(b) Switching request signal (SPSLA)
[Function] It is used as an instruction signal which selects the spindle motor.
0 : The main spindle motor is selected.
1 : The sub spindle motor is selected.
[Usage] This signal is changed after stopping the spindle motor.
Speed zero signal (SSTA) is used for confirming that a spindle motor is
stopping.
Since it is necessary that motor power is off for spindle changing, please
set off the spindle rotation command (SFRA/SRVA) and the spindle
orientatation command (ORCMA) at switching spindle motors.
(c) Power-line status check signal (MCFNA)
[Function] The selection status signal of the electromagnetic contactor for switching
the spindle motor power-lines is input.
0 : The main spindle is selected.
1 : The sub spindle is selected.
[Usage] Usually, the state of the auxiliary contact (contact A) of the magnetic
contactor for the sub spindle motor is entered directly.
[Function] When bit 2 of parameter No. 4014 (FS16) is set to 0, this signal is used
as the power line state check signal. So, the state of selection by the
magnetic contactor for spindle motor power line switching is entered.
0: The main spindle motor is selected.
1: The sub spindle motor is selected.
[Usage] In the case of changing from the main spindle to the sub spindle, this
signal is set from ”1” to ”0” after confirming that the electromagnetic
contactor on the main spindle side is off and that the electromagnetic
contactor on the sub spindle side is on.
In the case of changing from the sub spindle to the main spindle, this
signal is set from ”0” to ”1” after confirming that the electromagnetic
contactor on the sub spindle side is off and that the electromagnetic
contactor on the main spindle side is on.
