Path spindle feedback selection signal SLPCA<G0064.2>,SLPCB<G0064.3>

[Function] You need not control the path spindle feedback selection signal because the spindle

feedback signal of path 1 is always effective to paths 1 and 2.

Path spindle command confirmation signal COSP <F0064.5>

[Classification] Output signal

[Function] This signal notifies which path the spindle command last specified came from.

[Output cond.] This signal becomes 1 under the following condition:

A spindle command is issued from path 2.

This signal becomes 0 under the following condition:
-

A spindle command is issued from path 1, or no spindle command is issued from
either path.

In the state in which spindle commands for both paths 1 and 2 are effective to the spindles
belonging to path 1, this signal allows you to determine which path the spindle command
last specified came from.

NOTE

Spindle commands refer to S code commands, maximum speed
command (G50S), M03/M04/M05, and commands for the constant
surface speed control (G96 and G97).

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.

using Spindle selection signals (SWS1 to SWS4<G027.0 to 2, G026.3>) is:

the position coder signals (PC2SLC<Gn028.7>, PC3SLC<Gn026.0>,

spindles that belong to a path selected by the inter-path spindle feedback selection
signals:
0:

The signals of the path selected by the inter-path spindle feedback selection signal
are used.

The signals of the local path are used.

Suppose that path x is selected by the inter-path spindle feedback selection signals
(SLPCA<Gn064.2>, SLPCB<Gn064.3>, SLPCC<Gn403.4>, SLPCD<Gn403.5>). Then,
the following position coder is selected in path x by the position coder selection signals:
n = m(path number)-1
y = x(path number selected by the spindle feedback selection signals)-1

P code for selecting the spindle in multi-spindle control

[Input type] Parameter input

[Data type] Word spindle

[Valid data range] 0 to 32767

If bit 3 (MPP) of parameter No. 3703 is set to 1, set the P code to select each spindle
under multi-spindle control. Specify the P code in a block containing the S command.

[Example] If the P code value for selecting the second spindle is set to 3,

S1000 P3;
causes the second spindle to rotate at S1000.

NOTE

1 This parameter is valid if bit 3 (MPP) of parameter No. 3703 is set

to 1.

2 If this parameter is set to 0, the corresponding spindle cannot be

selected by a P code.

3 Under multi-path control, the P code specified here is valid for each

path.
For instance, if the P code to select the first spindle of path 2 is set
to 21, specifying S1000 P21; in path 1 causes the first spindle of
path 2 to be rotated at S1000.

4 Identical P code values cannot be used for different spindles.

(Identical P code values cannot be used even if the paths are
different.)

5 When this parameter is used (when bit 3 (MPP) of parameter No.

3703 is set to 1), the spindle command selection signal is invalid.

6 To use this parameter, enable multi-spindle control (bit 3 (MSP) of

parameter No. 8133 is 1).

ILLEGAL SPINDLE NUMBER

In a spindle select function by address P for a multiple spindle
control,
1) Address P is not specified.
2) Parameter No. 3781 is not specified to the spindle to be

selected.

3) An illegal G code which cannot be commanded with an

S_P_; command is specified.

4) The multi spindle cannot be used because the bit 1 (EMS)

of parameter No. 3702 is 1.

5) The spindle amplifier number of each spindle is not set in

parameter No. 3717.

6) A prohibited command for a spindle was issued

(parameter No. 11090).

7) An invalid value is set in parameter No. 11090.

Note

NOTE

Signals used to operate the spindle control unit are not influenced by path
spindle command selection signals; process them with a PMC Ladder program,
if required.
(Example: SFRA<G0070.5> is always a forward rotation command to the first
serial spindle control amplifier of path 1.)

MEMORY COMMON TO PATHS

Overview

In a multipath system, this function enables data within the specified range to be accessed as data
common to all paths. The data includes tool compensation memory and custom macro common variables.

Explanation

Tool compensation memory

Part or all of tool compensation memory for individual paths can be used as common data by setting
parameter No. 5029.

NOTE

1 Set a value less than the number of tool compensation values for each path for

parameter No. 5029.

2 If the value set for parameter No. 5029 is greater than the number of tool

compensation values for each path, the minimum number of tool compensation
values for individual paths is assumed.

Custom macro common variables

All or part of custom macro common variables #100 to #149 (or #199) and #500 to #599 (or #999) can be
used as common data by setting parameters Nos. 6036 (#100 to #149 (, #199, or #499)) and 6037 (#500
to #599 (or #999)).

assumed.
