@@@@A remember function test system of DC-motor drive assembly unit based on ripple counter technology was presented. When assembly unit was clamped,the high-power DC power supply was adopted to supply power to DC-motors by contactor. On/off of the contactor and the direction of motor’s current were controlled by PLC,so assembly unit could run forward or backward. The cur-rent signal of DC-motor was collected by AD card in the rotation process,then it was processed by using digital filter and FFT technol-ogy. The test results were compared with prescribed parameter. The experimental results show that the system frequency measure pre-cision is in the range of ± 10 Hz,and the test system can steady run in a long time.
