(July 1996) EXPANSION OF THE INTEGRATED PLC RESOURCES 1.1 INPUTS 1.1.1 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 Y axis is being homed (0=No / 1=Yes) Indicates whether the Z axis is being homed (0=No / 1=Yes) Indicates whether the W axis is being homed (0=No / 1=Yes) Indicates whether the V axis is being homed (0=No / 1=Yes) 1.1.2 AXIS MOVING DIRECTION Inputs I42, I43, I44, I45 and I46 will show, at all times, the moving direction of each axis. I42 I43 I44 I45 I46 Indicates the moving direction of the X axis (0=Positive / 1=negative) Indicates the moving direction of the Y axis (0=Positive / 1=negative) Indicates the moving direction of the Z axis (0=Positive / 1=negative) Indicates the moving direction of the W axis (0=Positive / 1=negative) Indicates the moving direction of the V axis (0=Positive / 1=negative) 1.2 1.2.1 OUTPUTS 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 "P627(7)" indicates whether this feature is available or not. P627(7) = 0This feature is not available. P627(7) = 1This 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 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] signal. 1.2.2 TRAVEL LIMITS SET VIA PLCI With this feature, the travel limits of the axes may be set via PLCI. Machine parameter "P627(7)" indicates whether this feature is available or not. P627(7) = 0This feature is not available. P627(7) = 1This feature is available. To set the travel limits for each axis, use the following outputs: O52 / O53 O54 / O55 O56 / O57 O58 / O59 O60 / O61 Positive / negative X axis limits Positive / negative Y axis limits Positive / negative Z axis limits Positive / negative W axis limits Positive / negative V 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 P627(7) = 0This feature is not available. P627(7) = 1This feature is available. Machine parameter "P627(7)" indicates whether this feature is available or not. 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 O26 = 1 Free access to the editor mode (it is protected by current conditions). 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 "P627(7)" indicates whether this feature is available or not. P627(7) = 0This feature is not available P627(7) = 1This 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 1111 1111 R156 = 0001 1111 1111 1111 R156 = 0000 0000 0000 0001 R156 = 0001 0000 0000 0001 (R1256=4095) (R1256=1) = 10V. = -10V. = 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, butWhen 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 Status of the miscellaneous "M" functions (REG122 at the PLCI, Not available at the PLC64) 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.

This feature is available on the following models: CNC-8025M CNC-8025MI CNC-8025MG CNC-8025MGI CNC-8025MS CNC-8025MSI Machine parameter "P627(6)" indicates whether this feature is available or not. P627(6) = 0 P627(6) = 1 This feature is not available This feature is available This function may be selected by the operator. To do this, activate: On models without PLCI: On modelswith PLCI: Operation: As the CNC executes motion blocks, it always stores the last 10 blocks already executed Whenever it executes a block containing an M,S,T type function, the machining conditions change and the CNC deletes those previously stored motion blocks. When the retrace function is activated, the block currently in execution is interrupted and the retrace process begins. First to the starting point of the current block and, then, to that of the previously stored program blocks. If all the stored blocks are executed, the CNC stops the machine until the retrace function is canceled. When this function is canceled, the CNC interrupts the current movement (if any) and it executes all the retraced blocks again. Once the interruption point is reached, the CNC resumes the execution of the program. pin 7 of connector A5. PLCI output O47 3. OPERATION WITH TWO MOTORS AND 3 AXES. Machine parameter "P627(8)" indicates whether this feature is available or not. P627(8) = 0This feature is not available. P627(8) = 1This feature is available. Operation: The CNC permits using 2 motors to move 3 axes with the following conditions: One of the axes shared by a motor must be the Z axis and the other one must be either the X or the Y axis. Only interpolations between the X and Y axes are possible. The Z axis cannot be interpolated with any other axis. It must be moved alone. Example: To move the tool from "X0 Y0 Z0" to "X20 Y20 Z20", The CNC will make this move in two steps. First, it will move the X and Y axes to X20 Y20 and, then, the Z axis to Z20. -5- 4. SPINDLE FOLLOWING ERROR DISPLAY WHILE IN M19 From this version on, when operating with spindle orient (M19), the CNC also shows the spindle following error on the screen corresponding to the following error in Automatic and Single block modes. The Following Error screen shows, in large characters, the amount of axis lag and, under it, the following information line. F 00000.0000 & 100 S 0000 % 100 T 00.00 S 0000.000 The last value of this line"S 0000.000" shows the amount of following error (lag) of the spindle when it operates in spindle orient mode (M19). 5. GANTRY AXES NOT MECHANICALLY SLAVED From this version on, depending on the setting of machine parameter "P629(8)", it is possible to work with two different types of Gantry axes. "P629(8)=0" Mechanically slaved Gantry Axes. As until now. When being homed, both axes behave as a single axis. The CNC takes into account only the parameter settings and feedback pulses of the main axis, the slaved one being just a follower of the main axis, Not-mechanically slaved Gantry axes. When being homed, the two axes behave as separate independent axes. First the main axis is homed and, then, the slaved one. "P629(8)=1" 6. SHEETMETAL FORMING MACHINES This feature is available on GP models. To enable it, set machine parameter "P626(7)=1". The CNC enables functions M98 and M99 to control the X axis positioning loop. Function M98 opens the X axis loop and M99 closes it. When the CNC executes an M30, it also closes the X axis positioning loop. When operating in jog mode, the CNC enables he following keys to control the X axis positioning loop: Executes an M98 opening the X axis loop. Executes an M98 opening the X axis loop. Executes an M98 closing the X axis loop. Version 7.2 1. SCREEN SAVER The screen saver function works as follows: (April 1997) After 5 minutes without pressing a key or without the CNC refreshing the screen, the screen goes blank. Press any key to restore the display. Machine parameter "P626(5)" indicates whether this feature is to be used or not. P626(5) = 0This feature is not being used. P626(5) = 1This feature is being used. 2. JOGGING FEEDRATE If while in JOG mode, the conditional input (block skip), pin 18 of connector I/O1, the CNC does not allow entering a new F value. Only the feedrate override (%) may be varied by means of the MFO switch. -6- 3. PARAMETRIC PROGRAMMING NEW FUNCTION: F34 . Function F34 returns the number of the tool being dealt with. P27=F34 Parameter P27 takes the value of the new tool being dealt with. This function must be used when working with a subroutine associated with the tool change. When using it outside that subroutine, function F34 returns the value of "100". Version 7.3 1. PLCI. Input I87 While the CNC is threading (G84), PLCI input I87 is set to "1". Note: Input I97 indicates rigid tapping. (March 1998) Version 7.4 (May 1999) 1. NEW MACHINE PARAMETER ASSOCIATED WITH THE M FUNC ...
