Kollmorgen S724OS-NANAPM
-
Product Name: S700 Series Digital Servo Amplifier (S724 variant)
-
Product Introduction: Part of the Kollmorgen S700 family, these are high-performance fully digital servo drives designed for complex single and multi-axis motion control. The suffix “NANAPM” typically denotes specific options including mains voltage, safety features (STO), and communication interfaces (e.g., analog/pulse).
