11. OPTION RELATED TO SPINDLE

When the positional deviation becomes equal to or less than the
number or pulses set with a parameter (orientation completion
signal level [parameter No. 4075 for FS16]), the spindle orientation
completion signal (ORARA) is output.
3) When an orientation operation is started from a speed lower than the
lower orientation speed limit
ORCMA (orientation command)
ORARA (orientation completion signal)
Motor speed
If a spindle orientation command (ORCMA) is entered when the
speed is lower than the lower orientation speed limit (calculated
internally by software), a one–rotation signal is detected (only for
the first orientation after power–on).
The speed is increased according to the motor deceleration time
constant set with parameter No. 4320 to No. 4323 (FS16).
The speed is reduced according to the motor deceleration time
constant set with parameters No. 4320 to No. 4323 (FS16).
When the speed becomes equal to or less than a value calculated
internally by software, the position loop is controlled according to
the orientation–time position gain set with parameters No. 4060 to
No. 4063 (FS16).
When the positional deviation becomes equal to or less than the
number or pulses set with a parameter (parameter No. 4075 for
FS16) for specifying an orientation completion signal level, the
spindle orientation completion signal (ORARA) is output.
