Second spindle control output signals
(b) Orientation completion signal (ORARA)
D This signal is set to 1 when the spindle stops near a specified position
(within "1_, for example) after an orientation command is entered.
ORARA is set to 1 when the following conditions are satisfied:
– ORCMA = 1
– Speed zero signal = 1
– The spindle stops near a specified position.
The third condition (near a specified position) is set using parameter
No. 4075 (FS16) for orientation completion signal detection level
specification. When all of the three conditions above are satisfied, the
orientation completion signal is output. If the orientation completion
signal is not issued despite sufficient time having elapsed after the
input of an orientation command, an error is assumed. Ensure that
such an error is detected with the power magnetics sequence, and that
an orientation alarm is issued.
D Only after this signal is set to 1, start workpiece attachment or
detachment.
D The orientation completion signal is output when the spindle is within
about "1_ of a specified position. This means that this signal does
not represent a complete stop.
D When the spindle is displaced from a point near a specified position
by an external force, this signal is set to 0.
