Product Description:

The PY0A050A0R31S01 Servo amplifier from Sanyo Denki is the optimal choice for industrial automation systems that require precise and high-performance motor control. Its modest size and steady performance make it an excellent choice for many motion control applications. Dependable performance under extreme situations is delivered by this servo amplifier, which finds usage in manufacturing equipment, robotics, and machine tools.

The PY0A050A0R31S01 servo amplifier is certified to meet international safety standards, including UL, TÜV, and CE, and it is compatible with both 3-phase input and output configurations. A three-phase 0-230V AC signal with a frequency range of 0-167 Hz is output, allowing for flexible control of motor speed and torque. Pulse Width Modulation (PWM) transition frequency of 20 kHz is one of the PY0 amplifier's distinctive features. This high switching frequency enhances the responsiveness and accuracy of motor control, as well as the audible motor noise. Drive efficiency and stability are guaranteed by the rated output current of 1.2 Amps, which remains constant even when the load changes dynamically.

Applications requiring consistent reliability and fine motor control are ideal for the PY0A050A0R31S01 amplifier due to its high level of precision, quiet operation, and wide compatibility. This means that it may be used safely and consistently all over the world. The rated input current of the amplifier is 1.3 Amps, and it can handle a three-phase AC input voltage of 200- 230V at 50/60 Hz. Its small size makes it easy to incorporate into confined control cabinets or preexisting systems, and the certification markings guarantee its safety, quality, and compliance.
