Product Description:
The SC102-001-T4 is a brushless servo controller manufactured by Pacific Scientific for the SC100 Brushless Servo Controllers series. As a standard controller, it regulates torque, velocity, and position for industrial automation systems that use permanent-magnet servomotors on indexing tables, conveyors, and other controlled axes. The unit is intended for panel mounting inside multi-axis machinery, where centralized placement keeps power wiring and feedback routing organized. Motor feedback is handled through a built-in Tachsyn processor interface, allowing the control loop to respond accurately to commanded motion changes.
The power section is built around a nominal bus of 320 VDC and supports a continuous stall current of 12 A, which corresponds to 3.6 kW of sustained mechanical output. Under rated load, the converter dissipates 90 W and operates at greater than 95% efficiency, which helps limit waste heat during continuous operation. The mains connection accepts three-phase 230 VAC input within ±10%/-15%, so the controller can run from common industrial supplies, and the switching stage runs at 5 kHz to reduce ripple. A tachometer gradient of 4.0 V/Krpm linearizes motor speed feedback, while full performance is maintained across an ambient range of 0 °C to 50 °C. The internal shunt circuit can absorb 30 W continuously during overvoltage events on the bus.
For short-duty operation, the drive can source 15 A for up to five seconds and deliver a peak shaft power of 4.5 kW during inertial starts or rapid indexing. This short-term current reserve supports brief acceleration demands without requiring the controller to remain at peak load continuously. During these surges, the shunt regulator can withstand 8 kW for 300 ms, which helps prevent DC link rise when regenerative energy returns to the bus. For storage or transport, the electronics tolerate -55 °C to 70 °C without degradation, and three-phase wiring simplifies installation across distributed motion nodes.
