Product Description:
The SC402-017-T4 is a digital servo drive manufactured by Pacific Scientific and supplied as part of the SC400 Servo Drives series. It accepts single- or three-phase mains power, creates a regulated DC bus, and generates pulse-width-modulated output for brushless motors. The drive interfaces directly with tachometer feedback and provides closed-loop velocity control for precise positioning tasks in automated assembly lines. By processing ±10 V velocity commands from upstream controllers, it acts as the power stage that links low-power control logic with mechanical motion, ensuring repeatable speed regulation and a quick response to load changes.
The internal bus reaches 160 VDC when the supply is 115 VAC and rises to 320 VDC with a 230 VAC source, so the output stage has consistent headroom across common plant voltages. A continuous output capability of 3.50 A supports steady operation without thermal derating, while a peak rating of 7.0 A provides short bursts of torque for acceleration or disturbance rejection. These currents are switched at an output ripple frequency of 20 kHz, which helps minimize audible noise and reduce motor current ripple. The velocity input command spans ±10 V and maps linearly to full motor speed, simplifying the analog interface with an upstream controller.
For power delivery, the drive sustains 1000 W on a 230 VAC three-phase line and can momentarily increase its output to 2000 W during peak events such as rapid indexing. Diagnostic circuitry provides a fault output that can sink up to 25 mA at a maximum of 30 VDC, allowing direct connection to indicator lamps or PLC status inputs without additional relays. Motor speed feedback is scaled by a tachsyn gradient of 4.0 V per krpm, supplying the control loop with a proportional voltage that simplifies calibration. This feedback signal allows the drive to detect velocity deviations and adjust motor current as operating loads change.
