DATA USED FOR POSITIONING CONTROL
* 1 Setting unit (pulse unit) for speed setting data changes according to the value set to "
limit value" as the table below.
Setting value
Pr.4
of "Speed limit value"
(pulse/s)
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 speed setting parameter and data.
If setting a value that does not satisfy the condition, the value is dropped so that it can be multiples of
25. Note if setting a value under 25, corresponding to pulse unit, an error occurs.

If 65090 is set to speed setting parameter or data, it is dropped to 65075, multiples of 25.
* 2 Set ACC/DEC time at OPR within the range that the following formula is satisfied. If the
Pr.15
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.)
