Yaskawa Sigma and CACR servo drive replacement guide
Yaskawa servo-drive searches are usually exact-part replacement searches. SGDV, SGD7S, SGDH, SGDM, SGDR, SGDB, and CACR hardware can look similar in short search snippets, but the complete part number, suffix, drive family, and installed system configuration control the buying decision.
Current Outdwella exact-part pages
| Outdwella page | Primary buying check |
|---|---|
| SGD7S-3R5DC0B | Confirm Sigma-7 SERVOPACK family, capacity, voltage, command interface, safety option, and motor pairing. |
| SGD7S-370D30B | Match the full SGD7S suffix and verify tuning, feedback, controller interface, and trial operation requirements. |
| SGDR-SDA710A01B | Confirm legacy SGDR system fit, wiring, command interface, feedback type, parameter backup, and cabinet layout. |
| SGDM-30DN | Confirm SGDM legacy Sigma drive requirements, motor model, option boards, parameter files, and switch settings. |
| CACR-SRCA20BBB | Do not shorten the CACR suffix; verify whether the item is drive hardware, accessory hardware, interface hardware, or board-level replacement. |
Pre-order compatibility checklist
- Read the full part number from the nameplate, cabinet drawing, maintenance log, or spare-parts list.
- Confirm the family: SGDV, SGD7S, SGDH, SGDM, SGDR, SGDB, SGDS, or CACR.
- Verify motor model, encoder or feedback type, voltage, current or capacity, safety option, fieldbus or command interface, and connector layout.
- For accessory and option hardware, confirm module role, board revision where visible, compatible drive family, and cabinet wiring.
- Back up parameters, tuning data, alarm history, switch settings, and controller project files before replacement.
- Choose New or Used in Great Condition based on project standard, downtime risk, and budget.

FAQ
Can SGDV and SGD7S drives be substituted?
Do not assume direct substitution. Treat SGDV and SGD7S as different family references unless the machine documentation or a qualified controls engineer approves the replacement.
Are SGDR and SGDM drives current Sigma-7 equivalents?
No. SGDR and SGDM are legacy Yaskawa drive families and should be matched by the installed machine documentation, motor, feedback, wiring, parameters, and commissioning path.
Are CACR parts the same as SERVOPACK drive amplifiers?
Not necessarily. CACR items may be accessory, controller, interface, or drive-related hardware. Match the complete part number and installed system role before buying.
What should be checked before installation?
Confirm wiring, grounding, feedback, motor pairing, safety circuits, parameters, firmware expectations, alarm history, and commissioning steps before restarting the machine.
