)Once the C–axis is detached, the PMC sets the CFDC signal to 1.
When the CFDC signal is set to 1, the CNC cancels the C–axis
offset, and performs reference position return.
(4)Then, a T code and TF signal are output, after which tool indexing
is performed.
(5)The PMC returns the TFIN signal to the CNC upon the completion
of tool change.
CAUTION
1 When using this function, set bit 2 (MAI) of parameter No.
16360 to 1 and bit 3 (MAB) of parameter No. 16360 to 1.
2 When using this function, enable movement along the T
axis (by setting bit 5 (CRM) of parameter No. 16362 to 0)
only when the tool is at the reference position on the C–axis.
