Product Description:
Pacific Scientific builds the SC403-013-T3 servo drive as part of the SC400 Servo Drives series for closed-loop motion control in industrial automation. The drive accepts 115 or 230 VAC mains and outputs three-phase power to a matched brushless motor, regulating velocity through tachsyn feedback and an analog command. By converting fixed-frequency line power into variable voltage and frequency, the unit lets PLCs and CNC controllers position axes precisely in packaging, printing, or material-handling equipment.
During steady operation, the power section supplies a continuous phase current of 7.5 A, allowing motors to deliver rated torque without overheating. With a 230 VAC three-phase line, the converter can sustain 2250 W of mechanical output, while its rectifier working from a 115 VAC source charges the DC link to 160 VDC. The pulse-width-modulated stage runs at an output ripple frequency of 15 kHz, a switching rate chosen to reduce audible noise and smooth current waveforms. Speed is commanded through a differential analog input that accepts ±10 V, so external controllers can modulate velocity with minimal signal conditioning. Additional connections on a 0.100 in signal header carry tachsyn, enable, and fault lines, and the tachsyn channel expects a gradient of 2.0 V/Krpm for proper velocity scaling.
The high-demand portion of each cycle is supported by a peak bus capability of 320 VDC on the 230 VAC input, producing up to 15 A of output for short bursts and a corresponding mechanical limit of 4500 W. A fault transistor can sink 25 mA at 30 VDC to report overtemperature, overcurrent, or loss of feedback to upstream safety relays. Auxiliary electronics draw no more than 10 mA, easing loading on control supplies. Power wiring lands on a header with a pitch of 0.156 in, while the drive's 4.5 in width helps conserve panel space and supports high rack density.
