L COIL SELECTION
[Function]
The L coil selection control is a function that obtains constant output characteristics in a wide range
including low speed ranges by changing the spindle motor coils.
[Operation]
Set the rotation speed to a changeable speed (parameter SP020) before turning the "L coil
selection" (LRSL) ON.
When "L coil selection" (LRSL) turns ON, the "In L coil selected" (LRSO) will be notified to the PLC
after the changeover is completed.
During "In L coil selected" ON, the spindle parameters (SP321 to SP384) will be used instead of
(SP257 to SP320).
(Note 1) L coil selection control can be selected when the following parameter is set.
Parameter SP034/bit2 is set to 1.
(Note 2) This signal is valid for a system having a control unit high-speed serially connected with
the spindle controller and a coil changeover specification spindle motor.
As a principle, the built-in type is the target.
