Working Principle
The Parker AR-08AE-14293 operates as a closed-loop digital servo drive controlling the position, velocity, or torque of a connected servo motor. The drive receives AC input power (120/240 VAC) which is rectified to a DC bus voltage (170/340 VDC) by an internal rectifier and filtered by DC link capacitors. The digital signal processor (DSP) executes servo control algorithms at a 62.5 microsecond update rate, processing feedback from the motor’s encoder or resolver to determine the motor’s actual position, velocity, and current.
