*1. The acceleration time, deceleration time, and S-curve acceleration/deceleration time can be set
using parameters (Pn58, Pn59, and Pn5A).
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.
