Product Description:
The SC722A-001-PM72012 is a servo controller in the SC720 Command Controllers series manufactured by Pacific Scientific. As a torque and velocity controller, it regulates motor current and speed in automated machinery, translating analog velocity commands into PWM-driven power for brushless servomotors and providing closed-loop stability for positioning tasks on assembly lines, packaging stations, or material-handling axes. The unit weighs 13 lbs, so panel mounting does not require heavy reinforcement in standard control enclosures.
During operation, the controller can supply a continuous phase current of 3.8 A and withstand short bursts up to 7.5 A. When powered from a 240 Vac three-phase line, the internal bus rises to 320 Vdc, allowing a continuous output of 1.1 kW and momentary peaks of 2.2 kW. The 160 Vdc bus produced from a 120 Vac source enables the same current but lowers mechanical power for lighter loads. Resolver feedback is processed by a 12-bit RDC and a 1024 ppr encoder emulator, delivering position signals to the drive and to external controls. Motor speed is tracked through that emulated channel, while the analog monitor port presents 0.63 V for every ampere of phase current. System diagnostics are exported through a 3-bit open-collector fault bus, and the built-in resistor absorbs 20 W of regenerated energy during standard operation.
Dynamic characteristics are shaped by the switching stage that modulates at 20 kHz, keeping ripple outside most servo bandwidths and reducing audible noise. At the command interface, the controller accepts a velocity signal of ±10 V, converting it to torque with an accuracy of ±22 arcmin when resolver alignment is correct. During aggressive deceleration, excess bus energy is routed to the braking resistor, which tolerates peaks of 3 kW. Load inertia and duty cycle must remain within the controller's electrical and thermal limits during operation.
