Product Description:

The RS1A15AE0 servo amplifier is produced by Sanyo Denki for the R SANMOTION Servo Drives series. As a closed-loop power stage, it modulates the energy fed to a matched servo motor so that factory controllers can execute accurate velocity and position commands without mechanical throttling. By integrating the drive into a motion axis, users obtain electronic deceleration, rapid reversals, and fine speed tracking that are essential in pick-and-place robots, CNC work cells, and high-speed conveyors.

Electrical performance centers on an output capacity of 150 A, delivered through an IGBT PWM sinusoidal control system that reduces torque ripple at the shaft. Excess kinetic energy is handled by a built-in regenerative resistor rated at 6 Ω, supported by an internal regeneration process that eliminates the need for external braking hardware. The control circuitry operates from a single-phase source, while the main power section connects to a three-phase supply, separating logic and motor currents for improved noise immunity. Frequency response reaches 600 Hz (JL=JM), enabling high-bandwidth speed loops, and the drive maintains a 1:5000 speed control range for applications that move between slow feeds and rapid traverses. Safety provisions include a built-in dynamic brake and a leakage current of 3.0 mA per motor, keeping touch currents below commonly accepted limits.

The compact enclosure measures 240.5 mm deep, 235 mm high, and 125 mm wide. The housing weighs 6.5 kg, easing panel layout and installation handling. A tray-type power supply structure is incorporated, so additional bulkhead components are unnecessary. Four mounting holes, each with a diameter of 6 mm, secure the unit against vibration. The enclosure proportions also leave room for routing motor, power, and control conductors within a multi-axis automation cabinet.
