5-4 Internally Set Speed Control
Operation Example
 Internally set speed control with 4 speed changes when Pn300 = 1
*1. The acceleration time, deceleration time, and S-curve acceleration/deceleration time can be set using
5
If more than one internally set speed selection signals are changed at the same time (e.g., as
when changing from speed 2 to speed 3), the internally set speed selection signals between
them may be temporarily selected. (For example, speed 1 or speed 4 may be temporarily
selected.)
Observe the following precautions if an acceleration time or deceleration time of 0 or close to
0 is used, if the sign of the internally set speed command changes, or if the change in the
internally set speed command is large. Any of these may cause a sudden change in the
internally set speed command.
1) Do not change between more than one internally set speed signal at the same time.
2) Set soft start acceleration and soft start deceleration and change the speed gradually (i.e.,
