Expert FAQs for System Integration

What size Sigma II servomotor should I pair with the SGDH-50DE?

Match the amplifier's 16.5A continuous output current to a motor with a similar or lower rated current. Common matches include the SGMGH-44A or SGMSH-55A models. Always consult the Yaskawa Sigma II sizing catalog for the optimal torque-speed combination for your load.

Can I use this drive on a 400VAC European or 480VAC North American line?

Yes, the Yaskawa SGDH-50DE input range of 380-480VAC covers both common industrial voltages. You do not need to change taps or hardware. The drive automatically adapts to the supplied voltage within this range.

How do I handle regenerative energy from the motor with this amplifier?

The SGDH-50DE requires an external regenerative resistor for applications with high inertia or frequent deceleration. You must select and install an appropriately sized resistor on the drive's designated terminals to prevent overvoltage faults.

What is the most common setup mistake with this servo drive?

Incorrectly setting the motor model and feedback type parameters. If these auto-tuning parameters are wrong, the system may exhibit vibration, overheating, or erratic motion. Always correctly input the exact servomotor model code from its nameplate during initial setup.

Is there a recommended maintenance schedule for long-term reliability?

Perform periodic visual inspections for dust accumulation and check terminal tightness annually. The key maintenance item is the DC bus capacitors. For continuous operation, plan for a professional inspection or replacement of electrolytic capacitors after approximately 7-10 years of service.
