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.
