Product Description:
The SC101-001-T2 is a brushless servo controller built by Pacific Scientific for the SC100 Brushless Servo Controllers series. It is supplied in a standard controller configuration and is intended for industrial automation systems that use permanent-magnet servo motors. A Tachsyn Processor interface reads tachometer feedback so the controller can regulate torque and speed with closed-loop control. This arrangement supports stable axis motion in machinery that depends on repeatable response during speed changes and load variation.
This model accepts a single-phase input of 230 VAC (+10%, -15%) at 47–63 Hz and internally produces a 320 VDC bus for power conversion. Under continuous stall conditions, the drive delivers 7.5 A of output current, which corresponds to 1.5 kW of motor output while dissipating 60 W as heat inside the enclosure. Efficiency remains above 95%, so most of the drawn energy is transferred to the load rather than lost thermally. The converter switches at 5 kHz, which helps limit current ripple during normal operation. Regulation accuracy is supported by a tachometer gradient of 1.0 V/Krpm, and the unit is intended to operate in ambient temperatures from 0 °C to 50 °C.
For brief overloads, the unit can supply 15 A of current and as much as 4 kW of power for five seconds, enabling acceleration or recovery from short shock loads without additional hardware. Energy returned during deceleration is handled by the shunt regulator, which absorbs 30 W continuously and up to 8 kW for 300 ms to protect the DC bus from overvoltage. This allows the controller to handle short braking events without relying on an external dissipation device for every deceleration cycle. Long-term storage is permissible between -55 °C and 70 °C without deterioration of components or calibration.
