Page 3: Preliminary Remarks
USER MANUAL DIGITAL READOUT VISION 518 PRELIMINARY REMARKS GIVI MISURE would like to thank you for purchasing the programmable digital readout MICROCOMPUTER and confirms the excellent choice made. Thanks to a powerful microcontroller, the instrument is completely programmable by keyboard. This means that VISION can be optimized with a number of specific functions for any type of machine tool. -

Page 8: Data And Programs Retention
USER MANUAL DIGITAL READOUT VISION 518 DATA AND PROGRAMS RETENTION When the mains power supply is disconnected, the instrument can retain in its memory all the data and programs set. When powered off, the instrument can also store the last axis counting position. -
Page 9: Standard Functions
USER MANUAL DIGITAL READOUT VISION 518 STANDARD FUNCTIONS SELECTING A STANDARD FUNCTION To recall a function, press the F key, use the +/- key to select the code of the desired function and confirm it with EXE. At any time, it is possible to quit the operation by pressing the CLR key. -
Page 10: Self-Testing
USER MANUAL DIGITAL READOUT VISION 518 Example: r E F Press The display flashes and requires the operator to perform the zero reference (REF) search. With this function, it is possible to set the 0 value in correspondence to the zero reference position. -
Page 11: Absolute/Incremental Counting
USER MANUAL DIGITAL READOUT VISION 518 ABSOLUTE/INCREMENTAL COUNTING The point positioned on the right of the display indicates the counting mode set. More specifically, if the point is TURNED ON = AXIS IN ABSOLUTE COUNTING MODE (ABS) TURNED OFF = AXIS IN INCREMENTAL COUNTING MODE (INC) To switch the axis from one counting mode to the other, press the ABS key;... -

USER MANUAL DIGITAL READOUT VISION 518 Note. During the position preset, the following keys can be used: - 0 0 0 5 0 . 0 0 to set a negative value to quit the preset operation and maintain the previous position set. -
Page 16: Counting Modef
USER MANUAL DIGITAL READOUT VISION 518 COUNTING MODE F 25 This function allows to select the counting mode of the A and B channels of the encoder. The counting mode can be direct, double, quadruple or mono-directional. C n t Press The display will show the direct counting mode (n1). -
Page 17: Linear Correction F
USER MANUAL DIGITAL READOUT VISION 518 LINEAR CORRECTION F 30 Machining errors can derive from geometrical defects of the machine due to wear, lack of linearity of the guides, coupling clearances between carriage and guide, badly distributed weights, etc. If these errors are linear, i.e. proportional to the movement executed, they can be compensated with the linear correction function. -
Page 18: Radius/Diameter Conversion F
USER MANUAL DIGITAL READOUT VISION 518 The linear correction has the following characteristics: 1. it is permanently stored (it becomes a mechanical component of the axis); 2. it can always be modified, entering other CF values. The permitted values are: = 0.000001... -
Page 19: Variable Resolution F
USER MANUAL DIGITAL READOUT VISION 518 VARIABLE RESOLUTION F 36 The instrument shows on the display the resolution initially programmed by the Manufacturer (this corresponds to the resolution of the measuring system). If machining can be facilitated by a lower resolution (e.g. roughing machining), the operator can decrease it. -
Page 20: Angular Readingf
USER MANUAL DIGITAL READOUT VISION 518 ANGULAR READING F 38 On request, the instrument can be configured by the Manufacturer to operate in angular reading, in order to be used with a rotary encoder. The resolution depends on the number of encoder pulses (PPR). -
Page 21: Relay Outputs Activation F
USER MANUAL DIGITAL READOUT VISION 518 RELAY OUTPUTS ACTIVATION F 40 With this function, it is possible to set the intervention of two relays during machining. This will occur in correspondence of some positions set during programming (see function F 42). When reaching the positions, the relays (if enabled) switch their status, opening or closing a contact. - Page 22 USER MANUAL DIGITAL READOUT VISION 518 SETTING TIMED RELAY OUTPUTS F 41 With this function it is possible to set the duration of the intervention of two relays at the programmed positions (see function F 42). Let us suppose that, in their rest condition, relay 1 has been set with the NC status (normally closed) and relay 2 has been set with NO status (normally open).
- Page 23 USER MANUAL DIGITAL READOUT VISION 518 Axis in linear reading: NO = a timed intervention is generated when the position passes from a value lower than the intervention position, to a higher or equal value. NC = a timed intervention is generated when the position passes from a value higher or equal to the intervention position, to a lower value.
- Page 24 USER MANUAL DIGITAL READOUT VISION 518 The program has been completed and, in our example, the two relays act like measuring length limits. In fact, relay 1 closes its contact if the position is lower than 150.00; relay 2, instead, closes its contact if the position is higher or equal to 300.00.
- Page 25 USER MANUAL DIGITAL READOUT VISION 518 Examples of programming with the axis in linear reading: NO = normally open NC = normally closed Example 1: Relay 1 NO at the position +100, Relay 2 NC at the position -100 RELAY 2...
