Product Description:

The PY0A030T1N51P01 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. As a drive component, it supplies regulated current to a matched brushless servo motor and relays positional feedback to the controller, forming the power and control link in compact automation axes. It is intended for positioning tables, pick-and-place heads, and other motion tasks where tight velocity loops and quick braking cycles are required.

During operation, the power stage provides an amplifier capacity of 30 A, which is the maximum continuous output current available to the motor windings. A brake delay time of 6.5 ms allows the circuitry to engage dynamic braking almost immediately after a stop command, while a brake energy limit of 360 J indicates how much kinetic energy can be dissipated without triggering a fault. The control electronics draw 40 VA from the auxiliary supply and have a control inrush current of 40 A at power-up, which can affect fuse sizing on the low-power side. The unit uses a full-closed-loop control configuration that accepts position feedback through a 2 MHz full-close encoder input and an RS-422 external encoder port. Single-phase input simplifies mains wiring, and the position control interface supports indexing drives that receive command pulses from a motion CPU. A sensor resolution of 2,000 pulses per revolution is supported, providing reliable interpolation for smooth velocity profiles.

The power section is designed for a supply of 200 VAC, and the main circuit absorbs up to 1.0 kVA during rated motion. The main circuit has an inrush current of 18 A during the first half-cycle, so inrush limiters or slow-blow circuit breakers are recommended. Regenerative energy is handled internally by a resistor network. Its effective power rating is 20 W, and the resistor presents 50 Ω to the DC bus, permitting repetitive deceleration without external units.
