Wiring diagram — index and first findings¶
Built 31 Aug 2026 from the OCR text layer of the diagram in Google Drive. No page was viewed as an image, so everything here is OCR-derived and marked for confidence. Treat it as a lookup aid that says which sheet to open, not as a substitute for reading the sheet.

Provenance of the diagram¶
Drawn by TEA S.A. (Titan Electronics Automation) for Masterwood. Project TIDW0006, internal code COBIDW0006, order 4190 dated 16/04/02, drawn 18/04/02 by "F.S.". Machine model IDW280, supply 400 V 50 Hz, current draw 60.3 A.
⚠️ Page numbers from the OCR proved unreliable - several were wrong by a wide margin (AUX INSERITI was listed at 40, it is 11; CIRCUITO AUX was listed at 14-15, it is 12). Trust sheet titles, and only trust a page number once the sheet itself has been seen.
✅ Resolved 2 Sep 2026: both figures were right, measuring different things. The cover sheet's REVISIONE FOGLI table shows a Q.E. section of 40 schematic sheets, plus SGM and DISTINTA sections, and the device-list pages are numbered "Pag. n ... 14 Pg." So the PDF holds roughly 55-66 pages of which the schematics are 40. Use "40 Q.E. schematic sheets plus a 14-page device list".

The SGM section - 12 pages of connector schedules¶
Found 2 Sep 2026. A third section of the document, separate from the Q.E. schematics and the device list: a pin-by-pin schedule for every connector, giving source terminal, wire number, colour, cross-section and destination terminal. Pages 1-5 read; see connector-schedules.md.
| SGM page | Connector |
|---|---|
| 1 | =Q.E.-A, Harting 32-pole to =BM+X3 |
| 2 | =Q.E.-B, Harting 16-pole to =BM+X43 |
| 3 | =Q.E.-C, Harting 32-pole to =BM+X4 and +X5 |
| 4 | =Q.E.-D, Harting 32-pole to =BM+X5 |
| 5 | =Q.E.-S, the spindle 15-pin - pins 8 (WH) and 15 (BN) only, to -R6:1 and -R6:4 |
| 6 | =Q.E.-X, the X axis 15-pin - the definitive encoder colour map |
| 7 | =Q.E.-Y |
| 8 | =Q.E.-Z |
| 9 | =BM+X5-V1, the 25-pin valve connector |
| 10 | CONNETTORE ELETTROMANDRINO HSD (M200) - the spindle index and drawbar sensors |
| 11 | COLLEGAMENTI SERIALI - overview of the four serial cables |
| 12 | COLLEGAMENTI SERIALI - the cable pinouts. See serial-port.md |
✅ The whole document is now read: 40 Q.E. sheets, 13 device-list pages, 12 SGM connector schedules.
✅ COLLEGAMENTI SERIALI found: SGM pages 11 and 12. It is not in the Q.E. section at all, which is why the OCR page number was meaningless - it came from a different section's numbering.
| 16-21 | INPUT IF1-IF6 | The six input modules, one sheet each. 16-20 read; see io-map.md. Sheet 21 (IF6, EIN41-48) still outstanding |
| 23–28 | OUTPUT UF1–UF6 | The six output modules, one sheet each |
| 22 | F.C. O ASSI | 🔴 The axis zero/home switches BOX, BOY, BOZ, returning to the axis card on pin 6 of each axis D-sub. See io-map.md |
| 23-28 | OUTPUT UF1-UF6 | The six output modules, one sheet each. All read; see io-map.md |
| 29 | ENCODER ASSE X | X motor encoder, connector 2CN.X. Four conductors plus shield, serial |
| 30 | ENCODER ASSE Z ⚠️ | Title block is wrong. The drawing is AXIS Y DRIVER CONNECTOR, components -ENC.Y / -2CN.Y / =BM+X4. It is the Y axis |
| 31 | ENCODER ASSE Y ⚠️ | Title block is wrong. The drawing is AXIS Z DRIVER CONNECTOR, -ENC.Z / -2CN.Z / =BM+X5. It is the Z axis. Sheets 30 and 31 are swapped |
| 32 | ENCODER ASSE 560 | The carousel encoder: full differential quadrature plus RX//RX, 12 conductors, on -SIG2. Header says ASSE 561 |
| 32 | ENCODER ASSE 560 | Carousel/ATC axis encoder (Panasonic MSS083A1XP 750 W) |
✅ Pinned 2 Sep 2026, from the sheets themselves: AZION. ASSE X = page 7, ASSE Y = page 8, ASSE Z = page 9, ASSE 560 (Panasonic) = page 10. SGDH-15DE on X, SGDH-10DE on Y and Z. Read up in servo-drive-interface.md.
Finding 1 — the module numbering is confirmed, not just arithmetic¶
The diagram's own cross-references resolve it. Signals carry page.line references, and they fall out as:
| Module | Sheet | Signals |
|---|---|---|
| IF1 | 16 | EIN1–EIN8 |
| IF2 | 17 | EIN9–EIN16 |
| IF3 | 18 | EIN17–EIN24 |
| IF4 | 19 | EIN25–EIN32 |
| IF5 | 20 | EIN33–EIN40 |
| IF6 | 21 | EIN41–EIN48 |
| UF1 | 23 | AUS1–AUS8 |
| UF2 | 24 | AUS9–AUS16 |
| UF3 | 25 | AUS17–AUS24 |
| UF4 | 26 | AUS25–AUS32 |
| UF5 | 27 | AUS33–AUS40 |
| UF6 | 28 | AUS41–AUS48 |
Eight points per module, in order — exactly the arithmetic in HANDOVER.md, now corroborated by the drawing rather than assumed.
✅ CONFIRMED 2 Sep 2026 - the assumption is closed. The IF1 and IF2 sheets name their functions, and they match MW310.EQU for eight consecutive points: EIN8 EMERGENZA TERMICI = IF.8, EIN9 CONTROLLO VUOTO = IF.9, EIN10 AGGREGATI SU = IF.10, EIN11-EIN13 LAMA SU and OVER-RIDE = IF.11/IF.12+, EIN14-EIN16 OVER-RIDE and TELERUTTORE INSERITO = IF.15/IF.16. Independently corroborated on the Panasonic sheet (page 10), whose I/O cross-references land on sheet 28 = UF6 and sheet 20 = IF5.
EIN n = IF.n and AUS n = OF.n. The LED-photography exercise is no longer needed to establish the I/O mapping.
Finding 2 — the drives are wired for analog speed reference (strongly indicated)¶
The axis drive sheets show, against the 1CN connector of each SGDH drive, the signal group:
... AZIONAMENTO ASSE X ... CONNETTORE 1CN ... SGDH-15DE ... START / DRIVER OK / AVANTI / INDIETRO / RESET / REFERENCE / 0V
REFERENCE and 0V on 1CN is the speed reference input and its ground — i.e. V-REF and SG, CN1 pins 5 and 6. Sheet 11 (COLLEGAMENTI SERIALI) also carries a note reading CN YASKAWA SER SIGMA DRIVERS CN 1/F X-Y-Z CN 5|6, which appears to be exactly the pins 5/6 reference.
This is the third independent signal pointing at analog velocity mode, alongside Risoluzione DAC=12 bit in Mw310.ini and the DAC values seen on the homing screen. It is not proof — Pn000.1 read at the drives is still the deciding evidence — but the wiring is consistent with Option B and the 7I77.
Finding 3 — encoders land on 2CN, not CN1¶
Each drive's motor encoder connects at 2CN (2CN.X, 2CN.Y, 2CN.Z), via Yaskawa connector 3108A2029SPHM18, part 025MSC0014. Sheets 29–32.
✅ ANSWERED 2 Sep 2026: they are already wired. Pages 7-9 show an 8X0.22 sch screened cable on CN1 pins 1, 33, 35, 19, 34, 36, 20, 50, labelled + A B O A-bar B-bar O-bar -. All three differential encoder pairs run from each drive into the cabinet under Option B. Nothing needs adding at CN1. See servo-drive-interface.md.
What to do with this¶
- To answer a specific wiring question, open the full-resolution PDF at the sheet named above rather than searching 40 pages.
- The OCR is patchy on numbers — wire numbers and pin numbers read from it must not be trusted. Read those from the actual sheet.
- Sheets worth reading properly and early: 11 (serial connections and drive command wiring), 16 (IF1, to test the
EIN8= E-stop prediction), and 29–32 (encoders, to establish whether1CNencoder outputs are wired).
