* 1. Setting ranges when the maximum frequency (E1-04) is set to 400 Hz and the frequency ref-
erence upper limit (d2-01) is set to 110%.
* 2. Set the number of motor poles to o1-03 (Frequency units of reference setting and monitor).
Output frequency (F) is output in [reference setting (r/min
* 3. Setting example of o1-03
If setting 12000 to o1-03, reference input at 100% is 2000 and monitor display is 200.0.

• Upper limit for setting range ≤ the maximum frequency (E1-04) ≤ the frequency reference upper limit
(d2-01).
• Lower limit for setting range ≥ the minimum frequency (E1-09) ≥ the frequency reference lower limit
(d2-02).
• For BCD inputs, most upper digit can be set from 0 to 15.
