Product Description:
U508BN-012S18 is a latest module from Sanyo Denki’s state-of-the-art Super DC Servo Motors product range. The component uses analog command inputs within ±10V, ensuring it aligns seamlessly with industrial-grade control power standards. The component accepts a resolver max drive current of 55 mA AC‑RMS which allow strong signal excitation. It outputs 2 VAC resolver voltage to provide robust sensing signals. This variant also delivers 80 W of continuous output power, making it suitable for moderate-load industrial solutions.
It operates at a rated speed of 3000 rpm, enabling fast rotational response ideal for high-throughput motion control applications. Drawing 1.7 ampere during industrial operation, this establishes exact drive ampacity needs while managing power flow and optimizing control architecture. The resolver’s 7-8 kHz modulation frequency effectively suppresses electrical interference in signal transmission. Its peak quadrature resolution of 65,536 counts per revolution enables ultra-precise motion tracking. It supports feedback from encoder formats like Resolver and Hall, broadening sensor integration options. An input voltage of 4.25 VAC for the resolver guarantees consistent excitation for reliable and stable loop feedback. This allows a maximum feedback cable length of 75 ft (22.9 m) to preserve signal quality in distributed systems.
The resolver max DC resistance of 120 Ω ensures the winding remains safe under standard load conditions. Control modes of U508BN-012S18 include velocity control to support smooth speed regulation and torque (current) control which enables direct torque adjustment. The 3 MHz of encoder output frequency limit simply allows top-speed encoder compatibility. Integration features a 7‑segment LED status display that allows straightforward operational monitoring. The drive shows a typical repeatability of ±0.02° which enables consistent motion accuracy. It also indicates a thermal time constant of 85 s which allows predictable motor heating behavior during sustained use.
