[Valid data range] 0 to 8

When a touch sensor with one contact signal input is used for the "direct input of offset
value measured B" function or when the movement direction determination specification
is enabled, set the number of interpolation cycles of pulses stored until the tool is about to
touch the touch sensor by manual operation. When 0 is set, the specification of the
maximum value 8 is assumed.

NOTE

This parameter is valid when bit 3 (TS1) of parameter No. 5004 or bit
4 (TSD) of parameter No. 5009 is set to 1.

NOTE

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

[Valid data range] 0 to 999

Set the maximum allowable number of tool compensation values used for each path.
Ensure that the total number of values set in parameter No. 5024 for the individual paths
is within the number of compensation values usable in the entire system. The number of
compensation values usable in the entire system depends on the option configuration.
If the total number of values set in parameter No. 5024 for the individual paths exceeds
the number of compensation values usable in the entire system, or 0 is set in parameter
No. 5024 for all paths, the number of compensation values usable for each path is a value
obtained by dividing the number of compensation values usable in the entire system by
the number of paths.
Tool compensation values as many as the number of compensation values used for each
path are displayed on the screen. If tool compensation numbers more than the numbers of
compensation values usable for each path are specified, alarm PS0115 “VARIABLE NO.
OUT OF RANGE” is issued.
For example, 64 tool compensation sets are used, 20 sets may be allocated to path 1, 30
sets to path 2, and 14 sets to path 3. All of 64 sets need not be used.

15.4.3

Chattering Prevention of "Direct Input of Offset Value
Measured B"

Overview

This function is provided by the "direct input of offset value measured B" function to prevent an invalid
offset value from being set even when the input signal from a touch sensor chatters due to mechanical
vibration.

Explanation

If the "direct input of offset value measured B" function encounters a chattering input signal from a touch
sensor, for example, due to mechanical vibration, the same signal input later can be ignored. Once an
offset value is measured with a signal from the touch sensor, any signal input that follows is rejected until
movement over at least the distance set by parameter No. 5019 later is specified. Signals are ignored if
input.

Assuming that an offset value is measured correctly at point A in Fig. 15.4.3 (a), even when movement
from A to B is specified, measurement at point C is invalid and ignored as the travel distance is smaller
than the setting of parameter No. 5019.

When movement from A to D is specified, measurement at point E is valid and an offset value is
measured as the travel distance is larger than the setting of parameter No. 5019.

Next measurement is enabled when travel
distance after measurement exceeds the
setting of parameter No. 5019.

Once a signal is input from a touch sensor, any signal input from the touch sensor is

setting is 0, this function is disabled and any input from the touch sensor is always
accepted. Note that changing the setting of this parameter cancels the input signal
ignoring status.

PMC CONTROL FUNCTION

16.1

PMC AXIS CONTROL

16.1.1

PMC Axis Control

Overview

The PMC signals can directly control any given axis, independent of the CNC. An axis can be controlled
by signals alone without using an NC program. For example, by specifying an amount of travel, feedrate,
and so forth from the PMC, a movement can be made along an axis independently of other axes operated
under CNC control. This enables the control of turrets, pallets, index tables and other peripheral devices
using any given axes of the CNC.
Whether the CNC or PMC controls an axis is determined by the input signal provided for that particular
axis.

Table 16.1.1 (a) Commands that can be executed by PMC axis control

Rapid traverse
Cutting feed - feed per minute
Cutting feed - feed per revolution
Skip - feed per minute
Dwell
Reference position return
Continuous feed
1st to 4th reference position return
External pulse synchronization - Position code
External pulse synchronization - 1st to 3rd manual handle
Feedrate control command
Torque control command
Auxiliary function, Auxiliary function 2, Auxiliary function 3
Selection of the machine coordinate system
Cutting feed - sec/block specification

NOTE

Ladder sequence of the PMC axis control can be easily incorporated by using
PMC function. Functional instruction AXCTL(Axis Control Command by PMC:
SUB 53) that can easily realize the PMC axis control command is provided.

In the FANUC LADDER-III CD, function block that can be incorporated easily
arious PMC axis control command is stored in the form of a library.

For details on functional instruction AXCTL and function block, refer to the PMC
Programming Manual (B-64513EN). For details on library of function block, refer
to the documents in the FANUC LADDER-III CD.

16. PMC CONTROL FUNCTION

B-64693EN-1/01

- 2504 -

Explanation

Under PMC axis control, various types of control are exercised using signals.
To allow the command that can be executed by PMC axis control operations indicated in Table 16.1.1 (a)
by PMC, maximum 16 groups of input/output signals are available. The groups are named group 1, group
2, ..., group 15, and group 16. (The number of available groups depends on the number of NC path.)
Each of these groups of input/output signals used with PMC axis control serves as the unit of PMC axis
control. Which axis is to be controlled by each group must be set in parameter No. 8010 beforehand.(See
Supplement 1 of Concept of PMC axis control Fig. 16.1.1 (a))
One group may be able to be assigned to multiple axes so that the same operation can be performed on
the multiple axes. (Supplement 2)
By commanding multiple groups at the same time, multiple axes can be controlled independently.
(Supplement 3)

(Supplement 1) The relationships between groups and axes are set in parameter No. 8010.

Signals

Three types of signals are used with PMC control:

Group-by-group signals are assigned to each group.

Axis-by-axis signals are assigned to each axis.

Path-by-path signals are assigned to each path.

Relationships between groups and axes (group-by-group signals)

Group-by-group signal addresses are allocated in the signal area of each path. (See Allocation of
group-by-group signals (Table 16.1.1 (b)).)
Note, however, that PMC axis control and multi-path control are independent of each other.

NOTE

The number of available groups depends on the number of NC path or type of
PMC.
In general, groups equal to 4 times the number of NC path are available.

The notation of group-by-group signals is described below.
For example, the group-by-group signals include the axis control command read signal EBUF (described
later). This signal is represented as:
EBUFg#p
A group number is represented by "p" and "g".
"g" is replaced with A, B, C, or D, and A = 1, B = 2, C=3, and D = 4 are assumed.
"p" is replaced with a number from 1 to 4.
A group number is related with "p" and "g" as follows:
Group number = g+(p-1)

EBUFA#1 represents group 1 (1+(1-1)

4).

EBUFB#2 represents group 6 (2+(2-1)

4).

EBUFC#3 represents group 11 (3+(3-1)

4).

EBUFD#4 represents group 16 (4+(4-1)

4).

Note, however, for the small letter of “g” or “p”, that a signal named EBUFg#p does not actually exist.

In the text, signal names such as "EBUFA", "EBUFB", "EBUFC", "EBUFD", and "EBUFg" are used.
Unless otherwise noted, these signal names are the abbreviations of "EBUFA#1" for group 1,
"EBUFB#1" for group 2, "EBUFC#1" for group 3, "EBUFD#1" for group 4, and "EBUFg#1 to
EBUFg#4" for general EBUF signals, respectively.

When assigning multiple axes to one group, set parameter No. 8010 so that the axes belong to the same
path. A setting in which the assigned axes do not belong to the same path is erroneous (see "Example of
incorrect relationships between groups and axes"). (Fig. 16.1.1 (c))
In Example of correct relationships between groups and axes (Fig. 16.1.1 (b)) , the first and second axes
specified with group 1 belong to the same path (path 1), and the third and fourth axes specified with
group 2 belong to the same path (path 2), so that operation is performed correctly.
