Page 3: Dro Description
There are 20 tools that may be set for the part when using absolute coordinates. The possible reference points (datum points) are from 0 to 19. The 20i-T model shows the active reference on the display at all times, whereas the 30i-T model only shows it when it is selected, after pressing the reference key. -
Page 4: Turning The Unit On And Off
1.2 Turning the unit on and off It turns on automatically when applying voltage or after pressing the on/off key. It shows Fagor dro or the corresponding error code. See the error table and PAR11 for more options. Turns the DRO on or off. -
Page 5: Dro Operation
The third axis (Zs) display shows the feedrate of the fastest moving axis in m/min or feet/min depending on the status of the "inch" LED. To activate or cancel this option, see PAR11 in the installation manual. V0612 - 20i-T / 30i-T - Installation/Operation - DRO operation - (5/32) -
Page 6: Incremental, Absolute And With Respect To Machine Reference Zero
2.2 Incremental, absolute and with respect to Machine Reference Zero This DRO shows the current position of two or three axes (20i-T / 30i-T). Coordinate means the distance from one point or position with respect with another chosen as reference. -
Page 7: Example
This last method turns out to be more practical as after selecting the destination coordinate one only has to remember to move the axis until the DRO reads zero.
