– Power and motor connection terminals are pluggable, and the radiator fan can be easily replaced.
- Common Issues and Maintenance
- Fehlerbehandlung
Overvoltage Alarm (z.B., 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 (z.B., PROFINET, DP, or RS485) to avoid compatibility issues caused by mixing.
- Wartungsempfehlungen
– 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.
