III. Supply and Procurement
Spot Supply: Inventory is still available in the market in 2025. For example, Hebei China Electric can deliver within 3 days, with a total supply of 1,000 units.
- Installation and Commissioning
- Installation Key Points
– Shielding plates and EMC connection strips need to be installed to ensure electromagnetic compatibility. The built-in filter model should be selected according to actual requirements.
– Power and motor connection terminals are pluggable, and the radiator fan can be easily replaced.
- Common Issues and Maintenance
- Fault Handling
Overvoltage Alarm (e.g., F0002): Check if the power supply voltage is within the allowable range (P0210), adjust the ramp-down time (P1121), or add a braking unit.
Communication Interface Issues: Select the correct model according to requirements (e.g., PROFINET, DP, or RS485) to avoid compatibility issues caused by mixing.
- Maintenance Recommendations
– Regularly inspect the power supply board and power modules to prevent strong electrical interference with weak electrical circuits.
– Ensure good heat dissipation, with the ambient temperature not exceeding 55°C (PROFINET models support side-by-side installation).
- Alternative Models and Upgrades
Communication Requirement Changes: For a DP interface, select 6SL3210-1KE23-2UP1; for RS485, select 6SL3210-1KE23-2UB1.
Function Expansion: For higher performance, consider the SINAMICS G120 modular frequency converter, which supports flexible configuration of control units and power modules.
