- Relationship between simple spindle synchronous control and spindle
synchronous control
The spindle synchronous control mode and the simple spindle
synchronous control mode cannot be selected for the same spindle at
the same time.
In a mode other than spindle synchronous control mode, no restriction
is imposed on the selection timing of simple spindle synchronous
control. Usually, select simple spindle synchronous control when the
master spindle is not executing a move command in the spindle
rotation control mode or in the Cs contouring control mode.
No restriction is imposed on the timing of simple spindle synchronous
control cancellation. Usually, cancel simple spindle synchronous
control when no command is executed in any spindle control mode.
When simple spindle synchronous control is canceled, the mode of the
slave spindle switches to the spindle rotation control mode. The
master spindle maintains the selected spindle control mode.
The table below indicates the spindle control mode switching of the
master and slave spindles based on the transitions of the simple
spindle synchronous control signal and spindle synchronous control
signal.
Spindle control mode
switching
Switching when the simple spindle synchronous control signal makes a transition from 0 to
1 in each spindle control mode selection state
Master spindle
SP → SP(ESY) CT → CT(ESY)
SV → SV(ESY)
Note 3
SY → SY
Note 4
Slave spindle
SP → SP(ESY)
Note 1
SP → CT(ESY)
Note 2
SP → SV(ESY)
Note 3
SY
→ SY
Note 4
Spindle control mode
switching
Switching when the simple spindle synchronous control signal makes a transition from 0 to
1 in each simple spindle control mode selection state
Master spindle
SP(ESY) → SP CT(ESY) → CT SV(ESY) → SV
Slave spindle
SP(ESY) → SP CT(ESY) → SP SV(ESY) → SP
Spindle control mode
switching
Switching when the spindle synchronous control signal makes a transition from 0 to 1 in
each simple spindle control mode selection state
Master spindle
SP(ESY) → SP(ESY)
Note 4
CT(ESY) → CT(ESY)
Note 4
SV(ESY) → SV(ESY)
Note 4
Slave spindle
SP(ESY) → SP(ESY)
Note 4
CT(ESY) → CT(ESY)
Note 4
SV(ESY) → SV(ESY)
Note 4
The symbols used in the tables above have the following meanings:
SP : Spindle rotation control mode
CT : Cs contour control mode
SV : Rigid tapping mode or spindle positioning mode
SP(ESY) : Spindle rotation control mode during simple spindle
synchronous control
CT(ESY) : Cs contouring control mode during simple spindle
synchronous control
SV(ESY) : Rigid tapping or spindle positioning mode during
simple spindle synchronous control
SY : Spindle synchronous control mode
