428
If a spindle orientation command (ORCMA) is entered when the
speed is higher than the upper orientation speed limit set with
parameter No. 4038 (FS16), the speed is reduced to the upper
orientation speed limit.
A one–rotation signal is detected (only for the first orientation after
power–on).
The speed is reduced according to the motor deceleration time
constant set with parameter 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 parameter No. 4060 to
No. 4063 (FS16).
When the positional deviation becomes equal to or less than the
number or pulses set with parameter No. 4075 (FS16) for
specifying an orientation completion signal level, the spindle
orientation completion signal (ORARA) is output.
2) When orientation operation is started from a speed between the lower
orientation speed limit and higher orientation speed limit
ORCMA (orientation command)
ORARA (orientation completion signal)
Motor speed
If a spindle orientation command (ORCMA) is entered when the
speed is between the upper orientation speed limit set with
parameter No. 4038 (FS16) and 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 reduced according to the motor deceleration time
constant set with parameter 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 parameter No. 4060 to
No. 4063 (FS16).
