Product Description:

The PY0A015H0N86S00 servo amplifier is produced by Sanyo Denki and belongs to the PY Super BL Servo Amplifiers series. Designed to interface with brushless servomotors and upper-level motion controllers, it converts DC-bus power into precisely timed phase currents while monitoring feedback channels. This function lets automated assembly stations, pick-and-place modules, and packaging lines achieve repeatable motion profiles without adding mechanical complexity.

Its control section tolerates an inrush current of 40 A when the logic supply is energized, while the main power bus draws up to 18 A during capacitor charging. These electrical limits help prevent nuisance tripping of upstream breakers and minimize stress on contactors. Closed-loop speed regulation spans 1:5000, and a small-signal bandwidth of 400 Hz keeps the following error low in high-dynamic axes. The internal brake relay engages within 6.5 ms, limiting mechanical overrun. Differential ±2.0 VDC references are accepted for velocity and torque commands. A velocity monitor outputs 2.0 V for every 1000 rpm so supervisory controls can verify the actual shaft speed. The broad regulation range supports both slow indexing moves and rapid traverses on the same machine axis.

A dedicated regeneration path routes excess energy to a 100 Ω resistor that can dissipate 20 W continuously. The brake circuit absorbs up to 360 J per event and supports 10 operations per hour without thermal saturation. Because the regeneration hardware is built in, external dumping assemblies can often be omitted, reducing wiring requirements. Cabinet installation is simplified by a mass of 2.2 kg. Drive protection is coordinated through a current-limit channel that responds to a ±2.0 VDC analog limit request, while a feedback port providing 2.0 V per rated ampere allows real-time phase current observation. These analog paths support rapid torque limiting while keeping regenerative operation within safe thermal limits.
