5. Selection and Installation Points

• ​Compatibility:
  • Needs to be paired with SINAMICS G120 power modules (such as PM240 – 2, PM250, etc.), and the power level should be selected according to the load requirements.
  • Compatible Motors: 1LA/1LG series induction motors, 1PM/1FK/1FT series servo motors.
• ​Heat Dissipation Requirements:
  • The power module needs forced air cooling or radiator installation to ensure heat dissipation efficiency.
• ​EMC Protection:
  • Inverters need to be configured with input filters (such as Class A or Class B filters) to meet electromagnetic compatibility standards.
• ​Debugging Tools:
  • Use SINAMICS Assistant or TIA Portal for parameter setting and debugging.
