DYNAMIXEL
AX-12
4-6. SYNC WRITE
Function Used for controlling many Dynamixel actuators at the same time. The communication
time decreases by the Synch Write instruction since many instructions can be
transmitted by a single instruction. However, you can use this instruction only when the
lengths and addresses of the control table to be written to are the same. Also, the
broadcasting ID needs to be used for transmitting.
ID 0XFE
Length (L + 1) * N + 4 (L: Data length for each Dynamixel actuator, N: The number of Dynamixel
actuators)
