Before operation
4.3.5 Limit the maximum and minimum output frequency (Pr. 1, Pr. 2)
Motor speed can be limited.
Parameter
Number
Name Initial Value Setting Range Description
1 Maximum frequency
120Hz 0 to 120Hz Set the upper limit of the output frequency.
2 Minimum frequency
0Hz 0 to 120Hz Set the lower limit of the output frequency.
Changing example
Limit the frequency set by the potentiometer,
etc. to 60Hz maximum.
(Set "60"Hz in Pr. 1 Maximum frequency.)
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 the Instruction Manual (Applied).)
CAUTION
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
frequency.
