initial values in the following cases :
(I) The set values of input terminal function selection 1,2 and 3 (nO6, n07 and nO8) are the
same.
(2) If the following conditions are not satisfied in the torque pattern_setting(V/f pattern setting) :
Max. output frequency (n24) > Max. voltage output frequency (n26)
> Mid. output frequency (n27)
> Min. output frequency (n29)
For details, refer to "Adjusting torque according Io application" (V/f pattern setting) on page
51.
(3) If the following condilions are not satisfied in the Jump frequency setting :
Jump frequency 3 (n58) < Jump frequency 2 (n57)
< Jump frequency I (n56)
(4) If Frequency reference lower limit'(n42) < Frequency reference upper limit (n41)
