Product Description:

The SCE904-001-01 is an AC servo drive from Pacific Scientific and belongs to the SCE900 Servo Drives series. Acting as the power stage in a closed-loop axis, it converts low-level control signals into three-phase motor current so that position, speed, and torque remain within commanded limits. In automated packaging lines, pick-and-place gantries, and indexing tables, the unit provides the regulated energy flow between the motion controller and the mechanical load. This operating role makes it suitable for motion systems that require stable axis control during repeated start, stop, and speed-change cycles.

At an ambient temperature of 25 °C, the drive delivers a continuous output of 10.6 A, which represents its steady operating current. For acceleration bursts, it can rise to 21.2 A to provide additional torque during rapid motion changes. Command information reaches the power stage through Analog or Incremental Digital Command channels, allowing the same unit to accept either analog velocity references or incremental digital control signals. The drive is part of the 900 Series, which includes models with similar connector layouts and control functions. With a width of 114 mm, multiple axes can be arranged side by side while still leaving space for cable routing and airflow.

The enclosure stands 370 mm tall and extends 229 mm deep, which helps it fit standard cabinet back panels without excessive projection toward the door. A mass of 6.6 kg keeps mounting loads moderate during installation and supports use in multi-axis control cabinets. Its Servo Drive classification indicates that the housing contains internal bus capacitors, reducing the need for separate upstream power conversion hardware in many motion-control layouts. The enclosure size also supports orderly spacing around adjacent components so cooling air and power wiring can be managed without crowding the cabinet interior.
