SUGGESTIONS FOR THE RS-232C INTERFACE * Cable length The EIA RS232C standard specifies that the cable capacitance must not exceed 2500pF; therefore, since a typical cable for this application usually has a capacitance from 130 to 170pF/m, the maximum length will be limited to 15m (50 ft). It is recommended to use shielded twisted-pair cables in order to minimize interference thus avoiding poor communications over great lengths. It is recommended to use 7-conductor cables with a minimum section of 0.14 mm² per conductor and overall shield.
Atention: Do not manipulate the connectors with the unit connected to main AC power Before manipulating these connectors (inputs/outputs, feedbach, etc) make sure that the unit is not connected to main AC power

CONSIDERATIONS FOR THE RS-422 INTERFACE It uses two separate cables for each signal. This presents the following advantages: - It increases noise immunity. - It allows data transmission over greater distance for the same baudrate. - It reduces problems due to different ground potentials and interference between signals. The RS422 standard does not define the communications protocol to be used. It can be used together with the RS499 standard. A line terminating resistor must be installed between pins 3 and 8 (transmit data) as well as between pins 4 and 5 (receive data). These resistors must be placed at both connectors and its value must match the characteristic impedance of the cable. Typical value : 120 Ohms 1/4W.
Atention: Do not manipulate the connectors with the unit connected to main AC power Before manipulating these connectors (inputs/outputs, feedbach, etc) make sure that the unit is not connected to main AC power

CONNECTION TO THE CNC
2.2.1 GENERAL CONSIDERATIONS The machine tool must have decoupled all those elements capable of generating interference (relay coils, contactors, motors, etc.). * D.C. relay coils. Diode type 1N4000 * A.C. relay coils. RC connected as close as possible to the coils. Their approximate values should be: R220 Ohms/1w. C 0,2µF/600V. * A.C. motors.
RC connected between phases with values:
R 300 Ohms/6W C 0,47µF/600V. Ground connection. It is imperative to carry out a proper ground connection in order to achieve: * Protection of anybody against electrical shocks caused by a malfunction. * Protection of the electronic equipment against interference generated by the proper machine or by other electronic equipment near by which could cause erratic equipment behavior. Therefore, it is crucial to install one or two ground points where the above mentioned elements must be connected. Use large section cables for this purpose in order to obtain low impedance and efficiently avoid any interference. This way, all parts of the installation will have the same voltage reference. Even when a proper ground connection reduces the effects of electrical interference (noise), the signal cables require additional protection. This is generally achieved by using twisted-pair cables which are also covered with anti-static shielding mesh-wire. This shield must be connected to a specific point avoiding ground loops that could cause undesired effects. This connection is usually done at one of the CNC’s ground points. Each element of the machine-tool/CNC interface must be connected to ground via the established main points. These points will be conveniently set close to the machinetool and properly connected to the general ground (of the building). When a second point is necessary, it is recommended to join both points with a cable whose section is no smaller than 8 mm2 (or 2 cables of 4 mm2).

OPERATION WITH 8010/20/25/30 CNC
This operating mode is designed to work with the 8010, 8020, 8025 and 8030 family CNCs. The possible functions from the CNC are the following: -
Directory request Send a program Receive a program Delete a program Format the floppy disk to 720Kb (double density) or 1.44Mb (high density).
Atention: With the current CNC version it is not possible to format diskettes. Therefore, they must be formatted at a PC or purchased previously formatted. In order to operate at the baudrates indicated in the configuration table, it is necessary to set the following parameters at the CNCs: 8010 MILL 8010 LATHE
P101 (BIT 4) = 1 P99 (BIT 6) = 1
8020 MILL 8020 LATHE 8020 PUNCH
P121 (BIT 4) = 1 P99 (BIT 6) = 1 P121 (BIT 4) = 1

3.2 GENERAL CONSIDERATIONS FOR OPERATION WITH THE CNC. Considerations regarding CNC format. * The display format of the CNC cannot show numbers greater than 99999; therefore, this amount will appear whenever the free memory space on the disk exceeds this value. * When aborting the transmission of a program from the CNC to the floppy unit, wait for 10 sec. before requesting another operation. Compatibility with programs edited at a PC. * The disk being used may have programs generated at the FAGOR CNC or edited at a PC. The programs edited at a PC must meet the following conditions: 1.- The text editor must be an ASCII editor. 2.- The program name must consist of five digits (0-9), a period and one of these three extensions: - PIM for mill part-programs. - PIT for lathe part-programs. - PIP for punch part-programs. This type of names will indicate that the program has been edited at a PC. 3.- It is not possible to delete programs edited at a PC from the CNC. 4.- Each line of a program edited at a PC must only have one complete block. 5.- When a disk has two programs with the same name but one in CNC format (without extension) and the other one in PC format (with extension), the CNC will work with the one in CNC format by default. 6.- When getting a disk directory, the programs with the same name will appear in the following order: 1st, those with CNC format (without extension). 2nd, those with PC format (with extension .PIM). 3rd, those with PC format (with extension .PIT). 4th, those with PC format (with extension .PIP).

PROTOCOL (P4) Indicates the type of communication protocol used to transmit characters. 0 = Communication protocol for general peripheral device. 1 = DNC protocol. 2 = FLOPPY DISK UNIT. When working with the FLOPPY DISK UNIT, this parameter must be set to 2. PWONDNC (P5) Indicates whether the DNC function is active or not on CNC power-up. NO = Not active on power-up. YES = Active on power-up. When working with the FLOPPY DISK UNIT, this parameter must be set to YES. DNCDEBUG (P6) Indicates whether the CNC aborts DNC communications after an internally set period of time without establishing communication. It is recommended to use this safety function in every DNC communications process and to do without it while debugging. NO = It is not in debugging mode and it does abort communications. YES = It is in debugging mode and it does NOT abort communications. The floppy disk unit has no debugging mode.

4.4 CNC FEATURES. Once the FLOPPY DISK UNIT is on and while active, it is possible to perform the following operations from the CNC. * Save a CNC program in the FLOPPY DISK UNIT. * Load a program from the FLOPPY DISK UNIT into the CNC. * Delete a program contained in the FLOPPY DISK UNIT. * Display the program directory of the FLOPPY DISK UNIT on the CNC screen. * Save one of the CNC tables in the FLOPPY DISK UNIT. * Load one of the CNC tables from the FLOPPY DISK UNIT. * Save a user page or symbol of the CNC into the FLOPPY DISK UNIT. * Load a user page or symbol of the CNC from the FLOPPY DISK UNIT. * Generate in the FLOPPY DISK UNIT the program resulting from a digitizing operation. This function is available on the Mill model CNC being necessary to set the OPEN statement at the CNC so the resulting program is stored at the FLOPPY DISK UNIT. When the generated program takes more than 1 floppy disk, it is referred to as "Multi-volume Digitizing". The CNC will request the change of disk. The "Multi-volume Digitizing" feature is available from version 2.1 on and from 8050M CNC version 9.01 on. * Execute or simulate at the CNC an infinite program contained in the FLOPPY DISK UNIT. Once the execution or simulation mode has been selected at the CNC, press the softkey corresponding to the serial line to be used for the data transmission. The CNC will display the program directory of the floppy disk unit and after selecting one of them, operate as with any CNC program. When the program to be executed or simulated takes more than 1 floppy disk, it is referred to as "Multi-volume Infinite". The CNC will request the change of disk. The "Multi-volume Infinite" feature is available from version 2.1 on and from 8050M CNC version 9.01 on. * Format floppy disks to 720Kb (Double density) or 1.44Mb (high density).

APPENDIX I MAINTENANCE
Cleaning: The accumulated dirt inside the unit may act as a screen preventing the proper dissipation of the heat generated by the internal circuitry which could result in a harmful overheating of the floppy disk unit and, consequently, possible malfunctions. On the other hand, accumulated dirt can sometimes act as an electrical conductor and shortcircuit the internal circuitry, especially under high humidity conditions. To clean the operator panel and the monitor, a smooth cloth should be used which has been dipped into de-ionized water and /or non abrasive dish-washer soap (liquid, never powder) or 75º alcohol. Do not use highly compressed air to clean the unit because it could generate electrostatic discharges. The plastics used on the front panel of the floppy disk unit are resistant to : 1.- Grease and mineral oils 2.- Bases and bleach 3.- Dissolved detergents 4.- Alcohol
Avoid the action of solvents such as Chlorine hydrocarbons , Benzole , Esters and Ether which can damage the plastics used to make the unit’s front panel.
Preventive Inspection: If the floppy disk does not turn on when actuating the start-up switch, verify that the fuses are in good condition and that they are the right ones. It has two 2Amp./250V fast fuses (F),one per AC mains line.

To check the fuses, first disconnect the power to the CNC. Do not manipulate inside this unit. Only personnel authorized by Fagor Automation may manipulate inside this module. Do not manipulate the connectors with the unit connected to main AC power. Before manipulating these connectors, make sure that the unit is not connected to main AC power. Note : Fagor Automation shall not be held responsible for any material or physical damage derived from the violation of these basic safety requirements.
