Product Description:
The SC104-001-M brushless servo controller is manufactured by Pacific Scientific and belongs to the SC100 Brushless Servo Controllers series. It is a closed-loop drive intended to supply commutation, current, and velocity control to brushless servo motors used in industrial automation, robotics, and material-handling axes. By regulating armature current from a DC bus, the controller converts three-phase mains power into a form suitable for fast torque response and precise positioning tasks common on assembly lines, packaging stations, and semiconductor tools.
At the heart of the unit is a nominal bus voltage of 320 VDC that stores energy for the power stage. Under continuous stall conditions, the amplifier can deliver up to 20 A of phase current, translating into a sustained mechanical output of 6 kW from the connected motor. The internal shunt regulator dissipates regenerated energy and is rated for 30 W continuously, preventing overvoltage when loads decelerate. Overall conversion efficiency exceeds 95%, so most of the drawn power reaches the motor rather than being lost as heat. Power dissipation at full load is limited to 130 W, which helps keep enclosure temperatures within the 0 °C to 50 °C operating range.
The power section accepts a three-phase supply of 230 VAC (+10%, −15%) at 47–63 Hz, matching the distribution networks found in most industrial facilities. During rapid acceleration, the controller can source 60 A for up to five seconds, allowing short bursts of mechanical output that peak at 17 kW. Excess kinetic energy from aggressive deceleration is absorbed by the shunt circuit, which can handle 15 kW for 300 ms. The PWM bridge switches at 5 kHz, balancing current ripple and electromagnetic interference. The controller uses three input phases, carries a standard customization code, and can be stored at temperatures from −55 °C to 70 °C.
