1 General
On two serial spindles, it is possible to execute spindle synchronous control by input signal
so that one spindle (slave spindle) follows another spindle (master spindle).
To take an example of using, it is possible to execute rotary guide bush control on two
spindles.
2 Specification
To synchronize these two spindles, electronic gear box function(EGB) of serial spindle is
used. In the Spindle EGB, the synchronous pulse is produced from the feedback
pulse of the position detector attached to the master axis in the motor control, and the slave
axis rotates with the pulse. Feedback pulse from Master side to Slave side is forwarded by
the
communication between spindle amplifiers.
In this functon, PMC input signal is used for Simple spindle EGB mode ON/OFF.
In order to turn on to Simple spindle EGB mode, the slave spindle has to be Cs contouring
control mode, though the master spindle may be any mode.
As for the spindle system configuration (motor, amplifier, sensor), please use the same
system configuration as spindle EGB system. As for the details, please refer to “FANUC AC
SPINDLE MOTOR i series PARAMETER MANUAL (B-65280EN) 5.8 Spindle EGB
(Spindle electronic gear box)”.
