2.4.2.3 Setting part zero (datum) without using the assistant Change Reference Set a datum point at a corner other than the 3rd quadrant. Compensate for tool radius on the X axis. Touch with the tool on the side indicated in the figure. Set the X axis to zero.
2.5 Special functions Function It gives access to the specific milling functions. 2.5.1 Cycles The DRO allows storing 99 cycles, numbered from 1 to 99. The cycles may be executed, deleted or edited at will. The screen shows the data of the selected cycle so it can be identified easily.
2.5.1.2 Linear drilling Function Linear drilling It allows up to 99 holes to be drilled in line in different planes (XY, XZ, YZ) without having to calculate the coordinates (X Y) of each hole, by simply keying in some basic data. Select Plane.
2.5.2 Programs Various cycles may be joined one after another making a program. The programs may be executed, deleted or edited at will. Cycle number 0 indicates the end of the program. Deletes the selected cycle. Inserts an empty cycle in the current position. Executes the current program.
2.5.3 Calculator function Function Calculator It may be used to carry out mathematical and trigonometric operations as well as preset the desired axis with the result of the calculation or import the displayed coordinate values into the calculator to carry out math operations. Different types of calculators may be selected at the function bar: Arithmetic, trigonometric and for square functions.
2.5.4.2 Cycle execution Pressing the Run key, the DRO shows the distance the axes must move to position at the first hole. Move the axes to zero. The status bar indicates the number of the current hole and the total number of holes programmed in the cycle.
The probe stores the data about the probed points in a USB memory. The probing data may be read and processed at a PC. The file containing the probed points is: FAGOR/DRO/PROBE/probe.csv The format of the generated file is “csv” (comma separated values) and may be easily imported into a spreadsheet.
3 DRO installation There are two ways to mount the DRO 400i P: 1- Mounted on the support arm. 2- Built-in model. 3.1 Mounting on the support arm The DRO may be mounted at the desired height and may be oriented at will.
3.3 Dimensions of the display, the bracket and of the window to insert it into The first figure shows the DRO dimensions. The second figure shows the dimensions of the hole needed in the enclosure of the machine to built this model into. The dimensions of the bracket where the arm is mounted are shown in the third figure.
3.4 Rear panel On the back of the unit the following items may be found: • Three-prong power connector for AC and ground connection. • On/off switch. • M6 mm terminal, for general machine ground connection. • Mounting bracket • USB connector.
3.5 General technical characteristics - Universal Power Supply between 100V AC and 240V AC ±10% at a mains frequency between 50 Hz and 60 Hz, between 140 V DC and 340 V DC. Maximum power consumed 25 VA. It withstands power outages of up to 10 milliseconds.
3.6 Connections 3.6.1 Connection of the feedback systems The feedback systems (linear or rotary encoders) are connected via SUB-D HD type 15-pin female connectors: X1 through X4. Characteristics of feedback inputs: X1, X2, X3 and X4: -Maximum feedback consumption: 250 mA at the +5V input. -Admits square-wave signal (TTL).
3.6.2 Probe connection (connector X6) Either a 5 V or a 24 V probe may be connected. Characteristics of probe inputs X6: 5V probe input Typical value 0,25 mA. Vin = 5 V. High threshold (logic level "1") VIH: From +2.4 V DC on. Low threshold (logic level "0") VIL: Below +0.9 V DC.
Interface with an open-collector output. Connection to +5 V. Acts with a down flank. Interface with an open-collector output. Connection to +24 V. Acts with a down flank. Interface with a PUSH-PULL output The active flank depends on the interface used 3.6.3 Power and machine connection Always mount it vertically so its keyboard is within operator's reach and its digits are easily visible (at...

3.7.3.2 DRO Setup Configuration Install It configures the DRO for each type of machine: Number of axes, type of machine (mill, lathe, etc.). Pressing this button opens the window shown on DRO Parameters the right. The following items are set in it: Type of Machine Lathe 1- Type of Machine: Mill or lathe.
Setup Configuration Install Feedback FAGOR Selecting Fagor feedback knowing the name or model of the linear encoder. Select axis. Select type of linear encoder, type of signal and type of reference pulse. To validate the data for that axis. 400i P - Installation / Operation - (29/36)

1Vpp or TTL with distance-coded reference marks. Example: We wish to install a FAGOR GP linear encoder (1 Vpp and 20-micron-pitch graduated glass) with 1 micron resolution: Graduation pitch (20, 40 or 100 µm)
Reference Setup Configuration Install Feedback Reference This window sets the parameters related to home search and the type of reference mark of the encoder. This configuration must be set for each axis. * User offset: Offset of the reference point with respect to the reference zero of the feedback device, independent for each axis.
Important: Before capturing data for an accuracy graph, a home search must be carried out because the compensation will not be applied until the home search is done. To use this compensation, it is recommended to force a home search on power-up.
The DRO must not be powered-on until verifying that the machine complies with the "2006/42/EC" Directive. 4.2.1 Declaration of conformity The declaration of conformity for the DRO is available in the downloads section of FAGOR’S corporate website at http://www.fagorautomation.com. (Type of file: Declaration of conformity). 4.2.2 Safety conditions Read the following safety measures in order to prevent harming people or damage to this product and those products connected to it.

Do not work in explosive environments. In order to avoid risks, harm or damages, do not work in explosive environments. Working environment. This unit is ready to be used in Industrial Environments complying with the directives and regulations effective in the European Community. It is recommended to mount the DRO vertically, so its power switch of the back panel is at a distance between 0.7m (27.5 inches) and 1.7m (5.6 ft) off the floor and away from coolants, chemical products, blows etc that could damage it.
The cardboard being used to make the box must have a resistance of 170 Kg (375 lb.). When sending it to a Fagor Automation office for repair, attach a label indicating the owner of the unit, person to contact, type of unit, serial number, symptom and a brief description of the problem.
