Technical Specifications

Selection Notes

The DP/PN designation reflects the built-in PROFIBUS DP and PROFINET interfaces, letting the controller act as fieldbus master on both networks without an add-on module. Its ULTRA-HIGH class raises the axis ceiling to 128 and adds a 0.125 ms minimum servo cycle option (with ET 200SP, SCOUT TIA V4.5 or higher, and SERVO-FAST), well above the axis count available on this family's STANDARD-performance variant. The 388 Mbyte RAM work memory and 46 W typical power loss are both roughly triple the STANDARD unit's figures, reflecting the extra processing headroom needed for large multi-axis programs. This part is listed as a spare part, so confirm current SIMOTION Kernel and runtime compatibility before replacing an in-service D455-2.
