Quality Control Process
Every replacement module undergoes strict electrical validation. We first verify the internal DC bus and power supply rails using a calibrated Fluke multimeter to ensure stable operation. Next, we perform dynamic load testing to confirm the drive handles current without overheating. We then inspect the feedback signal processing circuits to ensure accurate position tracking. All units ship in anti-static shielding.

Replacement Pitfall Guide
❗ Verify Encoder Feedback Configuration. This amplifier relies on precise closed-loop feedback. Ensure the connected encoder type (optical or magnetic) matches the drive’s configuration parameters. Mismatched feedback causes position errors and oscillation.
❗ Check Motor Wiring Terminals. Ensure the motor phase connections (U/V/W) and encoder cables are securely seated. Loose connections cause intermittent overcurrent or encoder alarms during high-speed operation.
❗ Beware of Overcurrent Alarms. If the drive throws an overcurrent fault, isolate the fault immediately. Disconnect the motor and test. If the alarm persists with motors disconnected, the internal IPM module may be damaged.
❗ Mind the Grounding and Insulation. Use a Megger to verify motor and cable insulation resistance. Poor grounding or degraded cable insulation is a leading cause of drive failure and electrical noise interference.
Keep these in mind and you’ll cut 90% of rework time.
