Yaskawa SGDH-15DE – 1.5 kW Sigma-II SERVOPACK for 200–230 V systems with DeviceNet control

The Yaskawa SGDH-15DE is a Sigma-II AC servo amplifier sized for 1.5 kW applications. From my experience, this model is a good fit when you want the robustness of Sigma-II with DeviceNet fieldbus control and straightforward cabinet mounting. You might notice that it excels in packaging lines, pick-and-place stations, and retrofits where an installed DeviceNet network is already in place. Response is quick, tuning tools are familiar, and it plays nicely with Yaskawa Sigma-II motors and encoders.

Key Features

• 1.5 kW capacity (200 V class) – Sized for mid-range axes on cartoners, winders, and index tables.
• DeviceNet fieldbus control – Typically used in brownfield systems; makes integration with DeviceNet PLCs straightforward.
• Sigma-II ecosystem compatibility – Works with Yaskawa Sigma-II motors and serial encoders; commissioning is predictable.
• Fast servo response – Stable speed/position control with auto-tuning that, in many cases, reduces settling time without hunting.
• Compact, book-style chassis – Saves cabinet space and mounts cleanly alongside other drives.
• Protection and diagnostics – Alarms and status I/O help maintenance teams pinpoint issues quickly.
• Reliable in industrial environments – Designed for 0–55°C ambient operation with proper ventilation.

Technical Specifications

Where it fits well

A packaging OEM told us they swapped this unit into a legacy DeviceNet cell to stabilize a 1.5 kW infeed axis; tuning went faster than expected and they didn’t have to touch the PLC logic. It also seems to be a safe pick for indexing conveyors or turret applications where accurate positioning and quick settle are more important than ultra-high-speed profiles.

Related or Supporting Products

• SGDH-15AE – Same 1.5 kW capacity with pulse/analog reference instead of DeviceNet; a better choice if your controller outputs pulse train.
• SGDH-10DE / SGDH-20DE – Same interface family in 1.0 kW and 2.0 kW capacities for adjacent axes.
• Sigma-II Motors (SGMAH / SGMAV / SGMGH series) – Match the motor series and encoder to the 1.5 kW class for best performance.
• Motor and Encoder Cables (JZSP- series) – Factory cables for power and feedback to ensure shielding and EMC compliance.
• Regenerative Resistors – Recommended where decel duty is high; size to match braking duty of the 1.5 kW axis.

Installation & Maintenance

• Cabinet environment – Mount vertically in a sealed panel with 50 mm (min) clearance above/below; keep ambient 0–55 °C and provide forced ventilation.
• Power and grounding – Use a dedicated 200–230 VAC supply for the 1.5 kW class; bond PE ground with low impedance and follow EMC grounding practices.
• Wiring – Shielded motor/encoder cables routed away from high-power lines; keep DeviceNet trunk and drops within ODVA guidelines.
• Tuning & startup – Start with auto-tuning; verify encoder direction and limit switches; set DeviceNet node ID and baud rate as required by the PLC.
• Routine maintenance – Quarterly dust cleaning, visual terminal checks, fan inspection (if equipped), and firmware updates where applicable.
• Safety – Lockout/tagout before service; verify STO/enable circuits; keep clearances around braking resistors due to heat.

Quality & Certifications

• CE and UL/cUL conforming (typical for Yaskawa Sigma-II drives)
• RoHS compliant in most later production batches
• Manufacturer reputation for long lifecycle support and robust spares availability
• Backed by our 365-day warranty

If you’re replacing an existing SGDH-15DE, share the exact motor model and any network settings; we can pre-check compatibility and help you avoid downtime. One thing I appreciate is how predictable the Sigma-II behavior is during a swap—usually it’s commission, tune, and go.
