Operating Functions
Selecting the Internally Set Speeds
The four internally set speeds are switched by using the Internally Set Speed Selection 1 Input
(VSEL1) and Internally Set Speed Selection 2 Input (VSEL2).
Operation
Note If more than one internally set speed selection signal is switched at the same time (e.g., as
when switching from Speed 2 to Speed 3), an internally set speed signal in the process of
switching may be temporarily selected. (For example, Speed 1 or Speed 4 may be
temporarily selected.)
The internally set speed command may be temporarily performed with a sudden change,
especially if the acceleration or deceleration time is set to 0 or small value, or if the speed
difference between internally set speed commands is large. Use this function with the
following precautions.
 Avoid switching more than one internally set speed selection signal at the same time.
 Set both Soft Start Acceleration Time and Soft Start Deceleration Time so that the speed
changes gradually and avoid a sudden change.
