Product Description:

The PY0A030A1N51P01 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. Serving as the intermediary between a motion controller and matching Super BL servomotors, it interprets command pulses, feeds regulated current to the motor windings, and engages an internal dynamic brake when required. The module supports tight position loops and stable velocity control on pick-and-place axes, index tables, and other high-precision automation stages.

Its continuous output capability is 30 A, supplying sufficient armature current for medium-capacity servomotors. For acceleration peaks, the circuit permits a surge of 40 A before the protection timers limit conduction. Power arrives through a single-phase 200 VAC mains connection that also energizes the brake resistor path. The current loop bandwidth supports applications up to 400 Hz, so torque remains linear even with low-inductance windings. Differential command lines can be clocked at rates up to 2.6 M pulse/s, letting high-resolution controllers issue tight step counts without pulse loss. Position-mode operation pairs with a 2000 P/R incremental encoder, and service headers provide 2.0 V current and velocity monitor points for oscilloscope tuning.

The brake stage acts within 6.5 ms and can dissipate up to 360 J of regenerated energy, allowing the axis to stop without external resistors on most loads. The velocity control range spans 1:5000, enabling slow alignment moves and full-speed production with the same hardware. The housing weighs 2.2 kg, so it adds little mass to panel-mounted installations. Current and velocity monitors maintain ±10% linearity relative to their 2.0 V span. The encoder channel preserves stable feedback and helps keep the position loop closed across the supported operating range.
