Wake Industrial LLC is not an authorized distributor of this product.
The Sanyo Denki PY0A050A1G3MP01 is a servo amplifier from the PY Super BL Servo Amplifiers series. It operates with a main circuit input of three-phase 200-230 VAC at 50/60 Hz and features a control circuit input of single-phase 200-230 VAC. This servo amplifier has a mass of 4.4 kilograms and supports a velocity control range of 1 to 5000.
Internal Product Review
The PY0A050A1G3MP01 is a Sanyo Denki servo amplifier that stands out for straightforward integration with a 3-phase 200-230 VAC main circuit input and a 1-phase 200-230 VAC control circuit input. Technical performance is especially impressive, with 400 Hz frequency characteristics and a 1:5000 velocity control range supporting responsive, accurate drive behavior. Low load variation of ±0.1% max/max speed makes the amplifier an excellent choice for consistent high-precision operation.

Product Description:
The PY0A050A1G3MP01 is a servo amplifier manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. The unit interfaces between factory mains supplies and Super BL servo motors, shaping current and voltage so a motion controller can command precise acceleration, speed, and dynamic braking. By supervising feedback and regulating power, it supports positioning tables, pick-and-place heads, and conveyor drives that require stable closed-loop performance across a wide operating temperature and line-voltage range.
The control section accepts a single-phase input of 200–230 VAC at 50/60 Hz, and an initial inrush of 40 A for 1 ms indicates the instantaneous current drawn by its capacitive filter when energized. Motor power is delivered through a bus rated at three-phase 200–230 VAC. Soft-start circuitry holds the main-circuit inrush to 18 A for 600 ms, reducing the risk of tripping upstream circuit breakers. During commanded deceleration, the internal dynamic brake engages after 24.0 ms and can absorb up to 1800 J of regenerative energy, preventing DC-link overvoltage. With the load inertia matched to the motor inertia (JL = JM), the velocity loop maintains a bandwidth of 400 Hz, and speed error from load or supply changes stays within ±0.1%.
Continuous service is permitted from 0 to 55 °C, while storage down to −20 °C allows the unit to remain in unheated storage areas. The chassis weighs 4.4 kg, allowing panel mounting without additional supports. Internal regulation limits drift caused by ambient temperature to ±0.5% of maximum speed, and line-side voltage fluctuations contribute no more than ±0.1% deviation. A velocity control range of 1:5000 lets the amplifier deliver slow creep movements as well as full-rated travel. The 40 VA control supply isolates the logic circuitry from the power stages to maintain stable operation during transient events.
