CNC 8025 T, TS New Features (Ref. 0107 in) ERRORS FOUND IN THE PROGRAMMINGMANUAL (REF. 9701) Page 64. Function G51. When working in diameters, the "I" value in the table is in diameters and the value to be assigned to parameter "I" in the G51 function must always be given in radius. Section 12.4. (Chapter 12 page 133) Nesting levels. The figure reads M02 ó M30 It should read: M02 or M30 TING MANUAL (REF. 9701) ERRORS FOUND IN THE OPERA Page 46. Last paragraphs. It should say: The CNC asks which is the source program number and which is the new program number, after keying each one of them, press [ENTER]. If the number of the source program does not exist, or there is already a program in memory with the same number as the new one or if there is not enough when copying the new program , the CNC will issue a message indicating the cause. ALLATION MANUAL (REF. 9707) ERRORS FOUNDS IN THE INST Section 5.4 (chapter 5 page 7) Machine parameters for spindle control: Parameter P606(3) is missing: P606(3) Spindle counting direction It sets the spindle counting direction. If correct, leave it as it is or change it if otherwise. Possible values: "0" and "1". MODIFICATIONS TO THE INSTALLATION MANUAL (REF. 9707) Section 2.3.4 (chapter 2 page 9). Logic Outputs: In the table, the following output is missing: Output "C" Row 1: (pin 3 I/O 1) M strobe Row 2: (pin 5 I/O 2) output 3, decoded M function Section 3.3.3 (chapter 3 page 11). P602(4). Another example: Having a Fagor electronic handwheel (25 lines per turn) set as follows: P602(1)=0 Millimeters P501=1 Resolution 0.001 mm. P602(4)=0 x4 Multiplication factor Depending on the position of the MFO switch (Manual Feedrate Override), the selected axis will move: Position 1 1 x 25 x 4 = 0.100 mm per turn Position 10 10 x 25 x 4 = 1.000 mm per turn Position 100 100 x 25 x 4 = 10.000 mm per turn MODIFICATIONS TO THE LAN MANUAL (REF. 9701) Section 2.2 (page 3). P616(7) The first 2 paragraphs change. They should say: If "P616(7)=0" the 8025 T CNC uses pin 15 of connector I/O1 as the input for the Feed-Hold, Transfer-Inhibit and M-done signals as described in the Installation manual, chapter 1 section "Inputs of connector I/O 1" If "P616(7)=1" the CNC behaves as follows: * The Feed-Hold input will be "taken" ....... -2- Version 7.1 1. EXPANSION OF THE INTEGRATED PLC RESOURCES 1.1 INPUTS 1.1.1 TYPE OF FEEDRATE (G94/G95) PLCI input I86 will show at all times the type of feedrate (F) selected a the CNC. I86 = 0 I86 = 1 G94. Feedrate in millimeters (inches) per minute. G95. Feedrate in millimeters (inches) per revolution. (July 1996) 1.1.2 TYPE OF CUTTING SPEED (G96/G97) PLCI input I87 will show at all times the type of cutter speed selected at the CNC. I87 = 0 I87 = 1 G97. Constant tool center speed. G96. Constant cutting-edge speed 1.1.3 AXIS BEING HOMED (REFERENCED) Input I88 indicates whether a home search is taking place and inputs I100, I101, I102, I103 and I104 indicates which axis is being homed. I88 I100 I101 I102 I103 I104 Indicates whether any axis is being homed (0=No / 1=Yes) Indicates whether the X axis is being homed (0=No / 1=Yes) Indicates whether the 3rd axis is being homed (0=No / 1=Yes) Indicates whether the Z axis is being homed (0=No / 1=Yes) Indicates whether the 4th axis is being homed (0=No / 1=Yes) Indicates whether the C axis is being homed (0=No / 1=Yes) 1.1.4 AXIS MOVING DIRECTION Inputs I42, I43, I44 and I45 will show, at all times, the moving direction of each axis. I42 I43 I44 I45 Indicates the moving direction of the X axis (0=Positive / 1=negative) Indicates the moving direction of the 3rd axis (0=Positive / 1=negative) Indicates the moving direction of the Z axis (0=Positive / 1=negative) Indicates the moving direction of the 4th axis (0=Positive / 1=negative) 1.2 OUTPUTS 1.2.1 ENABLING THE CYCLE-START KEY VIA PLCI With this feature it is possible to set the treatment of the [CYCLE START] of the CNC via PLCI. Machine parameter "P621(7)" indicates whether this feature is available or not. P621(7) = 0 P621(7) = 1 This feature is not available. This feature is available. When using this feature, the way the CNC handles the [CYCLE START] key depends on the status of PLCI output O25 (CYCLE START ENABLE). O25 = 0 O25 = 1 signal. The CNC ignores both the [CYCLE-START] key and the external [CYCLE-START] signal. The CNC takes into account both the [CYCLE-START] key and the external [CYCLE-START] 1.2.2 TRAVEL LIMITS SET VIA PLCI With this feature, the travel limits of the axes may be set via PLCI. Machine parameter "P621(7)" indicates whether this feature is available or not. P621(7) = 0 This feature is not available. P621(7) = 1 This feature is available. To set the travel limits for each axis, use the following outputs: O52 / O53 Positive / negative X axis limits O54 / O55 Positive / negative 3rd axis limits O56 / O57 Positive / negative Z axis limits O58 / O59 Positive / negative 4th axis limits When the PLCI activates one of this outputs while the axis is moving in the same direction, the CNC stops the axes and the spindle and it displays an axis-travel-limit-overrun error. -3- 1.2.3 DENYING ACCESS TO THE EDITOR MODE VIA PLCI Machine parameter"P621(7)" indicates whether this feature is available or not. P621(7) = 0 This feature is not available. P621(7) = 1 This feature is available. When using this feature, access to the editor mode at the CNC depends on the status of PLCI output O26, as well as on the current conditions (protected memory, number of the program to be locked). O26 = 0 Free access to the editor mode (it is protected by current conditions). O26 = 1 Denied access to the editor mode. 1.2.4 SPINDLE CONTROLLED VIA CNC OR VIA PLCI From this version on, the spindle analog output may be set either by the CNC or by the PLCI. Machine parameter "P621(7)" indicates whether this feature is available or not. P621(7) = 0 P621(7) = 1 This feature is not available This feature is available Setting the spindle analog output via PLCI To do this, use the combination: M1956 - R156. Register R156 sets the spindle analog output in units of 2.442 mV. (10 / 4095) R156 = 0000 1111 R156 = 0001 1111 R156 = 0000 0000 R156 = 0001 0000 1111 1111 1111 1111 0000 0001 0000 0001 (R1256=4095) = 10V. = -10V. (R1256=1) = 2.5 mV. = -2.5 mV. In order for the CNC to assume the value allocated to register R156, one must activate mark M1956 as described in the PLCI Manual (section 5.5.2. Writing internal CNC variables). Spindle controlled either by the CNC or by the PLCI The CNC may have two internal spindle analog outputs, that of the CNC itself and the one set by the PLCI. Use PLCI output O27 to "tell" the CNC which one of them to output. O27 = 0 O27 = 1 Spindle analog output set by the CNC itself. Spindle analog output set by the PLCI (combination: M1956-R156). 1.3 READING INTERNAL CNC VARIABLES From this version on, the PLCI and the PLC64 have access to more internal CNC information. With the PLCI, there is no need to activate a mark to access this information. The CNC itself updates this information at the beginning of each PLCI cycle scan. With the PLC 64, the corresponding mark must be consulted every time a CNC variable is to be checked. The CNC information now accessible is: Real S in rpm (REG119 at the PLCI, M1919 at the PLC64) Not to be mistaken with R112 which indicates the programmed Spindle speed (S). It is given in rpm and in hexadecimal format. Example: S 2487 R119= 967 Number of the block in execution (REG120 at the PLCI, M1920 at the PLC64) It is given in hexadecimal format. Example: N120 R120= 78 Code of the last key pressed (B0-7 REG121 at the PLCI, Not available at the PLC64) Not to be mistaken with register R118 which also indicates the code corresponding to the last key pressed, but-- When pressing a key, both registers have the same value; but data in R121 is only kept there for one cycle the scan whereas R118 keeps its value until another key is pressed . When pressing the same key several times, (for example: 1111): R121 will show code "1" four times (once per cycle scan). R118 will always show the same value, thus not being able to tell whether the "1" key has been pressed once or more times. The key codes are listed in the appendix of the PLCI manual. -4- Operating mode selected at the CNC (B8-11 REG121 at the PLCI, Not available at the PLC64) B8 0 0 0 0 0 0 0 0 1 1 B9 0 0 0 0 1 1 1 1 0 0 B10 0 0 1 1 0 0 1 1 0 0 B11 0 1 0 1 0 1 0 1 0 1 Automatic Single block Play-Back Teach-in Dry-Run JOG Editor Peripherals Tool Table and G functions Special modes Not available at the PLC64) Status of the miscellaneous "M" functions (REG122 at the PLCI, The status of each one of these functions is given by a bit and will appear as a "1" when active and "0" when inactive.

SPINDLE SPEED DISPLA UNITS Until now, the spindle speed was always displayed in rpm. From now on, the display units may be selected by means of machine parameter "P621(6)". P621(6) = 0 P621(6) = 1 In rpm when operating in RPM and in m/min. (ft./min.) when at Constant Surface Speed. Always in rpm, even when operating at Constant Surface Speed. 4. SINGLE BLOCK TREATMENT The CNC considers a "Single block" the group of blocks between a G47 and a G48. After executing function G47, the CNC executes all the following blocks until executing a block containing function G48 even when in Single Block mode . If is pressed while executing a "single block" in Automatic or Single-Block mode, the CNC keeps executing the rest of the blocks until it runs into a G48 and it, then, interrupts program execution. While function G47 is active, the Manual Feedrate Override switch and the spindle speed override keys will be disabled, thus the program will be executed at 100% of the programmed F and S values. Functions G47 and G48 are modal and incompatible with each other. On power-up, after executing an M02/M30, after an EMERGENCY or a RESET, the CNC assumes G48. 5. TWO ELECTRONIC HANDWHEELS ARE NOW POSSIBLE From this version on, up 2 electronic handwheels may be used one for the X axis and another one for the Z axis. The 4th axis and the Live Tool will no longer be available. The feedback inputs will be used as follows: A1 - X axis; A2 - Z axis handwheel; A3 - Z axis; A4 - 3rd axis or "C" axis; A5 - Spindle; A6 - X axis handwheel The handwheels will be operative when selecting the JOG mode. One of the handwheel positions must also be selected at the Manual Feedrate Override switch of the operator panel. The possible positions are: 1, 10 and 100, which indicate the multiplying factor applied to the pulses coming from the electronic handwheel. -5- This way and after applying the multiplying factor, one obtains the axis moving units. These units correspond to the units used for the display format Example: Handwheel Resolution : 250 lines per turn MFO Switch position 1 10 100 Distance per turn 0.250 mm or 0.0250 inch 2.500 mm or 0.2500 inch 25.000 mm or 2.5000 inches When attempting to "crank" an axis faster than its maximum feedrate (machine parameters "P110, P310"), the CNC will limit the actual axis feedrate to that parameter value ignoring the rest of the pulses supplied by the handwheel, thus preventing a Following Error message from being issued. 5.1 MACHINE PARAMETERS FOR THE HANDWHEELS: P622(6) = 0 P622(6) = 1 P609(1) = 0 P609(1) = 1 There is no electronic handwheel associated with the Z axis There is electronic handwheel associated with the Z axis The electronic handwheel being usedis not a FAGOR 100P model. The electronic handwheel being usedis a FAGOR 100P model. This parameter makes sense when using a single handwheel associated with the X axis. It indicates whether or not it is a FAGOR 100P with axis selector button.
