ILLEGAL AXIS
OPERATION

- A move command is commanded from the CNC on the servo motor in

servo motor spindle control mode.

- A move command is commanded from the CNC on the servo motor in

acceleration/deceleration of servo motor spindle synchronization mode.

- A move command is commanded from the CNC on the servo motor in

servo motor spindle synchronization mode when differential speed
synchronization command signal DFSYC and the servo motor spindle
switching signal SVSP set to “1”.

Notes

Servo/Spindle synchronous control (FSSB type)

The separate detector interface unit becomes unnecessary by the FSSB communication between a CNC
and a spindle amplifier.
However, if the separate detector interface unit is used, do not set the setting (the parameters FHRSV (bit
2 of No.2429) and FHESP (bit 2 of No.4549) of Servo/Spindle synchronous control (FSSB type).
Refer to "11.22.2 Servo/Spindle synchronous control (FSSB type)" for details.

Servo alarm

If a servo alarm occurs, servo spindle control and servo spindle synchronization mode are canceled. If this
occurs, SVSPM, SYSSM, SVAR, and SYAR (<Fn090> signals) are all cleared.
After the servo alarm is canceled, servo spindle control and servo spindle synchronization will be enabled
again.

Servo off

If follow-up is performed (bit 0 (FUPx) of parameter No. 1819 = 0), servo spindle control and servo
spindle synchronization mode are canceled. If this occurs, SVSPM, SYSSM, SVAR, and SYAR
(<Fn090> signals) are all cleared.

- 1859 -

If follow-up is not performed (bit 0 (FUPx) of parameter No. 1819 = 1), servo spindle control and servo
spindle synchronization mode are not canceled. Commands are accumulated as servo errors.

Emergency stop

In the event of an emergency stop, servo spindle control and servo spindle synchronization mode are
canceled. If this occurs, SVSPM, SYSSM, SVAR, and SYAR (<Fn090> signals) are all cleared.
After the emergency stop is canceled, servo spindle control and servo spindle synchronization will be
enabled again.

Multi-path
-

Number of axes

Only a single servo axis per path can be used with this function.

Signal address

If the servo motor on the second path is used, the addresses of all control signals are the original ones plus
1000.
Similarly, for the third path, the addresses are the original ones plus 2000.

Synchronization between paths

It is possible to synchronize between paths. To do this, input the signal for the path to which the servo
axis belongs.
For example, to synchronize the spindle on path 1 with the servo axis on path 2, input the signal on path 2
(G1000 to G1999).

Synchronization of multiple axes

It is possible to synchronize multiple servo axes to a single main-spindle. To do this, input the signals on
the multiple paths to which the servo axes belong.
It is necessary to connect multiple position coders to the same main-spindle and input them to the
connectors of the respective pulse modules.

10.22.2

Servo/Spindle Synchronous Control (FSSB Type)

Outline

By the FSSB communication between a CNC and a spindle amplifier, rotational position information of a
spindle can be transmitted from a spindle amplifier to a servo control on CNC. Servo/Spindle
synchronous control (FSSB type) is a function that a servo axis follows a spindle axis by utilizing this
FSSB communication. And it is a feature of this function that the separate detector interface unit becomes
unnecessary compared with the ordinary function.

Explanation

The amplifier of main-spindle (spindle motor) and the amplifier of sub-spindle (servo motor) used for
Servo/Spindle synchronous control (FSSB type) need to be connected to the main servo card. The spindle
amplifier and the servo amplifier used for Servo/Spindle synchronous control (FSSB type) can be
connected to both the first FSSB line and the second FSSB line. (This function can be executed between
two motors connected to another line.)

Ex.1) Servo/Spindle synchronous control (FSSB type) with A axis and S1 spindle axis in the one path
system.

10.22.3

Phase Synchronization for Servo/Spindle Synchronous
Control

Outline

There are three functions on Servo/Spindle synchronous control.
(a) Servo motor spindle control

Can rotate the servo motor at the rotation speed specified with an input signal.

(b) Servo motor spindle synchronization

Can rotate the servo motor in synchronization with the feedback pulses from the spindle sensor.

(i) Can superimpose a command from the CNC on the servo motor in servo motor spindle

synchronization.

(ii) Can superimpose the rotation speed specified with an input signal on the servo motor in servo

motor spindle synchronization.

By this function, the phase of sub-spindle (the servo motor machine coordinate zero point in the status of
reference position establishment) can match the phase of main-spindle (the spindle sensor position
determined by the one-rotation signal) on (b) Servo motor spindle synchronization.
Addition, the phase can be shifted by the parameter.

Refer to the manual CONNECTION MANUAL (FUNCTION) (B-64693EN-1) "11.22.1  Servo/Spindle
synchronous control" for the basic specification of Servo/Spindle synchronous control.

It is necessary to set Servo/Spindle synchronous control (FSSB type).  Refer to the manual
CONNECTION MANUAL (FUNCTION) (B-64693EN-1) "11.22.2  Servo/Spindle synchronous control
(FSSB type)" for details.

Enable spindle synchronous control (bit 4 (SYC) of parameter No.8133 is 1) for this function.

Explanation

The phase of sub-spindle (the servo motor machine coordinate zero point in the status of reference
position establishment) can match the phase of main-spindle (the spindle sensor position determined by
the one-rotation signal). Addition, the phase can be shifted by the parameter No.3845.
The method of phase synchronization is shown as follows.

(1) Establish the reference position of sub-spindle (servo motor) by Reference position establishment.

(Reference position establishment signals ZRFx <Fn120.x> is "1")

(2) Execute spindle orientation of main-spindle (spindle motor).
(3) When Servo motor spindle synchronization start signal SYSS <Gn061.2> is set "1", it becomes

servo motor spindle synchronization mode.

(4) When it becomes servo motor spindle synchronization mode, Servo motor spindle synchronization

mode signal SYSSM <Fn090.5> becomes "1".

(5) When it becomes servo motor spindle synchronization mode, sub-spindle accelerates or decelerates

to the rotation speed of main-spindle.

(6) When the acceleration/deceleration of sub-spindle is completed, Servo motor spindle

synchronization mode acceleration/deceleration completion signal SYAR <Fn090.4> becomes "1".

- 1865 -

(7) When Phase synchronization for Servo/Spindle synchronous start signal SYPST <Gn517.7> is set

"1" after the acceleration/deceleration of sub-spindle is completed, phase synchronization starts.

(8) The shift value between main-spindle and sub-spindle can be set by parameter No.3845.
(9) It accelerates or decelerates from the current spindle motor speed to the setting speed of parameter

No.3846 by Linear acceleration/deceleration with the acceleration rate based on parameter No.3843.

(10) When the synchronization error pulse value become small value more than allowable error pulse

value set by parameter No.3847, Phase synchronization for Servo/Spindle synchronous finished
signal SYPFN <Fn527.6> becomes "1".

(11) After Phase synchronization for Servo/Spindle synchronous finished signal SYPFN <Fn527.6>

becomes "1", set "0" to Phase synchronization for Servo/Spindle synchronous start signal SYPST
<Gn517.7>.

(12) When Servo motor spindle synchronization start signal SYSS <Gn061.2> is set "0", servo motor

spindle synchronization mode is canceled.

(13) Servo motor spindle synchronization mode acceleration/deceleration completion signal SYAR

<Fn090.4> and Phase synchronization for Servo/Spindle synchronous finished signal SYPFN
<Fn527.6> become "0".

(14) Sub-spindle decelerates and stops.
(15) When the acceleration/deceleration of sub-spindle is completed, Servo motor spindle

synchronization mode signal SYSSM <Fn090.5> becomes "0".
