The following functions are available for continuous rotation.
For continuous rotation, select the model with the following formula.
Rotation speed : N (rpm)
Cycle time : t

In the example, the shaft accelerates at acceleration time: ta to set
speed: N, and when a continuous rotation stop is input, stops with
deceleration time: td.
: Continuously rotates at a set speed until the
continuous rotation stop signal is input.
: If used with equal division designation,
stops at an equal division when the
continuous rotation stop signal is input.
: If used with equal division designation, the
timing output pulse is output at the equal
division during rotation.
