🎥 Yaskawa SGDV Sigma V Analog Voltage / Pulse Train – Static Check Guide
In this video, we walk through a step-by-step guide on how to perform a static check on the Yaskawa SGDV Sigma V AC Servo Drive, specifically for Analog Voltage and Pulse Train control applications. This diagnostic process helps detect potential faults in the drive’s power circuits, input/output stages, and control sections before installation or troubleshooting.

🔍 Step-by-Step Static Check Procedure
✅ 1. Safety First
🔸 Power off the drive and disconnect from all power sources.
🔸 Allow time for the DC bus to fully discharge before proceeding.

✅ 2. Measuring DC Bus Voltage
🔸 Using a multimeter, check the DC bus terminals to ensure voltage is fully dissipated.

✅ 3. Testing Input and Output Phases
🔸 Set the multimeter to diode check mode.
🔸 Probe the input terminals (R, S, T) and the output terminals (U, V, W) to verify balanced readings across all phases.

✅ 4. Ground Fault Detection
🔸 Switch the multimeter to resistance mode.
🔸 Measure the resistance between each phase and ground.
🔸 Any low resistance reading could indicate a short circuit or insulation failure.

✅ 5. Encoder Feedback Circuit Test
🔸 Check the encoder feedback signal to ensure proper signal integrity and communication.

⚙️ Common Faults Detected During Static Checks
🚨 Overcurrent Faults (OC Alarm) – Could indicate shorted output transistors or a phase-to-phase short.
🚨 Ground Faults (GF Alarm) – Points to damaged insulation or motor connection issues.
🚨 Voltage Imbalance – Indicates damaged power module components affecting input/output phases.
