2. FUNCTION EXPLANATION
FANUC AC SPINDLE MOTOR a series
65
This parameter specifies the detection level of orientation completion
signal (ORARA) which is a DO signal. If the positional deviation falls
within the specified range, ORARA goes 1.

Orientation stop position shift value
6577 3077 3077 4077
Data unit : "1 pulse
Data range : –4095 to 4095
Standard setting : 0
This parameter specifies a shift value of orientation stop position.
Specifying a positive value shifts the spindle stop position
counterclockwise by the specified number of pulses.

Motor voltage setting on orientation
6584 3084 3084 4084
Data unit : 1%
Data range : 0 to 100
Standard setting : Depends on the motor model.
This parameter specifies the motor voltage in orientation. Usually,
specify 100.

Maximum speed of position coder signal detection
6598 3098 3098 4098
Data unit : 1 min
–1
Data range : 0 to 32767
Standard setting : 0
This parameter specifies the maximum speed at which the position
coder signal is detected. If 0 is set in this parameter, the maximum
motor speed (parameter No. 4020) is assumed.

Data range : 0 to 6400
Standard setting : 0
These parameters specify motor deceleration time constants in
high–speed orientation. If 0 is specified, the high–speed orientation
function is disabled, and the normal orientation function is enabled.
