PARAMETERS
FANUC AC SPINDLE MOTOR a series
239
Magnetic flux switching point used for calculating an acceleration/
deceleration time constant used for spindle synchronization control
6300 3480 3336 4336
6480 3700
Data range : 0 to 32767
Standard setting : 0
Set a speed for switching the acceleration/deceleration time constant
used for spindle synchronization control.
In the area below the speed set in this parameter, acceleration/
deceleration is performed according to the time constant set in
parameter No. 4032 (acceleration/deceleration time constant at spindle
synchronization control). In the area above the speed set in this
parameter, the time constant varies with the torque characteristics.
When 0 is set in this parameter, linear acceleration/deceleration is
performed. Set a time constant in parameter No. 4032.
The same value must be specified in this parameter and parameter No.
4032 for the first and second spindles, subject to spindle
synchronization.

6302 3482 3338 4338
6482 3702
Data unit : 1%
Data range : 0 to 1000
Standard setting : 0
Set the velocity loop gain at the maximum speed by specifying a
percentage of the velocity loop gain at the base speed.
When 0 is set in these parameters, the velocity loop gain is constant.
