01: Same direction as the forward/reverse RUN signal
10: Fixed rotation direction
11: Automatically selected rotation direction
S Bit 2: Selection for fixed rotation direction
0: Forward rotation of load shaft
1: Reverse rotation of load shaft
S Bit 3: Stop position reference code
0: 12-bit binary
1: 3-digit BCD
