PY9A300U0XXXC07
by Sanyo Denki
The Sanyo Denki PY9A300U0XXXC07 amplifier is part of the PY Super BL Servo Amplifiers series, designed for demanding industrial automation applications. It delivers a rated output of 4500 W at a rated revolution speed of 2000 rpm and provides a rated torque of 21.5 N·m. With an induced voltage constant (k eϕ) of 36.7 mV/min⁻¹ and a torque constant (k t) of 1.05 N·m/Arms, the unit ensures precise motor control and smooth acceleration.
This servo amplifier features a rapid electrical time constant of 33 msec and a mechanical time constant of 0.68 msec, excluding sensor delay, supporting high dynamic response and stability. It sustains an instantaneous maximum stall torque of 70.0 N·m and an instantaneous maximum stall armature current of 79.7 Arms, enabling short bursts of high-load operation. The phase armature resistance is only 0.043 Ω, minimizing power loss and heat generation. A continuous stall torque rating of 32.0 N·m and corresponding continuous stall armature current of 31.6 Arms highlight its capacity for sustained heavy-duty cycles.
Engineered for robustness, the PY9A300U0XXXC07 operates reliably in up to 90% relative humidity without condensation and at altitudes to 1,000 meters above sea level. It endures vibration up to 0.5 G across X, Y and Z axes (10–55 Hz, two hours) and shock up to 2 G, ensuring high durability in harsh factory environments. The amplifier’s precise monitoring outputs, including a 2.0 V velocity monitor and 2.0 V current monitor, enhance diagnostic efficiency and preventive maintenance. Together, these features deliver stable, high-performance operation and long service life in critical industrial control systems.
