Product Description:

The SC102-001-T2 brushless servo controller is manufactured by Pacific Scientific within the SC100 Brushless Servo Controllers series. The unit sits between the three-phase supply and a permanent-magnet motor, converting line power into a regulated DC bus and pulse-width-modulated phase currents so that automated equipment receives consistent torque and rapid dynamic response. It fits motion loops that rely on velocity feedback to position loads in conveyors, gantries, or indexing tables. Its control approach supports steady speed regulation and quick response when the commanded load changes.

A normal bus voltage of 320 VDC is maintained by the internal power section, and this level is produced from a line input of 230 VAC (+10%, -15%) supplied by a three-phase network operating at 47 to 63 Hz. With the bus energized, the drive can source a continuous armature current of 12 A and support motor output up to 3.6 kW while sustaining efficiency above 95%. During steady operation, it removes 30 W through the shunt regulator and dissipates 90 W as heat in its electronics. The Tachsyn Processor interface reads a 1.0 V/Krpm tachometer gradient to close the speed loop, which allows the controller to respond directly to motor speed feedback.

For transient demands, the controller raises output to a 15 A peak for five seconds, enabling up to 4.5 kW of burst power before duty returns to nominal. These surges are absorbed by the bus capacitor, while the shunt circuit can momentarily sink 8 kW in 300 ms to limit overvoltage. The internal inverter operates at a 5 kHz carrier, which helps smooth motor torque while balancing switching losses. Full ratings are supported from 0 °C to 50 °C, and the unit can be stored between -55 °C and 70 °C without degradation. Short-term overload capacity helps the drive handle acceleration phases and brief load spikes without interrupting normal control.
