Product Description:

The PYRA030E0XXXP00 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. It sits between a motion controller and a brushless servomotor, converting low-level reference signals into controlled phase current for industrial axes. In automated equipment, this unit manages torque, velocity, and position so machines follow programmed motion profiles accurately. Built-in dynamic braking and regenerative processing allow the amplifier to absorb and dissipate kinetic energy during rapid deceleration without requiring external hardware.

Continuous output capability reaches 30 A, allowing the drive to start and stop medium-frame servomotors without entering the current limit. Both torque and velocity loops accept a differential command of ±2.0 VDC, enabling direct connection to common PLC analog modules. Closed-loop bandwidth is maintained up to 400 Hz, which supports tight regulation when loads change quickly. The velocity control range is 1:5000, so the same amplifier can position an axis slowly or move it rapidly. A current-limit input with a ±10% tolerance and a monitor output provide external diagnostic systems with clear information about drive loading.

The chassis weighs 2.2 kg, minimizing enclosure mass while still accommodating the inductive components needed for internal regeneration. It tolerates continuous vibration up to 0.5 G and withstands shocks as high as 2 G during transport or abrupt machine movement. The rated service altitude is 1000 m, allowing operation in facilities located well above sea level. The amplifier remains functional at relative humidity levels up to 90% RH, making it suitable for humid factory environments when installed in an appropriate enclosure. An automatic brake circuit clamps the DC bus whenever regenerative voltage rises, helping control energy returned during motor deceleration.
