The document provides specifications for the S60A40AC analog servo drive. It is designed to drive 3-phase brushless motors with sinusoidal current at high switching frequencies. The drive requires two 120-degree phase shifted sine wave command signals for motor control. It has over-current, over-voltage and short circuit protections. Key features include 4-quadrant regenerative operation, adjustable current limits and a built-in brake/shunt regulator.
