Position Control Mode in Servo Motors<\/strong><\/h2>\n\n

Servo Motor<\/strong><\/a>,<\/strong> In position control mode, the speed proportional gain parameter must be increased until vibration begins. Generally, a high speed gain value must be entered for high inertia. This parameter reduces start-up, stop, and road vibrations. <\/p>\n\n

The speed integral time constant of the servo motor<\/strong> must be reduced until vibration begins. This parameter improves surface machining quality in CNC routers. <\/p>\n\n

The position feedforward gain should be set to 0%. The position proportional gain should be set as high as possible within the range where the servo motor <\/strong>is stable. If it is increased excessively, the position capture values will increase. The line characteristic improves, delay errors are minimized, but vibration may start during stopping. <\/p>\n\n

\u25e6Servo Motor:<\/strong> If high precision is required on surface lines, the position feedforward gain can be increased. If it is set too high, malfunctions may occur. Servo Motor<\/strong> position gain parameter values can be used as follows. <\/p>\n\n

Experimental Parameter Values in Servo Motors<\/strong><\/strong><\/p>\n\n

The factory setting for parameter 5 is 150. It can be increased from 150 to 260. If the vibration persists, parameter 6 can be increased up to 140. <\/p>\n\n

A suitable value for Parameter 6 is between 15 and 60. It should be lowered as much as possible. The factory default value is 20. <\/p>\n\n

Parameter 9 is the last PID parameter to be set. The Servo Motor <\/strong>Parameter 9 setting should be increased as much as possible. The range value is 40 ~ 330. <\/p>\n\n
