10. SPINDLE SPEED FUNCTION

B-64693EN-1/01

- 1794 -

Spindle stop signal *SSTP<Gn029.6>

[Classification] Input signal

[Function] This signal stops the command output to the spindle.

[Operation] When this signal becomes 0, the command output to the spindle becomes 0, resulting in

the enable signal becoming 0. So, M05 is not output. When this signal becomes 1, the
command output to the spindle resumes its previous value, resulting in the enable signal
becoming 1.

The timing chart above is illustrative only. To be more precise, follow a timing chart that
meets the specification of the speed control unit for the spindle motor in use.
-

Keep this signal set to 1 unless it is used.

The CNC uses the commands M03, M04, and M05 to send only code and strobe
signals.

Individual spindle stop signals

*SSTP1<Gn027.3> *SSTP2<Gn027.4> *SSTP3<Gn027.5> *SSTP4<Gn026.6>

[Classification] Input signal

[Function] These signals are usable only during multi-spindle control.

They cause the respective spindles to stop.

*SSTP1 1: Does not make the output to the first spindle 0 min

-1

0: Makes the output to the first spindle 0 min

-1

*SSTP2 1: Does not make the output to the second spindle 0 min

-1

0: Makes the output to the second spindle 0 min

-1

*SSTP3 1: Does not make the output to the third spindle 0 min

-1

0: Makes the output to the third spindle 0 min

-1

*SSTP4 1: Does not make the output to the fourth spindle 0 min

-1

0: Makes the output to the fourth spindle 0 min

-1

Spindle speed override signals SOV0 to SOV7<Gn030>

[Classification] Input signal

[Function] These signals enable an override of 0% to 254% of the S command value sent to the CNC

to be applied to the spindle in 1% increments.

[Operation] Specify an override value in binary, using the 8 bits SOV0 to SOV7.

The spindle speed override specified with these signals becomes disabled, and an override
of 100% is applied to the spindle speed during:
-

Tapping cycle (for the M series, G84 and G74 or, for the T series, G84 and G88)

Threading mode (for the M series, G33 or, for the T series, G32, G92, and G76)

→ Specify an override of 100% unless this function is used.

(An override of 0% is applied, preventing spindle rotation.)

Spindle enable signals ENB<Fn001.4> ENB2<Fn038.2> ENB3<Fn038.3>

ENB4<Fn039.1>

[Classification] Output signal

[Function] These signals inform whether there is an output to the second, third, or fourth spindle if

the multi-spindle control is available.
The signals can be used as a condition for stopping the analog spindle and in PMC ladder
sequences related to rigid tapping.
(See Subsection, "Rigid Tapping.")

[Output cond.]

ENB 1 if the output to the first spindle control unit is not 0.

0 if the output to the first spindle control unit is 0.

ENB2 1 if the output to the second spindle control unit is not 0.

0 if the output to the second spindle control unit is 0.

ENB3 1 if the output to the third spindle control unit is not 0.

0 if the output to the third spindle control unit is 0.

ENB4 1 if the output to the fourth spindle control unit is not 0.

0 if the output to the fourth spindle control unit is 0.

Multi-spindle address P signals MSP00 to MSP15<Fn160.0 to Fn161.7>

[Classification] Output signal

[Function] These signals output the P value most recently specified by the S_ P_ ; command.

[Output cond.] If the address P-based multi-spindle control is enabled (bit 3 (MPP) of parameter No.

3703 =1), the P value specified by the S_ P_ ; command is output. If no S_ P_ ; has been
issued since application of the power, the initial P value specified in parameter No. 3775
is output.

Notes

Unlike spindle motors, servo motors stop if a servo alarm, emergency stop, or machine lock
condition occurs.

Specify an M code not involved in buffering as an M code to be used as a command for switching
the SV speed control mode (parameters Nos. 3411 to 3420 and 11290 to 11299).

M code for switching the SV speed control mode must be specified in an independent block.

When using multiple M commands in a single block, the M code must be specified as the first M

command.

G96.1, G96.2, G96.3, G96.4, and M code for switching the SV speed control mode must be
specified in the path to which the spindle of interest belongs.

The actual maximum motor speed is determined by applying a feed gear factor to the maximum
motor speed specified in parameter No. 11015.

If bit 3 (IRC) of parameter No. 1408 is 0, the malfunction prevent function may work at a rotation
speed of about 2778 min-1. To allow the motor to run at 2778min-1 or faster, set bit 3 (IRC) of
parameter No. 1408 to 1. If the bit is set to 1, the command can specify a rotation speed of up to
about 27778 min

-1

This function must be set for type T gears.

G96.1, G96.2, G96.3, G96.4 cannot be commanded for settings other than multi-spindle control type
P.

Feed axis synchronous control or synchronous control cannot be performed on an axis that is in SV
rotation control mode.

As for the axis used for spindle control with a servo motor, disable the setting of bit 7 (ALGx) of
parameter No. 1814, which adjusts the loop gain in Cs contour control mode to the loop gain of the
Cs contour control axis, and the setting of parameter No. 3900 and after, which sets the loop gain of
the axis to interpolate with the Cs contour control axis. Otherwise, the loop gain of the servo axis
will change suddenly if the system enters Cs contour control mode during rotation control.

When using spindle control with servo motor, set 1 to bit 3 (FEX) of parameter No.8003.

1022

Setting of each axis in the basic coordinate system

[Input type] Parameter input

[Data type] Byte axis

[Valid data range] 0 to 7

To determine a plane for circular interpolation, cutter compensation, and so forth (G17:
Xp-Yp plane, G18: Zp-Xp plane, G19: Yp-Zp plane) specify which of the basic three
axes (X, Y, and Z) is used for each control axis, or a parallel axis of which basic axis is
used for each control axis.
A basic axis (X, Y, or Z) can be specified only for one control axis.
Two or more control axes can be set as parallel axes for the same basic axis.

With an axis for which Cs contour control/spindle positioning is to be performed, set
-(spindle number) as the servo axis number.
Example)

When exercising Cs contour control on the fourth controlled axis by using the
first spindle, set -1.

For tandem controlled axes or electronic gear box (EGB) controlled axes, two axes
need to be specified as one pair. So, make a setting as described below.
Tandem axis: For a master axis, set an odd (1, 3, 5, 7, 9, ...) servo axis number. For a

slave axis to be paired, set a value obtained by adding 1 to the value
set for the master axis.

EGB axis:

For a slave axis, set an odd (1, 3, 5, 7, 9, ...) servo axis number. For a
dummy axis to be paired, set a value obtained by adding 1 to the value
set for the slave axis.

Maximum cutting feedrate for each axis

[Input type] Parameter input

[Data type] Real axis

[Unit of data] mm/min, inch/min, deg/min (machine unit)

[Min. unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (C)

(When the increment system is IS-B, 0.0 to +999000.0)
Specify the maximum cutting feedrate for each axis.

1432

Maximum cutting feedrate for all axes in the acceleration/deceleration before interpolation

[Min. unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (C)

(When the increment system is IS-B, 0.0 to +999000.0)
Set a maximum cutting feedrate for each axis in the look-ahead acceleration/deceleration
before interpolation mode such as AI contour control. When this parameter is set to 0 or
the look-ahead acceleration/deceleration before interpolation mode is not set, the
maximum cutting feedrate set in parameter No. 1430 is used.

1825

Servo loop gain for each axis

[Input type] Parameter input

[Data type] Word axis

[Unit of data] 0.01/sec

[Valid data range] 1 to 32767

Set the loop gain for position control for each axis.
When the machine performs linear and circular interpolation (cutting), the same value
must be set for all axes. When the machine requires positioning only, the values set for
the axes may differ from one another. As the loop gain increases, the response by position
control is improved. A too large loop gain, however, makes the servo system unstable.
The relationship between the positioning deviation (the number of pulses counted by the
error counter) and the feedrate is expressed as follows:
Positioning deviation = Feedrate / (60

Loop gain)

  Unit : Positioning deviation    mm, inch or deg
Feedrate  mm/min, inch/min, or deg/min
Loop gain    1/sec

1826

In-position width for each axis

[Input type] Parameter input

[Data type] 2-word axis

[Unit of data] Detection unit

[Valid data range] 0 to 99999999

The in-position width is set for each axis.
When the deviation of the machine position from the specified position (the absolute
value of the positioning deviation) is smaller than the in-position width, the machine is
assumed to have reached the specified position. (The machine is in the in-position state.)

[Data type] 2-word axis

[Unit of data] Detection unit

[Valid data range] 0 to 99999999

Set an in-position width for each axis in cutting feed. This parameter is used when bit 4
(CCI) of parameter No. 1801=1.

1828

[Input type] Parameter input

[Data type] 2-word axis

[Unit of data] Detection unit

[Valid data range] 0 to 99999999

Set the positioning deviation limit in movement for each axis.
If the positioning deviation exceeds the positioning deviation limit during movement, a
servo alarm SV0411, “EXCESS ERROR (MOVING)” is generated, and operation is
stopped immediately (as in emergency stop).
Generally, set the positioning deviation for rapid traverse plus some margin in this
parameter. Refer to the following set value.

NOTE

1 Usually, this value is parameter No.1420. When the maximal

feedrate of each axis exceeds parameter No.1420 according to the
command and override, the value is the maximal feedrate of the
each axis.

When a multi-path system is used, inter-path spindle control allows:

Configuration where the spindle that belongs to one path only is shared between
path 1 and path 2.

Configuration where the spindles that belong to path 1 and 2 are shared between the
two paths.

When the spindle that belongs to an arbitrary path is shared between arbitrary paths, set
bit 2 (MPM) of parameter No. 3703. (The meanings of signals used vary, so that ladder
program modifications need to be made.)
