Product Description:
The SC453-016-02 is a brushless servo controller from Pacific Scientific in the SC450 Brushless Servo Controllers series. It is a programmable digital position controller intended for closed-loop motion axes where coordinated speed and position control are required in industrial automation cells, conveyor indexers, and pick-and-place stations. By interpreting resolver feedback from a connected motor, the unit adjusts current and voltage so the motor shaft reaches and maintains commanded positions.
For continuous operation from either 115 VAC or 230 VAC mains, the controller supplies up to 7.5 A of phase current, which is the thermal limit it can hold indefinitely without exceeding component temperatures. During fast accelerations, it can deliver a peak of 15.0 A, permitting short bursts of torque before an overload trip occurs. When powered from a 230 VAC source, the drive can return up to 4500 W to the motor, matching medium-frame brushless servos used on packaging or assembly lines. Its power stage switches at 15 kHz, a carrier frequency chosen to lower audible noise while keeping switching losses manageable. Commanded motion is quantized at 4096 steps per rev, giving the internal processor enough granularity for smooth interpolation without overloading memory resources.
The position loop closes with an accuracy of 15 arcmin, allowing repeatable placement of parts or tooling within typical mechanical tolerances. Programmed moves may span 0 to +100,000,000 steps, so both fine indexing and very long travels are supported from the same device. Reliable service is permitted in ambient temperatures from 0 to 50 °C, because beyond that range the heat sink cannot dissipate losses quickly enough. When not in operation, the electronic components withstand temperatures from -55 to 70 °C without performance drift, and the enclosure, cabling, and connectors bring the total mass to 5.0 kg, which is manageable for panel or machine-side mounting.
