Accurate thermal simulation platform software ensures thermal reliability. Each VFD500 inverter undergoes comprehensive thermal simulation testing before physical prototype development, with results closely matching actual test outcomes. Thermal simulation can replace actual load simulation in limit test conditions.

Complete machine temperature rise testing uses severe cyclic overload protocols to ensure long-term reliable operation under extreme conditions:

• 1.5 times overload current for 1 minute
• Ambient current for 4 minutes
• 1.5 times operation for 1 minute at 40°C ambient temperature
• Continuous 5-minute cycles until thermal equilibrium

Full series includes output to ground short circuit protection, over current protection, drive overload protection, motor overload protection, drive over temperature protection, and optional PT100/PT1000 motor over temperature protection. Multiple high-quality three-proof paint with automatic spraying ensures uniform coating thickness and batch consistency.
