Product Description:

The PY9A150U0XXXC04 from Sanyo Denki’s PY Super BL Servo Amplifiers product line marks its place as a high‑power drive solution. It offers a rated output of 4500 W which delivers ample power for heavy‑duty automation tasks. It operates at a rated revolution speed of 2000 min⁻¹ and sustains consistent motion for continuous‑run processes. The variation increases the operating range for quicker indexing and shorter cycle durations by supporting a maximum rotating speed of 2500 min⁻¹. The amplifier maintains steady force deliverance under typical loads by producing a 21.5 Nm rated torque.

It can also reliably handle abrupt load spikes by maintaining a continuous stall torque of 32.0 N·m (326 kg·cm) and an instantaneous maximum stall torque of 70.0 N·m (714 kg·cm). The device draws a rated armature current of 24.1 Arms so that it optimizes efficiency at full power. It tolerates a continuous stall armature current of 31.6 Arms, preventing frequent current‑limit trips. It withstands an instantaneous maximum stall armature current of 79.7 Arms. Additionally, it has a torque constant of 1.05 N·m/Arms, which means that it can precisely manage the torque production per ampere. With an induced voltage constant of 36.7 mV/min⁻¹ (36.7 V/krpm), this new model consistently provides back-EMF sensing for precise speed feedback.

It reacts a mechanical time constant of 0.68 msec for rapid response to control commands. With a phase armature resistance, showing 0.043 Ω and operates more efficiently by reducing I2R losses. The unit weighs 22.0 kg and offers a holding torque (brake option) of 32 N·m (326 kg·cm), securing loads firmly when idle. It accepts a main circuit power supply of single‑phase 200–240 VAC, 50/60 Hz and that matches standard industrial mains circuits. It provides an IP20 protection class, shielding internal components against solid debris larger than 12.5 mm.
