Internal Product Review
The PY0A015A1GA1P01 is a Sanyo Denki PY Super BL servo amplifier designed for position control with single-phase input power. A 15 A amplifier capacity and 400 Hz frequency characteristics give the unit strong responsiveness and stable motion performance. Incremental encoder feedback at 2000 P/R and a 1:5000 velocity control range make this amplifier an excellent choice for precise speed regulation.

Product Description:
The PY0A015A1GA1P01 servo amplifier is produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. It drives Super BL servo motors on precision positioning axes, converting utility power into regulated motor current while using incremental encoder feedback for closed-loop correction. Through its position control interface, the amplifier exchanges command and feedback signals with a motion controller. It supports encoder resolutions of 2,000 pulses per revolution, giving the machinery accurate shaft-angle information during rapid moves.
The amplifier can deliver a continuous output of 15 A, which is the maximum steady motor phase current available for acceleration and load holding. It accepts a single-phase AC supply, so cabinet wiring stays simple in small machines. Internally, the current loop bandwidth is tuned for 400 Hz, allowing tight velocity regulation without instability. To protect the power stage, a current-limiting circuit activates when the command reaches 2.0 VDC ±10%. Beyond this threshold, the drive limits additional output until the overload clears. Velocity can be adjusted over a ratio of 1:5000, allowing the same speed loop to handle slow jogging and high-speed indexing without parameter changes. A separate velocity monitor port reproduces the actual speed as a 2.0 V signal so external instruments can track motion in real time.
During power-up, the control electronics experience a surge of 40 A, while the main power section draws 18 A; circuit breakers and inrush limiters must therefore accommodate these peaks. When an emergency stop occurs, the dynamic brake engages in 6.5 ms and can absorb up to 360 J of kinetic energy before the regenerative resistor reaches its thermal limit. The factory-fitted resistor is rated at 20 W and 100 Ω, providing heat dissipation during frequent decelerations. The amplifier has an overall mass of 2.2 kg, allowing it to be mounted on light DIN rails without extra support.
