5-2 Speed Control

5-2 Speed Control
Outline of Operation
 Motor speed control is performed based on the analog voltage input from the controller.
You can also perform position control by combining with a controller that has a position control
function.
 You can change the relation between the speed command and the rotation speed by setting the
Speed Command Scale (Pn302).
