“F” Group: Main Profile Parameters
The basic frequency (speed) profile is 
defined by parameters  contained in the 
“F” Group as shown to the right. The 
output frequency is se t in Hz, but accel-
eration and deceleration are specified 
seconds (the time to ramp from zero to 
maximum frequency, or from maximum 
frequency to zero). The motor direction 
parameter determines whether the 
keypad Run key produces a FW or RV 
command. This parameter does not 
affect the [FW] terminal or [RV] intelligent te rminal function, which you configure separately.
Acceleration 1 and Decele ration 1 are the standard default accel and decel values for the main 
profile. Accel and decel values  for an alternative profile are specified by using parameters Ax92 
through Ax93. The motor direction selection (F004)  determines the direction of rotation as 
commanded only from the keypad. This setting applie s to any motor profile (1st, 2nd, or 3rd) in 
use at a particular time.

“A” Group: Standard Functions
Basic Parameter 
SettingsThese settings affect the most fundamental behavi or of the inverter—the outputs to the motor. 
The frequency of the inverter’s AC output determines the motor speed. You may select from 
three different sources for the reference speed.  During application development you may prefer 
using the potentiometer, but you may switch to an  external source (control terminal setting) in 
the finished applic ation, for example.
The base frequency and maximum frequency settin gs interact according to the graph below 
(left). The inverter output operati on follows the constant V/f curve  until it reaches the full-scale 
output voltage. This initial straight line is th e constant-torque part of the operating characteris-
tic. The horizontal line over to the maximum freque ncy serves to let the motor run faster, but at 
a reduced torque. This is the constant-horsepowe r part of the characteristic. If you want the 
motor to output constant torque over its entire operating range (limited to the motor nameplate 
voltage and frequency rating), then set the ba se frequency and maximum frequency equal as 
shown (below right).
NOTE: The “2nd motor” and “3rd motor” settings in  the tables in this chapter store an alter-
nate set of parameters for additional motors. Th e inverter can use the 1st, 2nd, or 3rd set of 
parameters to generate the output frequency to the motor. See  “
Configuring the Inverter for 
Multiple Motors” on page 4–76.

NOTE: Intelligent terminals [OPE] (option code 31)  or [F-TM] (option code 51) can override 
settings A001 and A002 when ei ther terminal is ON and the operation commands for that 
terminal is enabled.
NOTE: When using a remote operator (SRW) to ope rate the inverter, the REMT (remote) key 
allows you to enter the frequency setting and operation commands remotely.
NOTE: When the DeviceNet option board (SJ-DN) is installed, you may keep the A002 
default setting because the Run Command Source is automatically set via DeviceNet. Other-
wise, only use settings A002 = 01, 02, or 03.
NOTE: The base frequency must be less than or e qual to the maximum frequency (ensure that 
A003 ≤ A004).
 
Analog Input and 
Miscellaneous 
SettingsThe inverter has the capability  to accept external analog inputs  that can command the output 
frequency to the motor. Signals including voltage input (0 to +10V) at terminal [O], bipolar 
input (-10 to +10V) at terminal  [O2], and current input (4 to 20mA) at terminal [OI] are avail-
able. Terminal [L] serves as signal ground for th e three analog inputs. The analog input settings 
adjust the curve characteristics between the analog input and the frequency output.
Adjusting [O–L]  characteristics – In the 
graph to the right, A013 and A014 select 
the active portion of the input voltage 
range. Parameters A0 11 and A012 select 
the start and end frequency of the 
converted output frequency range, respec-
tively. Together, these four parameters 
define the major line  segment as shown. 
When the line does not begin at the origin 
(A011 and A013 > 0), then A015 defines 
whether the inverter outputs 0Hz or the 
A011-specified frequency when the 
analog input value is less than the A013 
setting. When the input voltage is greater 
than the A014 ending value, the inverter 
outputs the ending frequency specified by 
A012.

Multi-speed and 
Jog Frequency 
SettingsThe SJ7002 inverter has the capability to store and  output up to 16 preset frequencies to the 
motor (A020 to A035). As in traditional motion terminology, we call this  multi-speed profile 
capability. These preset frequencies are selected by means of digital inputs to the inverter. The 
inverter applies the current ac celeration or deceleration settin g to change from the current 
output frequency to the new one. The first mult i-speed setting is duplicated for the second 
motor settings (the remaining 15 multi-speeds apply only to the first motor).
The jog speed setting is used whenever the Jog  command is active. The jog speed setting range 
is arbitrarily limited to 10 Hz to provide safety  during manual operation. The acceleration to the 
jog frequency is instantaneous, but you can ch oose from six modes for the best method for 
stopping the jog operation.

Torque Control 
AlgorithmsThe inverter generates the motor output 
according to the V/f algorithm or the 
sensorless vector control algorithm. Param-
eter A044 selects the inverter torque control 
algorithm for generating the frequency 
output, as shown in the diagram to the right 
(A244 and A344 for 2nd and 3rd motors, 
respectively). The factory default is 00 
(constant torque V/f control).
Review the following descriptions to help 
you choose the best torque control 
algorithm for your application.
 The built-in V/f curves are oriented toward developing constant torque or 
variable torque characteristics (see 
graphs below).
 The free-setting curve provides an even  more flexible characteristic, but it 
requires more parameter settings.
 Sensorless vector control calculates an  ideal torque vector based on current 
motor position, winding currents, and so 
on. It is a more robust control method than the V/f control methods. However, it is more 
dependent on actual motor paramete rs and will require you to set these values carefully or to 
perform the auto-tuning procedure (see  “
Auto-tuning of Motor Constants” on page 4–71) to 
obtain optimum performance.
 Sensorless vector control, 0Hz domain increases the low-speed torque performance (0– 2.5Hz) via an advanced Hitachi torque control algorithm. However, you will need to size the 
inverter for one frame size larger than the motor for proper operation.
 Vector control with sensor requires expansio n card SJ–FB encoder feedback board and a 
motor shaft encoder. Choose this method when  precise position/velocity control is required.

Constant and Variable Torque –  The graph below (left) shows the constant torque character-
istic from 0Hz to the base frequency A003. The vo ltage remains constant for output frequencies 
higher than the base frequency.
The graph above (right) shows the general characte ristic for variable torque. The curve may be 
best described in thre e sections, as follows:
a. The range from 0Hz to 10% of the base freque ncy is the constant torque characteristic. 
For example, a base frequency of 60Hz ends  the constant torque characteristic segment 
at 6Hz.
b. The range from 10% of the base frequency  to the base frequency is the variable 
(reduced) torque characteristic. The voltage is  output in the curve of frequency to the 1.7 
power.
c. After reaching the base frequency, the characteristic maintains a constant output voltage 
for higher frequencies.
Using parameter A045 you can modify the voltage  gain of the inverter. This is specified as a 
percentage of the full-scale setting AVR (Automatic Voltage Regulation) in parameter A082. 
The gain can be set from 20% to 100%. It must  be adjusted in accordance with the motor 
specifications.
Torque Boost – The Constant and 
Variable Torque algorithms feature an 
adjustable  torque boost  curve. When the 
motor load has a lot of inertia or starting 
friction, you may need to increase the 
low frequency starting torque character-
istics by boosting the voltage above the 
normal V/f ratio (shown at right). The 
boost is applied from zero to 1/2 the 
base frequency. You set the breakpoint 
of the boost (point A on the graph) by 
using parameters A042 and A043. The 
manual boost is calculated as an 
addition to the standard straight V/f line (constant torque curve).
Be aware that running the motor at a low speed for a long time can cause motor overheating. 
This is particularly true when ma nual torque boost is ON or if the motor relies on a built-in fan 
for cooling.
NOTE: Manual torque boost applies only to consta nt torque (A044=00) and variable torque 
(A044=01) V/f control.
NOTE: The motor stabilization parame ter H006 is effective for constant torque (A044=00) and 
variable torque (A044=01) V/f control.

V/f Free-setting –  The free-setting V/f inverter mode of  operation uses voltage and frequency 
parameter pairs to define seven points on a V/ f graph. This provides a way to define a multi-
segment V/f curve that be st suits your application.
The frequency settings do require that 
F1  ≤ F2  ≤ F3  ≤ F4  ≤ F5  ≤ F6  ≤ F7; their 
values must have this ascending order 
relationship. However, the voltages V1 
to V7 may either increase or decrease 
from one to the next. The example to the 
right shows the definition of a complex 
curve by following the setting require-
ments.
Free-setting f7 (B112) becomes the 
maximum frequency of the inverter. 
Therefore, we recommend setting f7 
first, since the initial value of all default 
frequencies f1–f7 is 0Hz.
NOTE: The using of V/f free-setting operation specifies parameters that override (make 
invalid) certain other paramete rs. The parameters that become  invalid are torque boost (A041/
A241), base frequency (A003/A203/A303), a nd maximum frequency (A004/A204/A304). In 
this case, we recommend leaving their settings at the factory default values.
The V/f free-setti ng endpoint f7/V7 
parameters must stay within the more 
basic inverter limits in order for the 
specified free-setting characteristic 
curve to be achieved. For example, the 
inverter cannot output a higher voltage 
than the input voltage or the AVR 
setting voltage (Automatic Voltage 
Regulation), set by  parameter A082. 
The graph to the right shows how the 
inverter input voltage would clip (limit) 
the characteristic curve if exceeded.
Sensorless Vector Control and , Sensorless Vector Control, 0Hz Domain –  These advanced 
torque control algorithms improve the torque performance at very low speeds:
 Sensorless Vector Control – improved torque  control at output frequencies down to 0.5 Hz
 Sensorless Vector Control, 0Hz Domain – im proved torque control at output frequencies 
from 0 to 2.5 Hz.
These low-speed torque control algorithms must  be tuned to match the characteristics of the 
particular motor connected to your inverter. Si mply using the default motor parameters in the 
inverter will not work satisfactorily for th ese control methods. Chapter 4 discusses motor/
inverter size selection and how to set the moto r parameters either manually or by using the 
built-in auto-tuning. Before using the sensor less vector control methods, please refer to 
“
Setting Motor Constants for Vector Control” on page 4–69.
NOTE: When the inverter is in SLV (sensorless vector) mode, use B083 to set the carrier 
frequency greater than 2.1 kHz for proper operation.
NOTE: You must disable sensorless vector operatio n when two or more motors are connected 
(parallel operation) to the inverter.

Vector Control with Encoder Feedback –  This method of torque control uses an encoder as a 
motor shaft position sensor. Accurate position feed back allows the inverter to close the velocity 
loop and provide very accurate speed control, even with variations in motor loads. To use 
encoder feedback you will need to add an SJ –FB Encoder Feedback Card in the inverter’s
