REMARKS
· The output frequency is clamped by the Pr. 2 setting even if the set frequency is lower than the Pr. 2 setting (The frequency will
not decrease to the Pr. 2 setting.)
Note that Pr. 15 Jog frequency has higher priority than the minimum frequency.
· When the Pr. 1 setting is changed, frequency higher than the Pr. 1 setting can not be set by
· When performing a high speed operation at 120Hz or more, setting of Pr. 18 High speed maximum frequency is necessary.
(Refer to chapter 4 of
If the Pr. 2 setting is higher than the Pr. 13 Starting frequency value, note that the motor will run at the set frequency
according to the acceleration time setting by merely switching the start signal on, without entry of the command
