Product Description:
The PSI6100.354-L2 medium-frequency inverter is produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. It converts incoming three-phase power into a regulated medium-frequency output that drives coordinated welding or assembly electrodes in automated production cells. Its steel housing measures 463 mm high and 280 mm deep, permitting installation in standard control enclosures while shielding the integrated PS5 IBS OPC2 I/O board and INTERBUS-S communication hardware. The integrated control hardware allows the inverter to handle local I/O and network communication inside the same enclosure, reducing the need for separate auxiliary modules in the cabinet.
The unit accepts a supply of 480 – 690 VAC, allowing direct connection to high-voltage plant mains without external transformers. Thermal management is handled by an internal fan, and this air-cooled design removes the need for liquid circuits and simplifies cabinet layout. Field devices are referenced to 24 VDC discrete logic, matching typical PLC wiring conventions and minimizing interface hardware. A built-in sequencer runs at 1000 Hz, enabling millisecond timing for current, force, and motion phases. The enclosure is only 239 mm wide, so several inverters can be mounted side by side in a 600 mm deep panel, and the stop circuit can interrupt up to 3 A at 24 VDC to protect downstream equipment during faults.
The control architecture supports a minimum squeeze period of 16 ms, trimming nonproductive delays in high-throughput stations. Data exchange over INTERBUS-S reaches 2 MBaud, ensuring that process commands and feedback remain synchronized with the fast internal sequencer. Force commands are resolved with an 8-bit setpoint field, while individual weld or assembly positions are addressed through a 16-bit spot selector, giving adequate resolution for multi-electrode tooling. This arrangement supports rapid force profiles, precise spot targeting, and responsive fault handling during automated joining cycles. It also helps the inverter coordinate timing-sensitive operations when several actuator positions and process steps must run in a fixed sequence.
