Product Description:
The PSI6300.333-L2 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. It serves as the welding current source and sequencing unit in automated resistance-welding lines, coordinating electrode pressure and current timing so each joint receives the required heat profile. By combining power conversion with digital control, the unit replaces bulky line-frequency transformers and allows compact installation near the welding station. Its medium-frequency operating principle also helps the system respond quickly to changing weld conditions during repetitive production cycles.
This inverter accepts three-phase input power of 480–690 VAC and uses forced-air cooling to maintain semiconductor temperature during high-duty cycles. The housing carries an IP20 degree of protection, making cabinet mounting necessary while permitting use in controlled indoor environments without specialized seals. Internal logic runs from a separate 24 VDC control supply that remains active during line disturbances, preserving process data in buffered RAM program memory. Current regulation is performed in discrete steps of 10 A, allowing fine adjustment of weld energy across dissimilar sheet gauges. Machine-level communication uses INTERBUS, and the same fieldbus also supports the integrated timer so sequence changes move across a single network. Programming is completed locally through a V24/RS232 link that terminates on a nine-pin D-Sub connector.
The stored library holds up to 256 programs, and the controller can address 5 electrode pairs and schedule up to 9 current impulses per cycle. This allows one controller to manage varied welding routines on transfer lines where joint geometry and material thickness change from station to station. Three independent weld-time parameters per program provide squeeze, heat, and hold intervals to match material stacks. Data retention during power loss is handled by an AA 3.6 V lithium backup cell with a service life of 2 years, so shift counters and quality statistics remain intact when the plant is offline.
