Full-Closed Control
The full-closed control function is used to read the position feedback signals from a linear encoder and
various encoders on the load side. You can configure the desired system and carry out precision
position control without being affected by mechanical system errors. Basically, the full-closed control
system uses the external position sensor on the load side to carry out position control. The motor-side
encoder is used for velocity control. A dual feedback control system, which combines the full-closed
control and semi-closed control, can provide a faster response by using the position data of the high-
speed rotating motor encoder and the load-side external encoder.
