αi SERVO WARNING

INTERFACE

General

The αi servo system can report the warning status before one of the

following target alarms occurs.

When the warning status is entered, a report to the PMC is issued.

For example, this signal can be used by the machine for retracting tools

from the time a warning occurs by the time a servo alarm occurs.

Alarms with the αi servo

If SWP parameter (bit 2 of parameter No. 1807) = 0, a servo alarm, in

amplifier in the warning

addition to a warning signal, is issued when the αi servo amplifier gets

state

in the warning state.

The servo alarms listed below place automatic operation on feed hold,

thus decelerating all controlled axes (including the PMC axis) until they

stop.

These alarms will not de-energize the servo motors.

If the αi servo amplifier actually gets in the alarm state after any of the

above servo alarms with the servo amplifier in the warning state has

occurred, the servo motors are de-energized, resulting in an alarm with

the servo amplifier in the alarm state being displayed.

If SWP (bit 2 of parameter No. 1807) = 1, a warning signal, rather than

an alarm with the servo amplifier in the warning state, is issued when the

αi servo amplifier gets in the warning state. If the servo amplifier gets in

the warning state during automatic operation, the automatic operation

continues. In this case, decelerate each axis until they stop, using the

warning state signal before the servo motors are de-energized.

Otherwise, the motors may get de-energized in the middle of axis

movement.

INFORMATION

SCREEN

General

In the αi servo system, ID information output from each of the connected

units is obtained and output to the CNC screen.

The units that have ID information are shown below.

(Remark: Some instances of these units do not have ID information.)

S Servo motor

S Pulse coder

S Servo amplifier module

S Power supply module

ID information is automatically read from each of the connected units

during first startup of the CNC and then recorded. During the second or

later startup, the ID information recorded during first startup can be

compared with the ID information read this time on the screen to check

whether the configuration of the connected units is changed. (If there is

a difference between them, the alarm mark (*) appears.)

The recorded ID information can be edited. Therefore, the ID information

of an unit that does not have ID information can be displayed. (However,

the alarm mark (*) indicating a difference between these IDs appears.)

Additional Information

Even if replacement is performed reasonably such as for

repairing, this function incorrectly indicates the * mark when

it detects the replacement.

To clear the * mark, follow the steps below to update the

registered data, as described in the editing section later.

(1)Make the registered data editable. (Parameter IDW (No.

13112#0) = 1)

(2)On the edit screen, place the cursor on the item from

which you want to delete the * mark.

(3)Operate the soft keys [CHANGE], [INPUT], and [SAVE]

in that order.

Editing the servo ID screen

Assume that parameter No.13112#0(IDW) = 1.

Press the MDI switch on the machine operator’s panel.

Follow the steps shown in ”Displaying the servo ID screen” to display
