The HCS mode shortens the communication time of the signal which has been compressed. KR-415FHD can change a mode to each channel 1-4 indiviually. HCS is a communication method to largely improve linearity of the servo movement. When using HCS mode, correspondence servos(ex, RSx3/BSx3series)are required. The correspondence servo recognizes both modes automatically.
