Product Description:

The PY0A015A1M51P01 servo amplifier is manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. It interfaces between a motion controller and a matched brushless motor, modulating stator current so position, velocity, and torque follow commanded profiles. In automated pick-and-place modules, feed drives, or labeling systems, the unit supplies regulated power, initiates dynamic braking, and routes regenerated energy to an external resistor. This design provides a compact means of managing motor behavior during rapid directional changes.

Its output stage is rated for 15 A, providing the current margin needed for peak torque transients. The control and main circuits accept a 200 to 230 VAC single-phase input, while the logic section draws 40 VA under a steady load. At power-up, the control board can momentarily demand 40 A, and the main bus experiences an 18 A inrush current, so protective devices must accommodate these surges. A dynamic brake engages after 6.5 ms and can dissipate 360 J through its internal network. Additional energy is diverted to a 20 W, 100 Ω regeneration resistor so the DC bus remains within safe limits during abrupt deceleration.

Servo accuracy is supported by a bandwidth of 400 Hz, allowing the current and velocity loops to react quickly to command changes. The amplifier operates with a mains frequency of 50/60 Hz ±3 Hz, simplifying installation in regions that use either standard frequency. Closed-loop speed regulation spans a 1:5000 range, so slow indexing and high-speed traverses can be driven by the same hardware. Continuous operation is permitted from 0 to 55 °C. The enclosure weighs 2.2 kg, which eases mounting on DIN rails or panel plates. The single-phase wiring arrangement matches the control input and supports straightforward integration into small machines.
