■ EXAMPLE 4
Condition:
Make 3th axis motor move -120(steps) from right now position, ID = 3.
Method:
-120 = 0x88 = 0xff88 < -63,Two byte data.
0xff88 = 0x1111 1111 1000 1000:
Lower 7bits = 000 1000 = 0x08 Higher 7bits = 0111 1111 = 0x7f
Use function Go_Relative_Pos(=0x03), Packet Length = 5.
B4 = 0x03;
B3 = 0x80 +(PacketLength-4)*32 + Go_Relative_Pos = 0x80 +0x04 =0xa3.
B2 = 0x80 + 0x7f = 0xff
B1 = 0x80 + 0x08 = 0x88
S = B4 + B3 + B2 + B1 = 0x03 + 0xa3 + 0xff + 0x88 = 0x22d
B0 = 0x80 + Mod(S , 128) = 0x80 + 0x2d = 0xad
■ EXAMPLE 5
Condition:
Make 2th axis motor turn at 60rpm, ID = 2.
Method:
Speed is 60, One Byte data is enough, 60 = 0x3c. Packet Length = 4.
B3 = 0x02;
B2 = 0x80 +(PacketLength-4)*32 + Turn_ConstSpeed = 0x80 + 0x0a = 0x8a
B1 = 0x80 + 0x3c = 0xbc
S = B3 + B2 + B1 = 0x02 + 0x8a + 0xbc
B0 = 0x80 + Mod(S , 128) = 0xc8
■ EXAMPLE 6
Condition:
Make 2th axis motor turn at -60rpm, ID = 2. Speed is -60 = 0xc4 = 0x1100 0100 > -63, One byte data 7bits =
0x0100 0100 = 0x44. Packet Length = 4.
Method:
B3 = 0x02;
B2 = 0x80 +(PacketLength-4)*32 + Turn_ConstSpeed = 0x80+0x40+0x0a = 0x8a
B1 = 0x80 + 0x44 = 0xc4
S = B3 + B2 + B1 = 0x02 + 0x8a + 0xc4 = 0x150
B0 = 0x80 + Mod(S , 128) = 0x80 + 0x50 = 0xd0
