⚙️ Electrical & Motion Control
The IC800SSI107RS1-DE accepts a 90–250 VAC supply and provides three-phase motor output for compatible servo applications. The published specifications identify a maximum continuous apparent input power of approximately 3.8 kVA, with output frequency capability up to 1000 Hz.
The S2K family was developed for high-performance standalone brushless servo or stepper applications and includes integrated motion controllers and user-configurable I/O functions.
🛠️ Application
This controller can be used in industrial motion-control equipment, machine tools, production machinery and other automation systems requiring controlled servo positioning and speed regulation.
For replacement applications, verify the complete part number, feedback type, motor rating, supply voltage and controller configuration before installation.
⚠️ Installation Notes
Disconnect all hazardous voltages before servicing. Confirm the motor and controller are correctly matched, particularly the resolver feedback configuration and current rating. The S2K documentation specifically warns that an improperly matched motor and amplifier can result in overload or component damage.
