Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Yaskawa SGDH-30DE-OY is a 3.0 kW digital AC servo drive belonging to the Sigma II Servopack series. Operating on a 3-phase AC input supply ranging from 380 V to 480 V AC, this drive utilizes sine wave pulse-width modulation (PWM) control to operate 400 V class AC servomotors. It delivers a continuous output current of 11.2 A with a peak output rating of 28.0 A, serving as a core motion component in multi-axis CNC machining centers, automated packaging systems, robotic assembly arms, and gantry transfer drives. The unit supports versatile operation across position, speed, and torque control modes to deliver smooth motor rotation and rapid dynamic response.
Connecting and commissioning a replacement SGDH-30DE-OY unit requires attention to interface matching and configuration transfer. The drive features a CN3 serial port supporting RS-232, RS-422, and RS-485 Modbus RTU communication, alongside an internal option card expansion slot (CN5) designed for fieldbus cards including MECHATROLINK (JUSP-NS100), DeviceNet (JUSP-NS300), and PROFIBUS-DP (JUSP-NS500). Parameter profiles are stored in non-volatile internal EEPROM, meaning a spare unit is rarely plug-and-run. Field service personnel must back up and load parameter settings using SigmaWin+ configuration software or handheld Digital Operators (JUSP-OP02A or JUSP-OP03A), or draw on expert assistance from ABC Industrial Parts for parameter extraction from donor boards.
For operational status monitoring and diagnostic troubleshooting, the SGDH-30DE-OY is equipped with a 5-digit LED front-panel display and a dedicated red CHARGE LED indicator. The CHARGE LED provides an essential safety indication whenever dangerous DC bus voltage is present across the main circuit capacitors. Diagnostic software utilities allow operators to review historical error logs via function code Fn000 or execute independent motor rotation checks using Fn002 and Fn003 JOG test modes. Initial field troubleshooting should verify 3-phase line input voltage, CN2 encoder cable latching and shielding, and motor output phase continuity across U, V, and W terminals. When internal microprocessor exceptions or power hardware faults occur, on-site board repair is not viable, and acquiring a tested exchange unit or professional repair through ABC Industrial Parts provides the fastest path back to production.

Programming and Configuration
Programming and parameter management on the Yaskawa SGDH-30DE-OY Servopack center around its integrated non-volatile EEPROM memory. This non-volatile storage retains drive configuration profiles without requiring battery power. Parameter settings define control operating modes—including position, speed, and torque modes—as well as current limits, feedback ratios, and custom system gains. Parameter modification and system setup can be performed through PC-based SigmaWin+ diagnostic software via the CN3 port or manually using handheld JUSP-OP02A and JUSP-OP03A Digital Operators.
To simplify drive commissioning and dynamic tuning, the unit includes adaptive autotuning features. Real-time online autotuning continuously monitors load inertia fluctuations during operation, automatically updating loop gain parameters to maintain stability and response speed. Function code Fn005 provides a full parameter initialization to factory defaults when reconfiguring a drive, after which application-specific parameters must be written back to the drive.
Communication and System Integration
The SGDH-30DE-OY provides serial and fieldbus interface options to integrate into broader automation networks. The onboard CN3 serial communications port supports Modbus RTU protocol across RS-232, RS-422, or RS-485 physical links, establishing connections to host controllers, HMIs, and diagnostic equipment. Encoder feedback is interfaced via the dedicated CN2 port, supporting direct communication with high-speed serial incremental encoders as well as 17-bit absolute encoders.
For real-time industrial fieldbus connectivity, the Servopack includes an internal CN5 option card slot. Installing specific expansion modules into slot CN5 allows direct integration into MECHATROLINK-I/II (JUSP-NS100), DeviceNet (JUSP-NS300), or PROFIBUS-DP (JUSP-NS500) communication networks. Proper physical alignment and mechanical seating of option cards in CN5 are critical to prevent fieldbus communication faults during operation.
Diagnostics and Status Indication
System state monitoring on the SGDH-30DE-OY relies on a 5-digit LED display located on the front panel, combined with physical status LED indicators. The 5-digit display shows active alarm codes, parameter addresses, and operating state data. Operators can utilize diagnostic function routines to access historical fault records using code Fn000 or execute isolated motor rotation checks using Fn002 and Fn003 JOG operation functions to test motor movement independently of external command signals.
The drive also features a red CHARGE LED located on the front housing. This safety indicator lights up whenever main circuit DC bus voltage is present across the internal power capacitors, serving as a warning against touching electrical terminals.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CHARGE | Red - Solid | Illuminated when main circuit DC bus voltage is present. Indicates hazardous voltage on main circuit capacitor. |
Replacement and Spare Part Considerations
When replacing an SGDH-30DE-OY drive, confirm that the replacement matches the original 3.0 kW power rating and 380–480 V AC 3-phase input specifications. Mismatches between drive output capacity and motor power ratings lead to alarm code A.05 (Combination Error). In addition, any fieldbus communication option modules installed in slot CN5—such as MECHATROLINK, DeviceNet, or PROFIBUS-DP cards—must be mechanically transferred to the replacement Servopack to preserve network integration.
Parameter transfer must be completed before putting a spare unit into production service. Drive parameters stored in non-volatile EEPROM should be downloaded from the original unit using SigmaWin+ or a Digital Operator (JUSP-OP02A or JUSP-OP03A) and uploaded to the replacement drive. If an absolute encoder system is utilized and backup battery power was lost, maintenance technicians must execute the absolute encoder setup utility (Fn008) to clear encoder alarms and re-establish machine zero reference positions.
