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.
