NOTE

When this parameter is set, the power must be turned off Before
operation is continued.

When a spindle is set as a slave spindle in spindle synchronization control on each

spindle, set which spindle (master spindle) the slave spindle is to be synchronized with.

NOTE

1 This parameter is valid if bit 4 (SSS) of parameter No. 3704 is set

to 1 (to enable spindle synchronization based on arbitrary spindles)
for the path to which a slave spindle belongs and for the path to
which a master spindle belongs.

2 The setting of a slave spindle as a master spindle is invalid. Be

sure to set 0 for a spindle that is to function as a master spindle.

3 In this parameter, set a spindle number common to the system.

When this parameter is used, parameter No.4831 is set to 0.

Notes

NOTE

1 Output signal SYCAL<Fn044.4> is used for monitoring a phase shift in

synchronous control. Whether the processing is performed when a phase shift is
detected depends on the specifications determined by the machine tool builder.

2  A gear ratio of 1 : 1 only is allowed between the spindle and position coder.
3  A CNC system restriction is imposed on the maximum number of spindles.
4  If the speed at the spindle synchronous mode exceeds maximum speed of slave

spindle, an alarm PS0447 “ILLEGAL SETTING DATA” occurs.

5 Master spindle and slave spindle stop rotating due to a servo alarm, emergency

stop, machine lock, etc.

6 When using this function, enable the spindle synchronous control function (bit 4

(SYC) of parameter No,8133 is 1).

10.20.10

Improvement of Spindle Stop Motion for Spindle Control with
Servo Motor

Overview

If SV speed control mode is canceled during spindle rotation, spindle indexing is executed and spindle is
stopped at specified position so far. When bit 0 (NSP) of parameter No.11002 is set to 1, If SV speed
control mode is canceled during spindle rotation, spindle indexing is not executed and spindle is
decelerated and stopped. When spindle indexing is unnecessary, machining cycle time can be reduced.

Format

When bit 0 (NSP) of parameter No.11002 is set to 1:

G96.1 P_ ; The operation of the next block is started after deceleration

stop of spindle.

G96.2 P_ ; The operation of the next block is started before deceleration

stop of spindle.

G96.1 P_ R_ ; The operation of the next block is started after completing

spindle indexing.

G96.2 P_ R_ ; The operation of the next block is started before completing

spindle indexing.

G96.3 P_ ; The operation of the next block is started after confirming

completion of spindle indexing.

P : Spindle selection with multi-spindle control
R : Stoppage angle [deg] (0 to (parameter No.1260))

NOTE

1 When using G96.2, issue G96.3 before another spindle move command, to

make sure that the spindle is at a complete halt.

2 To issue G96.1, G96.2, or G96.3, use an independent block.

Explanation

When bit 0 (NSP) of parameter No.11002 is set to 1, if SV speed is canceled during spindle rotation,
spindle indexing is not executed and spindle is decelerated and stopped.

Command with a program

When R address is not commanded at G96.1 block, spindle indexing is not executed and spindle is
decelerated and stopped. SV speed control mode in-progress signal SVREV<Fn521> becomes “0” after
deceleration stop of spindle, and SV speed control mode is canceled. Then, the next block is started.
When also R address is not commanded at G96.2 block as well, spindle indexing is not executed and
spindle is decelerated and stopped. If G96.2 is commanded, the next block is started without waiting
deceleration stop of spindle. If G96.3 is commanded, SV speed control mode in-progress signal
SVREV<Fn521> becomes “0”, and SV speed control mode is canceled. When R address is commanded
at G96.1 or G96.2 block, spindle indexing is executed and spindle is stopped at specified position.

Command with a signal

When SV speed control mode signal SRVON<Gn521> is set to “0”, spindle indexing is not executed and
spindle is decelerated and stopped. SV speed control mode in-progress signal SVREV<Fn521> becomes
“0” after deceleration stop of spindle, and SV speed control mode is canceled.

For details, refer to "Reading diagnosis data (function code 33) in Chapter 5, "Window Functions", in the
PMC Programming Manual (B-64513EN).

As for total revolution number display data, the total revolution number data for a specified diagnosis
data number can be cleared for a specific spindle, using the signals below.
-

Using the total spindle revolution number reset selection signal SSRS <Gn533.4>, select the
diagnosis data number of the total revolution number data to be cleared.

Using an appropriate total spindle revolution number reset signals SSR1 to SSR4 <Gn533.0 to
Gn533.3>, clear the total revolution number data for a specific spindle.

NOTE

1 When using this function, enable the spindle serial output (bit 5 (SSN) of

parameter No,8133 is 0).

2 Storage of spindle revolution number data in data-retention memory is

performed at intervals of about one second. If the power is turned off while a
spindle is revolving, revolution number data is not stored for about one second
before the power is turned off.

3 This function is effective to a built-in spindle motor and to a spindle configuration

in which a spindle and a spindle motor is connected together at a gear ratio of
1:1.

4 If the spindle switching function (a configuration in which one set of

main/sub-spindle motors are connected to a single spindle amplifier) is used,
total revolution number data is counted as an integrated value of two spindles.

SERVO/SPINDLE SYNCHRONOUS CONTROL

10.22.1

Servo/Spindle Synchronous Control

Overview

This function provides the following functions to use a servo motor as a spindle:
(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 position coder of
the spindle.

(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.

NOTE

When using this function, enable the spindle synchronous control (bit 4 (SYC) of
parameter No,8133 is 1).

Explanation

Connection

Input feedback pulses from the position coder to the pulse module.
To make effective the feedback pulses input to the pulse module, set parameters Nos. 24096 to 24103.
This causes the spindle (position coder) and the servo motor to synchronize with each other.

NOTE

During operation, the combination of spindle and servo motor to synchronize
cannot be changed.

Configuration

To use this function, the detection unit must be specified by setting the flexible feed gear (M/N)
(parameter No.2084 and 2085) in such a way that the number of pulses per rotation of the spindle will be
4096. Thus, it is necessary to select a servo motor-to-spindle gear ratio a:b so that the M and N values of
the flexible feed gear as determined from the expression below will be equal to or less than 32767.

= ×

4 096

1 000 000

To perform servo motor and spindle synchronous control, set a magnification (integral multiple or R) so
that the number of feedback pulses from the position coder will be 4096 per rotation of the spindle. That
is, the gear ratio of the position coder to the spindle must be one to an integer.

Spindle-side gear

: 8,000

Servo motor-side gear

If these settings are made, a normal move command for the A-axis will be A4.096 per rotation of the
spindle, and the speed command will be a feed per minute command per rpm, F4.096.

The magnification (R) for servo motor and spindle synchronous control will be set to 2 because the gear
ratio of the position coder to the main-spindle is 1:2.

Servo motor spindle control

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

Servo motor spindle control mode

By setting the servo motor spindle switching signal SVSP <Gn022.7> to “1”, the system enters servo
motor spindle control mode, so that the servo motor can be rotated at the rotation speed specified with a
signal.
In servo motor spindle control mode, the servo motor spindle control mode signal SVSPM <Fn090.7> is
set to “1”.
By setting SVSP to “0”, servo motor spindle control mode is canceled. If this occurs, SVSPM is set to
“0”.

NOTE

1 In servo motor spindle control mode, coordinates will not be updated. Thus, the

relationships between coordinates and actual machine position will be lost.

2 If a move command is commanded from the CNC on the servo motor in servo

motor spindle control mode, alarm PS5211 “ILLEGAL AXIS OPERATION” is
issued.

Specifying a motor rotation speed

The rotation speed of the servo motor in servo motor spindle control mode can be specified with the servo
motor rotation speed specification signals SVR01I to SVR12I <Gn021.0 to Gn022.3>. Set the setting
determined from the formula below, in binary notation.

Acceleration/deceleration

If servo motor spindle control mode is turned on or off or if the rotation speed specified with SVR01I to
SVR12I changes, acceleration/deceleration is performed with the time constant set in parameter No. 3843.
When a steady state is attained after the completion of acceleration/deceleration, the servo motor spindle
control mode acceleration/deceleration completion signal SVAR <Fn090.6> is set to “1”.
