6.2 Position control mode
Position control is the most important and commonly used control mode of the servo system.
Position control refers to controlling the position of the motor through position instructions, and
determining the target position of the motor by the total number of position instructions. The
frequency of the position instruction determines the motor rotation speed. The servo drive can
achieve fast and accurate control of the position and speed of the machine. Therefore, the position
control mode is mainly used for occasions that require positioning control, such as manipulators,
mounter, engraving machines, CNC machine tools, etc. The position control block diagram is shown
in Figure 6-6.
