Product Description:
The SC9020010104G108 is a servo drive produced by Pacific Scientific and supplied in the SC900 Servo Drives series. The unit accepts three-phase mains power and delivers controlled current to matched permanent-magnet or induction servomotors for closed-loop speed and position control in packaging lines, pick-and-place systems, and similar equipment. Its panel-mount enclosure uses convection cooling, so it fits standard control cabinets without external blowers or coolant connections. This arrangement supports compact installations where accurate axis response is needed from a cabinet-mounted amplifier. Because cooling is passive, airflow planning remains simple as long as normal clearance is maintained around the enclosure.
The drive uses an analog or incremental digital control interface, allowing either ±10 V velocity commands or quadrature step-and-direction inputs from a motion controller. Under natural convection at 25 °C, the power stage supplies a continuous output current of 3.75 A, which corresponds to 1.1 kW of mechanical shaft power when operated from a 240 V three-phase source. For short acceleration demands, the amplifier can provide a peak current of 7.5 A and up to 2.2 kW in brief bursts. Overall conversion efficiency reaches 95%, which helps limit heat generation inside the cabinet. The same control approach also suits retrofit machines that already use analog reference wiring or pulse inputs from an existing controller.
Motor selection must respect the published inductance requirement. Stable operation requires motor windings with line-to-line inductance of at least 4.0 mH; values outside the supported range can cause overcurrent trips or reduce current-loop response. The drive does not include a network interface, so status information is shown by front-panel LEDs and parameter retention is handled by onboard EEPROM. Local trim potentiometers are used for setup and tuning, which makes the unit suitable for small gantry axes and retrofit applications that rely on direct local control.
