Key Notes
- Single-Quadrant Operation: Only motoring (forward direction); braking requires external resistors or a 4Q unit.
- US‑Rating: 1504 A is the UL/CSA compliant current for North American installations (lower than the 2000 A IEC rating).
- Successor: 6RA8095-4KS22-0AA0 is a 2-quadrant drive with similar ratings, improved efficiency, and modern communication (PROFINET optional).
