Precautions for Correct UsePrecautions for Correct Use
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.
The internal speed command controls the motor speed according to the internal speed command value
set in the parameter.
The internally set speed is enabled when Command Speed Selection (Pn300) is set to 1 or 3.
Up to eight internally set speeds can be set.
