08.90 Introduction

1 Introduction

This planning instruction describes the PLC software ”Programming and Display functions” for WF 725 and/or WF 726 in SINUMERIK 3, GA4.

For many manufacturers of tool machines, it is desirable to be able to position auxiliary axes in addiition to the four axes which can be traversed over the NC control of the medium power class SINUMERIK 3, GA4.

With this, a tool magazine, a tool supplier or a loading portal could be realised with the tool machine.

With the help of the positioning modules WF 725 and/or WF 726, up to 21 additional auxiliary axes can be positioned without having to evade to an NC control of the higher class.

The PLC software described here fulfills the following functions: – Setting of a single traversing block to the WF 725 or WF 726

Traversing path, traversing feed rate and path conditions are set over R-parameters freely selectable in an NC part program. When the NC part program is executed, the data is transmitted to the WF 725 or WF 726, and the auxiliary axes are immediately traversed.

– Positioning of a tool magazine

Up to 120 magazine place positions can be selected over a parameter. The rotational direction - ”right”, ”left” or ”shortest distance” can also be selected.

– Input/Output of Machine data and Operating Data

With display masks, the data mentioned above can be entered and changed. This simplifies the start-up of the WF 725 or ”F 746.

– Display on the NC operator panel

The following data is shown for the selected axis

• Actual value

• Residual traversing path

• Feed rate

• Error Or for positioning of tool magazine axes:

• Magazine location command

• Actual magazine location

• Error

Introduction 08.90

Notes for use: The PLC software ”Programming and display functions” can be used in SINUMERIK 3, GA4B

or SINUMERIK 3, GA4C with single or double PLC. This applies for the following controls:

SINUMERIK 3T, 3TE SINUMERIK 3TT, 3TTE SINUMERIK 3M, 3ME SINUMERIK 3G, 3GE

SINUMERIK 3FA Up to seven WF 725 or WF 726 positioning modules can be used in a control. Prerequisite for the use of the PLC software descibed here is the use of the PLC software

”Basic functions” (see chapter 6.7).

2 Description of the functions

2.1 Auxiliary Axis

2.1.1 Description of the FB 203

With the FB-Auxiliary axis it is possible to enter a single traversing block in R-parameters into the NC and to transmit the block to the set axis with the help of M-functions. With a further M-function, the axis can be started. Parameterisation of the ”basic functions” must, however, be executed according to the start-up and planning instruction of the WF725/WF726.

The function block supplies the following functions:

• Transmission of path, feed rate and first G-function from the NC part program to the WF module with the help of R-parameters.

• Display of check back signals on the monitor screen of the NC. The following values are shown for each axis (BCD):

– Actual value – Residual path – Feed rate – 1st G-Function – Error messages of the WF725/WF726 – MODE of the module – Operating Submode of the axis – Wrong MODUS

– Wrong axis number in clear text The residual traversing path will only be updated with start. The axis number is selected over a parameter of the FB205.

2.1.2 Notes for use of the FB 203

• FBs to be loaded: ”Basic functions” (for use of WF725): FB207, 210, 211, 216 ”Basic functions” (for use of WF726): FB207, 210, 211, 215, 216, 217

• The block must be called once for each axis.

• To transmit an R-parameter from the NC to the WF 725/ WF 726, the user must decode the M-function set in the NC-program and set the corresponding bit in the parameter W-UE. The values of the R-parameter ranges from 0 to 999 999.

• The parameter DU-8 is set at the end of a data transmission for one cycle. The user can now start the corresponding axis.

• The user must realise the read-in disable and the read-in enable of the NC. The signal DU-L (Data transmission operating) can be used for this.

• The display buffer for the feed rate is in the DB79 of DW117, 118.

2.2 Tool magazine drive

2.2.1 Description of the FB 204

The tool magazine drive positions up to 3 tool magazines or turrets. The maximum number of magazine locations is 120 per axis. The command values for the single magazine locations are deposited in a DB in form of a table.

The function block supplies the following functions:

• Transmission of feed rate from the DB tool magazine drive to the WF725/WF726 (Axis

1...3)

• Calculation of command position from revolver/magazine location number and transmission to the WF725/WF726 (Axis 1...3)

• Output of the message ”Magazine position reached” after end of positioning.

• During conventional operation, the axis is traversed about 1 position each with the signals jog+/jog-. When jog+/jog- are continually signalled, then the next position is traversed to.

• Display of check back signals on the NC screen. For each axis, the following values are shown (BCD):

– present magazine location number – magazine location number to be traversed to – Error messages of the WF725/WF726 – MODE of the module – Operating submode of the axis – Wrong MODUS – Wrong axis number in clear text

If traversing is executed with jog+/jog-, the command magazoine location will not be updated, instead, the value is displayed which is set as a parameter. The axis number is selected with a parameter of the FB 205.

Der FB204 ermittelt aus der Magazinplatznummer anhand der Tabelle (DB WZ-M-A) den Positionswert für die WF725/WF726 und startet anschließend die angewählte Achse. Aus dem Istwert der von der Achse zurückgemeldet wird, wird durch Vergleich mit der Tabelle (DB-WZ-M-A) der momentan angefahrene Magazinplatz ermittelt und über den Parameter POSI im Dual-Code dem Anwender mitgeteilt. Ist der gewünschte Magazinplatz erreicht, wird ein Ausgangsparameter gesetzt. Das Signal Datenübertragung läuft wird ebenfalls als Parameter ausgegeben.

The FB204 calculates the position value for the WF 725/WF 726 from the magazine location number of the table (DB WZ-M-A). The FB then starts the selected axis. The presently traversed magazine location is calculated from the actual value signalled back from the axis by comparing with the table (DB-WZ-M-A). This value is then transmitted to the user in the binary code with the parameter POSI. If the desired magazine location is reached, then an output parameter is set. The signal Data transmission active is also read out as a parameter.

• The block must be called once for every tool magazine.

• If a magazine location is to be traversedm then the user must supply the signals RICH and POSS. When STAR is set on the 1-signal, the corresponding path is transmitted to the WF725/ WF 726, and the magazine is started at the end of the data exchange.

• The tool organisation must be realised by the user.
