Product Description:

The SCE905AN-002-01 is a servo drive produced by Pacific Scientific for the SCE900 Servo Drives series. In an automation cell, it functions as the power stage between a motion controller and a brushless servo motor, regulating phase current to achieve commanded position, speed, or torque. The unit shares a common form factor and parameter structure with companion drives in the series, which helps keep cabinet layouts and control integration consistent when different axis ratings are used in the same machine. It can be used for positioning axes, indexing stations, and other servo-controlled machine functions that require stable current regulation.

The drive delivers a continuous output capability of 15.9 A at 25 °C and can supply up to 31.8 A for short overload intervals, giving machines added current for acceleration or disturbance rejection. Thermal management relies on a convection-cooled chassis with no forced-air fan, so the cooling path has no moving parts. Command signals are accepted through a programmable interface that supports analog or incremental digital command formats, allowing the same unit to follow ±10 V velocity loops or step-and-direction pulse streams from a PLC. This control flexibility allows the drive to work with different motion architectures without requiring a separate hardware version for each command method.

The housing depth is 229 mm, the overall height is 370 mm, and the width is 160 mm, enabling side-by-side mounting in 300 mm deep enclosures while still leaving air passages for passive heat dissipation. The drive weighs 9.5 kg, which gives the enclosure useful thermal mass without making the unit excessively bulky in the cabinet. The enclosure size also leaves room for cable routing and spacing between adjacent units in multi-axis panels where several drives are installed together. Passive cooling works best when space around the housing remains open for airflow along the chassis surfaces.
