Product Description:

The PY9A050U0XXXC03 servo amplifier is produced by Sanyo Denki as part of the PY Super BL Servo Amplifiers series. It links a motion controller to a brushless motor, shaping command signals into controlled three-phase currents that sustain tight velocity and torque regulation in automated assembly lines, pick-and-place stages, and packing equipment. Integrated control logic, power switching, and monitoring functions are delivered in one enclosure for straightforward panel installation within industrial cabinets.

The control section runs from a single-phase supply of 200 to 230 VAC, while the power stage draws three-phase 200 to 230 VAC to energize the motor windings. Command inputs present an impedance of 10 kΩ, allowing direct connection to most ±10 V analog outputs without excessive loading. When power is first applied, the control circuit can draw an inrush current of up to 40 A, and the main circuit can momentarily reach 18 A; these inrush currents inform fuse and breaker sizing. Normal operation is synchronized to 50/60 Hz mains with a ±3 Hz tolerance, and torque limiting is achieved through a ±2.0 VDC reference that caps drive current according to the external command profile. A 2.0 V feedback port reflects instantaneous phase current so the controller can verify loop stability.

Speed regulation extends across a ratio of 1:5000, and loop gain is maintained up to 400 Hz, giving the amplifier the bandwidth needed for high-precision indexing tasks. The chassis tolerates relative humidity up to 90% RH and temperatures from 0 °C to 55 °C during operation, with a storage temperature range of −20 °C to 65 °C. Velocity feedback is provided as a 2.0 V analog signal that scales with motor speed, while the unit has a mass of 4.4 kg, easing installation on DIN rails or bulkhead plates without requiring additional structural support.
