Product Description:

The PY0A050E0XXYPH1 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. In an automation cell, it supplies regulated current and dynamic braking to a matched servo motor so motion controllers can command speed or torque with closed-loop precision. The unit connects between the plant’s three-phase mains and the motor leads, translating line power into a pulse-width-modulated output suited to fast acceleration profiles.

The control section is energized by a single-phase 200 VAC supply and draws up to 40 VA, a rating that establishes the required capacity of the auxiliary supply transformer in the panel. On power-up, this circuit can momentarily draw 40 A; fuses and contactors must therefore tolerate that inrush without nuisance trips. Motor power is delivered from a separate three-phase 200 VAC input, isolating high-current motor switching from the logic supply. During overspeed conditions or commanded stops, the internal resistor network absorbs regenerated energy. Its energy limit is 1800 J, allowing the drive to dissipate that amount per event without exceeding its thermal margins. The associated brake delay is 24.0 ms, which is the time the amplifier waits before clamping the DC bus and allows motor flux to collapse within a predictable interval.

The housing measures 50 mm wide, 235 mm high, and 205 mm deep, so it fits in narrow rows of compact control cabinets. The chassis is secured to a back panel through four M5 mounting points, while the recommended terminal screw torque of 1.18 N·m helps prevent conductors from loosening. A dry, normally open relay labeled “READY” provides status feedback and is rated for 250 VAC at 2 A or 30 VDC at 2 A. The relay can drive PLC inputs when the minimum load of 5 VDC at 20 mA is supplied. The dynamic brake can be operated up to 10 cycles per hour, and the main input can withstand an 18 A inrush without exceeding its rated limits.
