FANUC AC SPINDLE MOTOR a series
2. FUNCTION EXPLANATION
B–65160E/02
146
Parameter PRM 5820 #0 or #1=”0” Counterclockwise (CCW)
Parameter PRM 5820 #0 or #1=”1” Clockwise (CW)
(8) The gear ratio of the spindle to the position coder can be set only to
one to one.
Identical gear ratios must be set for the 1st and 2nd spindles.
(Parameters 5610 and 5660)
(9) Sequence state in spindle synchronization control

Waits for the signal that indicates
that synchronization speed has
been reached to be generated.
(Synchronization control of spindle
speed is in progress.)
0 0 1 0
Waits for the signal that indicates
that synchronization speed has
been reached to be set.
0 0 1 1
Waits for the signal that indicates
that synchronization control of
spindle speed is completed and
the command for spindle phase
synchronization to be generated.
