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
EX-RR / EX-1(KIY) / EX-2(KIY) / Esprit4 / EX-5FH / RF-904FH / RF-903FH
