Functional Features:
-
Model Suffix PBNAS2: P = Standard performance, B = No brake chopper, N = No safety card (or base), A = Analog I/O, S2 = Specific firmware/option configuration.
-
Dual-channel STO (SIL CL3/PLe) available with optional safety card.
-
Supports feedback: Resolver, SinCos (EnDat 2.1/2.2, BiSS-C, HIPERFACE), Incremental (ROD), SSI.
-
Expansion slots for Profibus, SERCOS, DeviceNet, SynqNet, PosI/O.
-
MMC/SD card slot for parameter/firmware storage.
-
-
Application Scenarios: High-precision CNC, printing presses, robotic arms, food & beverage processing machines, aerospace test rigs.
-
Structural Characteristics: Book-type modular housing, slot-based option card architecture, forced air cooling, top/bottom power terminals, front I/O connectors.
-
Working Principle: Digitally processes position/velocity commands from fieldbus or analog inputs, closes current loop at high speed, generates SVM-modulated output to motor phases with real-time compensation.
-
Installation Requirements: Maintain minimum spacing for airflow; mount vertically in grounded enclosure; separate power and signal cabling; torque terminals to spec.
-
Usage Notes: Only qualified personnel should handle; no maintenance required under normal use but fans (if option F2) need periodic cleaning; not for explosive environments.
