Product Description:
The SC453-016-05 is a brushless servo controller manufactured by Pacific Scientific for the SC450 Brushless Servo Controllers series. It operates as a programmable digital position controller that manages torque, speed, and position loops for industrial servomotors. Motion routines are written in PacSci ServoBASIC and run inside the unit, so indexed moves and sequence control can be handled locally instead of relying on a separate external controller. This arrangement keeps motion logic close to the power stage and supports standalone axis control in automated equipment. Resolver feedback from the motor supplies absolute shaft data, allowing the position loop to close at power-up without a homing cycle.
This model draws a continuous phase current of 7.5 A from either 115 VAC or 230 VAC lines, so the drive keeps the same continuous current capability on both supply voltages. Transient load events can be handled with a peak output of 15.0 A for rapid acceleration and short bursts of higher torque. Internal pulse-width modulation operates at 15 kHz, which helps smooth motor current and keeps switching noise above most audible ranges. When powered from 230 VAC, the drive can deliver up to 4500 W to the motor, supporting mid-range servo axes in packaging equipment, electronics machinery, and test stands. Position data are quantized at 4096 steps per rev, so small commanded moves can be repeated with consistent angular increments. Program storage is internal, allowing motion parameters and control routines to remain in the controller after they are downloaded.
Accuracy and temperature limits set the operating range of the controller during use and storage. Positional error is limited to 15 arcmin, which suits pick-and-place tooling and moderate-precision indexing applications. The command register spans 0 to +100,000,000 steps, allowing long travel commands without counter rollover during extended motion sequences. The wide command range is useful for long indexing tables, feed systems, and other axes that accumulate large position counts during normal operation. The electronics operate from 0 to 50 °C, and the unit can be stored unplugged from -55 to 70 °C without damage to internal components. Its approximate weight of 5.0 kg supports panel mounting and provides a solid enclosure for industrial installation.
