Pulse unit 1-pulse unit
When setting " Speed limit value" to 100000 (pulse/s) (when pulse unit is 25-pulse unit), set a
Pr.4
value which is "multiples of 25" to "
If setting a value that does not satisfy the condition, the value is dropped so that it can be multiples
of 25.
* 2: Set ACC/DEC time at speed change within the range that the following formula is satisfied. If

the condition is not satisfied, "Out of ACC/DEC time setting valid range"warning (warning code: 26)
occurs, and control is performed in the time between the maximum value and the minimum value
calculated by the following formula. (Refer to "Example" below.)
