Product Description:
The RS2A01A0AL0SAL is a servo amplifier manufactured by Sanyo Denki for the R SANMOTION Servo Drives series. It serves as the power stage between a motion controller and a servomotor, converting fixed-frequency factory power into a modulated output that drives the machine axis. By closing the speed and torque loops electronically, the unit supports repeatable positioning and rapid cycle times in general industrial automation. This control structure allows the connected axis to respond accurately to changing motion commands and operating loads.
The amplifier has a continuous phase-current capacity of 15 A, making it suitable for medium-frame rotary servomotors used in feeders or indexing tables. During power-up, the control electronics briefly draw an inrush current of 40 A, while the main power stage experiences a separate 18 A surge, so upstream protection must tolerate both transients. Regulation is handled by an IGBT pulse-width modulation sinusoidal drive scheme that limits harmonic distortion while providing a frequency response of 600 Hz. The input section accepts three-phase AC 200 V power, allowing direct connection to common factory supplies without a transformer. The speed loop maintains control across a 1:5000 range, supporting slow indexing and high-speed travel with the same motor. These operating characteristics allow the amplifier to control speed over a broad range while maintaining responsive current regulation.
Leakage current is limited to 0.5 mA, so the chassis can be connected through standard grounding conductors without exceeding touch-current thresholds. A built-in dynamic brake dissipates regenerative energy during rapid stops, while the internal regeneration circuit manages moderate DC-bus overvoltage without requiring an external resistor. Despite these functions, the housing weighs only 0.9 kg, which reduces the load placed on lightweight mounting panels. The assembly withstands shocks up to 2G, allowing it to tolerate mechanical forces encountered during handling or use on mobile gantries. Motor feedback is received through a serial encoder, and no external encoder input is provided. This arrangement reduces feedback wiring and ensures that speed and position data originate from the connected motor.
