1. DESCRIPTION OF USING 7200GS1.1 Using LCD (or LED) digital
operator

7200GS are standard with LCD digital operator JNEP-34. Moreover,
an LED digitaloperator JNEP-33 is also available. Three two digital
operator have the sameoperation functions except the LCD and
7-segments LED display difference.

The LCD and LED digital operator has 2 modes: DRIVE mode and
PRGM mode.When the inverter is stopped, DRIVE mode or PRGM mode can
be selected bypressing the key PRGMDRIVE . In DRIVE mode, the
operation is enabled. Instead, in thePRGM mode, the parameter
settings for operation can be changed but theoperation is not
enabled.

Note :

Before operation: Control parameter Cn-01 value must be set as
the input ACvoltage value. For example, Cn-01=380 if AC input
voltage is380.

1.5 Control Mode SelectionThe 7200GS standard with four
selectable control modes:

1 GP: V/F control mode (General Purpose V/F control mode).

2 SL: Sensorless Vector Control mode (with motor parameters auto
tuningfunction).

3 PID: PID with Auto Energy Saving Control mode.

4 PG: V/F+PG closed loop Control mode.

The control mode can be selected by parameter Sn-13:

Caution:

1. Factory setting as V/F control mode (GP mode), When the
required controlmode is selected by Sn-13, the selected control
mode is effective only afterturning off the power supply till the
display of digital operator (LCD or LEDdigital operator) is off,
then turn on the power supply again.

2. The AUTO TUNE feature can be used to identify and store the
importantmotor parameters in the first time sensorless vector
operation afterinstallation, and when switching to anyone of the
other three control modes,then switched back to the sensorless
vector control mode, the AUTO TUNEfeature has to be used to
identify and store the motor parameters once again.

The inverter can increase the output torque to compensate the
load increaseautomatically through the auto torque boost function.
Then the output voltage willincrease. As a result, the fault trip
cases can be decreased. The energy efficiency isalso improved. In
the case that the wiring distance between the inverter and themotor
is too long (e.g. more than 100m), the motor torque is a little
short because ofvoltage drop. Increase the value of bn-11 gradually
and make sure the current willnot increase too much. Normally, no

Motor rated slip is set in units of 0.1%

Simplified speed control is performedwithout encoder (PG or
TG).With frequency offset f1 to f2, speedfluctuation due to load is
reduced.

When the output current of the inverter is larger than motor
no-load current (Cn-34),the output frequency of the inverter is
compensated.

The amount of frequency compensation is determined by the
formula below. Themaximum voltage frequency (Cn-04) is 100%.

If the output current is equal to the motor rated current
(Cn-09), the output frequencyis compensated for by the motor rated
slip (bn-08).

If frequency reference is equal to or smaller than minimum
output frequency (Cn-07)or motor is in a regeneration mode, slip
compensation is not performed.

The amount of output frequency compensation in a constant torque
area and aconstant output area is shown in the figure below.

Sn-02 V/f CurveSelectionSn-02=01V/f Curve

V/f pattern Selection 01

V/f pattern is selected by the setting of Sn-02. When V/f
pattern is selected, set inputvoltage of the inverter in Cn-01.

Data 0 — E (of Sn-02): Change disabled

Data F (of Sn-02): Change enabled(V/f patterns are shown on the
following pages).

The V/f pattern is fixed to Sn-02=0F for the SL control mode;
The users have to checkthe V/f pattern to meet the load application
if switched to one of the other threecontrol mode (GP, PID or PG)
from SL control mode.

To select the high starting torque V/f pattern for inverter mode
of capacity 440V100HP (75KW) or more is recommended.

In the sensorless vector control mode (SL), if sufficient torque
cannot be obtained at alow speed, change the V/f pattern setting of
Cn-02 to Cn-08 to high starting V/f.

(3) 4th digit (operation selection when frequency reference is

4th digit = 0: Normal operation (varies with change of
reference)

4th digit = 1: Operation continues with 80% frequency.

When 4th digit = 1 is set, the current master speed frequency
reference iscompared at all times with the one that occurred 0.4
second before. When thecurrent master speed frequency reference
goes below 10% of the one that occurred0.4 second before, operation
continues with 80% (80% frequency) of the masterspeed frequency
reference of the prior one. Consequently, the master speedfrequency
reference of the previous one (0.4 second before) is used as the
currentfrequency reference.

In the following cases, this operation is released and the
inverter returns to normaloperation:

Master speed frequency reference exceeding 80% frequency is
input.

Stop reference is input.

frequency.

(1) 1st digit (selection of stall prevention during
acceleration)1st digit = 0: Stall prevention during acceleration is
enabled.

1st digit = 1: Stall prevention during acceleration is
disabled.

The function of stall prevention during acceleration
automatically extendsacceleration according to load status
(inverter output current), thus preventing themotor from stalling
during acceleration. The stall prevention level duringacceleration
in a constant output area is reduced as follows:

Acceleration stallprevention level of =constant output field
output frequency

When the 1st digit of Sn-10 is 1, the output frequency increases
at the ratedetermined by acceleration time:

(2) 2nd digit (selection of stall prevention during
deceleration)2nd digit = 0: Stall prevention during deceleration is
enabled.

2nd digit = 1: Stall prevention during deceleration is
disabled.

The function of stall prevention during deceleration
automatically extendsdeceleration time according to the magnitude
of the main circuit DC voltage, thuspreventing overvoltage during
deceleration.

When the 2nd digit of Sn-10 is 1, the output frequency decreases
at the ratedetermined by deceleration time. For positioning
applications, specify «stallprevention during deceleration not
provided» (2nd digit = 1) in order to obtainstopping accuracy. With
large inertia loads, use a braking resistor to
preventovervoltage.

(3) 3rd digit (stall prevention during running)3rd digit = 0:
Stall prevention during running is enabled.

Stall prevention operation during running starts decelerating
when the outputcurrent reaches 100ms or greater than the set value
of Cn-30 during frequencycoincidence (operation level of stall
prevention during running). The inverterdecelerates as long as the
output current exceeds the set value of Cn-30(operation level of
stall prevention during running). When the output current goesbelow
the set value, the inverter reaccelerates. The deceleration time
selected inthe 4th digit of Sn-10 is taken. Even during stall
prevention while running, stallprevention during deceleration and
stall prevention during acceleration areenabled.
