6.6.1 Basic Settings for Position Control
This section describes the reference pulse forms and input filters.
Reference Pulse Forms
To perform speed control, you must specify how the reference is input from the host controller
(i.e., the reference pulse form). You set the reference pulse form in Pn200 (Position Control Ref-
erence Form Selections).
