4. escription of Functions
The console set-up functions are explained below. Code numbers 17 and after are selected by selecting code
No. 16 in the basic setting items. At code No. 16, one of the following three modes can be selected.
(1) Special setting items 1 (Sp.set-1) Code numbers 17-97 can be set.
(2) Special setting items 2 (Sp. set-2) Code numbers 17-31 can be set.
(3) Optional setting items (Option) Code numbers 17-24 can be set.
4-1 Basic Setting Items
4-1-1 Reference frequency and its range
The maximum/minimum output frequency, reference frequency, and excess frequency can be set. When the
[START] key is pressed, the motor rotates at the reference frequency.
1) No. 00 Ref (set).F
(reference frequency)
2) No. 05 Top.F
(maximum frequency)
3) No. 11 Min.F
(minimum frequency)
*4) No. 21 OF.Set
(excess frequency)
* protection is performed.
4-1-2 Jog frequency
The jog frequency can be set.
1) No. 01 FOR-JOG.F
(forward jog frequency)
2) No. 02 REV-JOG.F
(reverse jog frequency)
4-1-3 Preset frequency
Operation can be performed at preset 1 and 2 frequencies. Preset 1 or 2 can be selected by the communication
option, multifunction input (input at terminal). In program operation, preset 1 and 2 are used.
1) No. 03 Preset1.F
(preset 1 frequency)
2) No. 04 Preset2.F
(preset 2 frequency)
10
4-1-4 Maximum frequency
The maximum frequency is the upper limit of the reference frequency. Usually, it is the reference frequency
under the condition that the external reference analog frequency is 10V.
1) No. 05 Top.F See the reference frequency timing chart shown in figure 1.
(maximum frequency)
Note: To lower the Top.F setting, data such as Ref(Set).F and PC-Base.F whose upper limit is Top.F must be
lowered in advance. Never forget to lower PC-Base.F (user tend to forget to lower it). However, do not lower
it below the frequency inscribed on the motor rating plate.
4-1-5 V/F function setting
The V/F characteristics can be set based on
the rated output voltage and base fre-
quency of the inverter.
1) No. 06 PC-Base.F
(power control (base)
frequency)
2) No. 07 Rated.Out.V
(rated output voltage)
Note: The rated output voltage can be lowered than the rated motor voltage (Motor.V) and used.
Note 1:For program operation, three more points can be set for the acceleration/deceleration time.
(Four points in total)
Note 2:When the S-shape acceleration/deceleration is used, time from 0 Hz to Top.F and time from
Top.F to 0 Hz increase for the S-shape.
4-1-7 Torque boost quantity setting.
The torque up adjustment can be per-
formed in the low frequency band accord-
ing to the motor load.
1) No. 10 Torq.Boost
(torque boost quantity)
The torque boost quantity
= Output voltage at 0 Hz x 100
Rated output voltage
Note: The setting is invalid when Auto
(auto boost) is selected.
4-1-6 Acceleration/deceleration time (1)
setting.
The arrival time from 0 Hz to the maxi-
mum frequency (Top.F) and the arrival
time from the maximum frequency to 0 Hz
can be set.
1) No. 08 Accl.Time
(acceleration (1) time)
2) No. 09 ecl.Time
(deceleration (1) time)
11
1) No. 11 Min.F
(minimum frequency)
4-1-9 Overload rate setting
The inverter and monitor can be protected
from overload. When the output current of
the inverter exceeds the reference current
determined by the overload rate and the
rated motor current, the overload protec-
tion is performed under the time character-
istics as shown in Figure 7 to stop the
inverter (the 86A relay is turned on).
1) No. 12 OL.Set
(overload rate setting)
Reference current = Rated motor current (A) x Overload rate setting (%)
100
When the operation is performed under the overload condition, the overload counter to count the time required
for overload protection to be performed increases the values and reaches 100% and at this point the overload
protection starts. (When the overload condition is removed, the overload counter decreases the value.)
The overload pre-alarm function can also be used to turn on the multifunction output terminal when the over-
load counter exceeds a specified value. That is, the overload protection can be prevented by detecting the pre-
alarm output to reduce the torque. (See 4-2-21)
4-1-10 V/F pattern selection

tics (Sqr.law) For fan pump load.

2-stage torque setting (See 4-2-4)

tions for the following code numbers 17-97 are set. Even when code No. 16 is already set to Sp.set-1, select
Sp.set-1 again to set those code numbers.
Note 1: External values are limited, and so trip due to limit over does not occur.
Note 2: When No. 18 Lim.F(Lower) is set to a value other than 0.0, the minus side setting in the
reference frequency range is ignored and the plus side setting is used. However, reversal by
using For/Rev is possible.
4-2-2 Output frequency characteristics
1) No. 19 Ex-RefF.set (selection of external frequency setting)
[1] When -10 0 10V is selected, the frequency can be set using voltage.

istics or V/F square law reduction characteristics.
The boost quantity is automatically controlled
based on the motor current and motor internal
constants. See Figure 11 for the auto boost

of the motor torque.
Note 1: The torque limit for the power side is provided by lowering the frequency. To inhibit the
lowering of the frequency, turn off the P side.
Note 2: The torque limit function limits the torque by limiting the acceleration and deceleration and
cannot limit the transient torque. Some difference may be seen compared with the actual torque
depending on the set V/F characteristics and boost.
