When the CNC lathe spindle is operating at high speed for cutting, the Siemens 6SL3246-0BA22-1FA0 unit we Buy runs extremely stably, with low ripple in the DC bus power supply. The interface of this batch of Quanzhou Xin Yuan Technology products is closely matched. Compared with the old modules, the actual measured heat dissipation efficiency has increased, the temperature rise of the motor has significantly decreased, and the positioning accuracy is more accurate.
