Maximum speed
of spindle motor

(Spindle motor speed output)

Address P signals MSP00 to MSP15<Fn160.0 to Fn161.7>

[Classification] Output signal

[Function] The P value specified last by the S_P_; command is output.

When extended spindle names are used, the value in parameter No. 3781 corresponding
to the spindle number of the spindle name specified last is output.

[Output cond.] When multi-spindle control by using address P is enabled (bit 3 (MPP) of parameter No.

3703 is 1), the P value specified in the S_P_; command is output. When no S_P_;
command has been specified even once since power-up, the initial P value set in
parameter No. 3775 is output.
When extended spindle names are used, the value in parameter No. 3781 corresponding
to the spindle number of the spindle name specified last is output. When no spindle name
has been specified even once, the value set in parameter No. 3775 is output.

1st spindle speed override signal SOV0 to SOV7<Gn030>
2nd spindle speed override signal SOV20 to SOV27<Gn376>
3rd spindle speed override signal SOV30 to SOV37<Gn377>
4th spindle speed override signal SOV40 to SOV47<Gn378>

[Classification] Input signal

[Function] If bit 4 (EOV) of parameter No. 3713 = 1, an override of 0% to 254% of the rotation

speed specified by the CNC can be applied to individual spindles separately.

[Operation] Specify an override value, using an 8-bit binary number.

If all bits are 1, however, an override of 0% is assumed.

NOTE

If bit 4 (EOV) of parameter No. 3713 = 0, the override signals
SOV0 to SOV7 are applied to all spindles that receive speed
commands.
The signals SOV20 to SOV27, SOV30 to SOV37, and SOV40 to
SOV47 are invalid.

Spindle command path specification signal SPSP<Gn536.7>

[Classification] Input signal

[Function] Turns spindle command path specification ON or OFF.

[Operation] If a command based on address P (bit 3 (MPP) of parameter No. 3703 = 1 and bit 1

(ESN) of parameter No. 3798 = 0) or a command based on an extended spindle name (bit
3 (MPP) of parameter No. 3703 = 1, bit 0 (EEA) of parameter No. 1000 = 1, and bit 1
(ESN) of parameter No. 3798 = 1) is used in multi-spindle control:

B-64693EN-1/01

10. SPINDLE SPEED FUNCTION

- 1611 -

Setting this signal to 1 enables path specification for spindle commands.
Spindle commands can be issued from the path specified by parameter No. 11090.
If a spindle command is issued from a path other than the path, PS5305 alarm is
issued.

Setting this signal to 0 disables path specification for spindle commands.

Spindle commands can be issued from individual paths no matter what the setting of
parameter No. 11090.

#2 MPA

If a spindle is to be selected using a P command (with bit 3 (MPP) of parameter No. 3703

set to 1) in multi-spindle control, and a P command is not specified together with an S
command:
0:

The alarm PS5305, “ILLEGAL SPINDLE NUMBER” is issued.

The last P specified by S_ P_; (by S_ P_; specified for the path in case of a
multi-path system) is used. If P is not specified even once after power-up, the value
of parameter No. 3775 is used.

#4 GTT

Spindle gear selection method is:

Type M.

Type T.

NOTE

1 This parameter is effected for M system.
2 M type

The gear selection signal is not input. The CNC selects a gear
based on the speed range of each gear set by a parameter
beforehand according to S codes, and the selected gear is posted
by outputting the gear selection signal. Moreover, the spindle
speed matching the gear selected by the output gear selection
signal is output.

T type

The gear selection signal is input. The spindle speed matching the
gear selected by this signal is output.

3 When the constant surface speed control is enabled(bit 0(SSC) of

parameter No.8133 is 1), type T is selected, regardless of whether
this parameter is specified.

Set the number of gear teeth on the position coder side in speed control (such as feed per
revolution).

3722

Number of gear teeth on the spindle side

[Input type] Parameter input

[Data type] Word spindle

B-64693EN-1/01

10. SPINDLE SPEED FUNCTION

- 1617 -

[Valid data range] 0 to 9999

Set the number of gear teeth on the spindle side in speed control (such as feed per
revolution).

CAUTION

1 Parameter No.3721 and No.3722 can not be used for thread

cutting.
If thread cutting was done by setting the any value on these
parameters, the correct screw can't be cut.
In the machine to do thread cutting, connect mechanically between
the spindle and position coder by the gear ratio=1:1. And these
parameters set the No.3721=0, No.3722=0.
(It is the setting for the gear ratio 1:1.)

2 Parameter No.3721 and No.3722 can not be used for Cs contour

control. If Cs contour control was done by setting the any value on
these parameters, spindle can’t move as commanded. In the
machine to do Cs contour control, connect mechanically between
the spindle and position coder by the gear ratio = 1:1. And these
parameters set the No.3721=0, No.3722=0. (It is the setting for the
gear ratio 1:1.)

3738

Spindle name 2 of each spindle

3739

Spindle name 3 of each spindle

[Input type] Parameter input

[Data type] Byte spindle

[Valid data range] 48 to 57, 65 to 90

The command for a spindle is basically "S".
When all conditions below are satisfied, however, an extended spindle name can be used.
An extended spindle name consists of up to three characters starting with "S" as the first
spindle name. Thus, a command for a spindle can be specified.
-

The serial (analog) spindle function is enabled.

The multi-spindle control is enabled.

Bit 0 (EEA) of parameter No. 1000 is set to 1.

Bit 3 (MPP) of parameter No. 3703 is set to 1.

Bit 1 (ESN) of parameter No. 3798 is set to 1.

Bit 4 (GTT) of parameter No. 3706 is set to 1. (M series only)

As spindle name 2 (parameter No. 3738) and spindle name 3 (parameter No. 3739),
ASCII codes from 0 to 9 and A to Z can be arbitrary set. However, before spindle name 3
for a spindle can be valid, spindle name 2 must be set for the spindle. Moreover, when a
character from 0 to 9 is set as spindle name 2, do not set a character from A to Z as
spindle name 3.

NOTE

1 When an extended spindle name is used, a subscript (for a main

spindle (parameter No. 3718)) and a subscript (for a sub-spindle
(parameter No. 3719)) are unusable.

2 When the custom macro function is enabled, the same extended

spindle name as a reserved word must not be used. Such an
extended spindle name is regarded as a reserved word.
