FUNCTIONS
FANUC AC SPINDLE MOTOR aC series
269
A. Check that normal operation can be performed.
B. Prepare and check the ladder program for spindle synchronization control.
B. (See Section 11.4 in the Descrpitions (B–65162E).)
C. Set the parameters related to spindle synchronization control (See Subsec. 2.2.3).
D. Check the position coder signal and position coder related parameters.
D Position coder signal is used
D Use the motor speed obtained from the position coder signal.
D The relationship of the rotation direction between spindle and spindle motor
D Mouting direction of the position coder
D Gear ration
E. Check the spindle synchronization speed. (Set the common spindle speed to that of the spindle
E. whose maximum rotation speed is lower than that of the other spindle.)
F. Set and check the rotation of direction at the spindle synchronization
control
D Direction of rotation of the spindle motor while spindle synchronization
G. Check the overshoot or hunting do not occur before the spindle achieves the maximum speed.
D Position gain on servo mode
D Acceleration/Deceleration time constant at spindle synchronization control
D Magnetic flux switching point used for calculating an Acc/Dec time constant at spindle synchronization control
D Bell type Acc/Dec time constant at spindle synchronization control
H. Check the error pulse between spindles is within "10p.
D Position gain on servo mode
D Gear ratio and Gear ratio setting resolution
D Motor voltage setting on servo mode
D Velocity loop proportional, integral gain on servo mode
I. Check the operation of the spindle phase synchronization control
D Shift amount at spindle phase synchronization
D Spindle phase synchronization compensation data
J. End the checking of the spindle synchronization operation.
Parameters are underscored. See Section 2.2.3.
