6. AC SPINDLES
B–63325EN/03
342
SPINDLE: Indicates the type of a motor each spindle uses.
Serial/analog spindle : Serial/analog spindle: Indicates a serial or analog spindle.
Main motor/submotor : Indicates the motor type (main or sub) that has been se-
lected, if the serial spindle is provided with a two–spindle
changeover function.
High–/low–speed winding : Indicates the winding type (high– or low–speed) that has
been selected, if the motor for the serial spindle is pro-
vided with an output changeover function.
OPERATION: Indicates the status of the spindle.
Speed control : Carried out according to the RIxx DI signal.
Rigid tap
Spindle positioning
Cs contouring : Serial spindle only
Synchronous : Serial spindle only
Orientation : Serial spindle only
GEAR: Indicates the state of the gear selection signal.
Serial Spindle : Indicates the state of CTH1s and CTH2s. First to fourth
stages.
Analog Spindle : Indicates the state of GR1s, GR2s, and GR4s. First to
eight stages.
The parameters that can be displayed and updated vary with the items,
such as operation, main motor/submotor, high–/low–speed winding, and
gear selection. The monitored spindle data varies with the operation
mode and motor type.
