F20 [Jog
frequency]
0/400
[Hz]
 This parameter sets the
frequency for Jog operation.
 It cannot be set above F21 –
[Max frequency].
10.0 O
F21 [Max
frequency]
40/400 *
[Hz]
 This parameter sets the
highest frequency the inverter
can output.
 It is frequency reference for
Accel / Decel (See H70)
 If H40 is set to 3(Sensorless
vector), it can be settable up to
300Hz *.
60.0 X
☞
Caution : Any frequency
cannot be set above Max
frequency.
F22 [Base
frequency]
30/400
[Hz]
 The inverter outputs its
rated voltage to the motor at
this frequency (see motor
nameplate). In case of using a
50Hz motor, set this to 50Hz.
60.0 X
F23 [Start
frequency]
0.1/10
[Hz]
 The inverter starts to output
its voltage at this frequency.

It is the frequency low limit.
0.5 X
F24 [Frequency
high/low
limit select]
0/1  This parameter sets high
and low limit of run frequency.
0 X
F25
2)
[Frequency
high limit]
0/400
[Hz]
 This parameter sets high
limit of the run frequency.
 It cannot be set above F21
– [Max frequency].
60.0 X
F26 [Frequency
low limit]
0/400
[Hz]
 This parameter sets low
limit of the run frequency.
 It cannot be set above F25 -
[Frequency high limit] and
below F23 – [Start frequency].
0.5 X
F27 [Torque
Boost
select]
0/1
0
Manual torque boost
0 X
1 Auto torque boost
F28 [Torque
boost in
forward
direction]
0/15 [%]  This parameter sets the
amount of torque boost
applied to a motor during
forward run.
 It is set in percent of Max
output voltage.
