Product Description:
The PY0A015A1G91P01 is a servo amplifier manufactured by Sanyo Denki within the PY Super BL Servo Amplifiers series. The module operates from a single-phase mains supply and provides a position control interface, making it suitable for pick-and-place actuators, indexing tables, and other motion axes that require tightly coordinated positional accuracy. By translating drive commands into accurately modulated current, the amplifier supports industrial automation cells where rapid response and repeatable motion profiles are required.
Output capability centers on an amplifier capacity of 15 A, which represents the continuous current that the power stage can deliver to a matched brushless motor. Loop bandwidth is supported by frequency characteristics reaching 400 Hz, so velocity and position corrections can track high-speed command sequences without noticeable lag. During power-up, the control electronics can draw a surge of 40 A, an inrush value that assists with proper fuse and circuit breaker sizing. Feedback resolution is fixed at 2000 P/R, reflecting the number of incremental encoder pulses counted per shaft revolution and establishing the minimum positional increment that the drive can resolve. Speed regulation spans a 1:5000 velocity range, enabling precise low-speed movement as well as rapid traversal from the same amplifier.
Thermal energy generated during dynamic braking is initially dissipated through a 20 W internal regeneration circuit paired with a 100 Ω resistor. Loads with greater inertia can be accommodated by connecting external regeneration hardware rated up to 600 W. The main power channel experiences an 18 A inrush current at startup, while the separate 40 VA control power supply sustains logic functions. An integrated 200 VAC power unit includes a dynamic brake that limits overshoot when the axis decelerates. Incremental encoder feedback is monitored through a 2.0 V ±10% velocity signal, providing the amplifier with motion data for closed-loop control. The assembly has a mass of 2.2 kg, allowing secure installation without placing excessive load on the cabinet structure.
