Parker Hannifin 591S035091100 Digital Servo Drive

The Parker Hannifin 591S035091100 Digital Servo Drive is a Parker SSD Drives DC servo drive in the 590/591 family, engineered for precise digital control of DC motors in automated systems. This model carries the 591S designation and aligns with Parker’s three-phase (3PH) digital drive configurations in the 590-series lineup. The 591S family spans current ratings from 35 A up to 270 A, and is available in two-quadrant (non-regenerative) and four-quadrant (regenerative) variants, reflecting Parker’s thyristor-based power assemblies. Spare power boards such as AH385851U003-1 are used across 591S DC Drives (and other 591 variants like 591C, 591L, and 591A) in current sizes of 35 A, 70 A, 110 A, 150 A, 180 A, and 270 A. The 591S035091100 unit, as part of the SSD Drives DC family, is designed to deliver controlled torque and speed to DC servo motors with Parker SSD’s digital control approach, suitable for automation applications requiring reliable servo performance and integrated drive support.
