(d) S-analog high-speed tapping function (option)

By structuring the position loop in the NC side and synchronizing with the servo axis, tap

cutting is carried out without using floating tap chuck. Setting the S-analog high-speed tapping

input to the general-purpose input and adding the speed command voltage to the S-analog

input section realize this function.

(e) 1-drive unit 2-motor changeover function

One spindle drive unit rotates two motors that are not used simultaneously. The motor drive

wire is changed over with contactor, and signal wire with FR-TK to select which one to use.

When two motors must be rotated simultaneously, this function cannot be used.

(f) Coil changeover function

This function is used when using the coil changeover motor to gain an extensive constant

output range without a gear. The coil selection signal is set to the general-purpose input, and a

contactor for coil changeover, which is connected with the motor drive wire, is changed over

through a compact relay by turning ON/OFF this signal.

For details on each specification above, refer to MDS-C1-SPA Instruction Manual.
