4 Explanation of Interface Signals
4.1 PLC Input Signals (Bit Type: X***)
Cont. Signal name
A Spindle servo-ON
[Function]
This signal is a signal output from spindle controller (spindle drive) with high-speed serial coupling specifications, and
informs that the spindle is in the position control (synchronous tap control, etc.) state.
[Operation]
The "Spindle servo-ON" signal (SSA) turns ON when the spindle is ready (SMA signal is ON), the servo-ON command has
been transferred from the controller to the spindle controller, and the spindle controller is in the servo-on state.
Note that this signal turns ON during rotation by the "Spindle forward run start" (SRN) or the "Spindle reverse run start"
(SRI) other than during spindle synchronization, and during spindle orientation.
This signal (SSA) turns OFF when the servo-ON command is canceled.
Spindle servo-on command
(*1)
Spindle servo-on (SSA)
(*1) The spindle servo-ON command is output from the controller to the spindle controller. It is mainly output during syn-
chronous tap control.
Note
(1) While the "Spindle servo-ON" signal is ON, the "Spindle forward run start" (SRN), "Spindle reverse run start" (SRI),
and "Spindle orientation command" (ORC) signals are ignored.
(2) This signal is valid only for systems that are high-speed serially coupled to the spindle controller.
Cont. Signal name
A In spindle forward run
[Function]
This signal is output from the spindle controller (spindle drive) with high-speed serial coupling specifications and informs
that the spindle is rotating in the forward direction.
[Operation]
The "In spindle forward run" signal (SSRN) turns ON when the spindle motor is rotating in the forward direction.
This signal also turns ON if the spindle motor is rotating in the forward direction during orientation or synchronous tap.
Spindle motor speed
In spindle forward run
(SSRN)
Note
(1) The "In spindle forward run" signal (SSRN) turns ON and OFF while the spindle motor is in the stop state with servo
rigidity during oriented motion or synchronous tap.
(2) This signal is valid only for systems that are high-speed serially coupled to the spindle controller.
