[Function]
This signal informs that the L coil select function is being executed. This function changes the
spindle motor coil to attain constant output characteristics over a wide range including low speed
ranges.
[Operation]
Turn the "L coil selection" (LRSL) ON after attaining a speed (parameter SP020) at which the
rotation speed can be changed.
When "L coil selection" (LRSL) turns ON and the coil is changed, "In L coil selected" (LRSO) will be
output to the PLC.
(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.
