Introduction
This Start-Up Guide is not meant to replace the compete Instruction Manual. This is a
supplementary document intended to provide concise instructions covering the most common
installation and configuration options. For detailed instructions, safety precautions, proper
mounting, installation, configuration and operation, please refer to the appropriate revision of
the Axpert-VT240S complete Instruction Manual.
WARNING: Only qualified personnel should plan or implement the installation, start-up,
operation and maintenance of this equipment. Personnel must read the entire INSTRUCTION
MANUAL before attempting to install, operate or troubleshoot the Axpert-VT240S.
There are ten key elements to the basic installation and start up of a Variable Frequency Drive. In this
Start-Up Guide we will cover the following steps. For more information, please refer to the complete
Instruction Manual.
1. Physically install the VFD with consideration for ambient temperature and proper cooling, adequate
room around the VFD for airflow and mounting properly to protect the VFD for the specific environment.
If mounted inside or outside of another enclosure, make sure the environment that the VFD is mounted
in is properly evaluated and the correct NEMA rated drive or enclosure is used to suit the application.
For example, if outside, a NEMA3R, clean room, NEMA1 or IP20, a dirty, dusty environment, a
NEMA12.
2. Check that the VFD is of the correct voltage and current rating to suit the application.
3. Use the required peripheral devices, such as Circuit Breaker or Input Fuses, Line or Load reactors,
DC Bus choke, DB resistors, push buttons and selector switches to suit the application.
4. Connect the AC input voltage, AC motor and control wiring using proper sized cables and wires with
appropriate grounding and shielding to assure proper operation. Make sure that the requirements of
the local electrical codes are adhered to for a proper installation.
5. Power up the VFD and familiarize yourself with the operation of the keypad, such as navigating
through the parameters and how to change parameters.
IMPORTANT NOTE! Whenever undertaking the start-up of a VFD, especially if anyone has been
operating the VFD prior to the start-up, it is advisable to set all of the parameter values to their
factory default values. By knowing that all of the parameters are at the default values, this can
save a lot of troubleshooting later on through mis-operation by having a parameter set to a
value not needed by the application. An incorrectly programmed parameter can look like a
defective VFD. Setting parameter C09-7 to “9” will reset all user parameters to default. If drive is
supplied with some logic, ensure that you have related parameter list to input after default.
6. Review the parameters and determine which ones need to be changed to meet the requirements of
your application. The motor parameters (B00-0 to B00-7 for v/f control and B01-0 to B01-7 for vector
control mode) must be entered for precise protection of the AC motor used. The method for start/stop,
speed reference, and values for the Accel/decel rate and minimum and maximum speeds are all
important parameters to be considered.
7. Start the motor and assure proper rotation and the expected load currents are displayed, (See
Parameter D02-0 - Output Current in Amps). Find the read-only parameters that display information
like a digital meter to show operational parameters such as input and output voltages, DC Bus voltage,
load currents, motor speed and frequency, power used and run time.
8. Review the Fault Codes and what they mean. Look at the Fault History parameters and how the
VFD will display the last ten faults and operational values that existed at the time of the fault.
9. Test all of the system operators, such as pushbuttons, remote keypad, selector switches, to assure
proper operation and control. Verify starting and stopping and correct speed control.
10. Once the installation is complete and the system operates as desired, It is advised to fully
document all parameter value changes, jumper changes and control wiring to simplify troubleshooting
or system duplication in the future. This will help to get better technical support if need arises.

Chapter-1: Installation Procedure
Always confirm the following points before turning ON the power after completing wire.
1. First, visually inspect the VFD
and ensure that the VFD has not been damaged in transport. If any
damage has occurred, do not energize the VFD, and contact the supplier.
2. Mount the VFD according to the detail Instruction Manual, Chapter 2 “Installation and Wiring”.
3. Be aware of the ambient temperature. Use the VFD within the specified ambient temperature
(50ºC).
4. Connect the main circuit terminals L1, L2, L3 to the line side and terminals U, V, W to the motor side
as shown in Fig.1. Refer Chapter-2 of detail Instruction Manual for the terminal layout of other models.
Tighten the terminals with the specified torque as specified in Table-2-3, Chapter-2 of detail Instruction
manual for the Axpert-VT240S Series AC Drive. Make sure that none of the terminal section screws
are loose and there is no short circuit state in the terminals caused by wire scraps, etc.

5. Connect the system ground to the ground terminal of the VFD.
6. Remove the coupling to the motor and machine, so that the machine can be run as a single unit.
7. With the 400V Series (075H or higher), there are some sections in the inverter, which operate with
an AC power supply, such as fan and magnetic contactor. In this case, set the power changeover
connector on the transformer auxiliary PCB according to the power voltage. If this connector is not
set correctly, the fan and magnetic contactor could burn.

Automatic tuning measures the constants of the connected motor, and automatically adjusts the
parameters so that the system is used to the fullest.
The VT240S automatic tuning function performs different measurements for each of the four control
modes. Carry out automatic tuning each time the motor being used or the applicable control mode is
changed. The automatic tuning mode is set with parameter B19-0 (automatic tuning selection). Refer

4-2 Speed reference setting selection
The ten types of speed setting inputs shown below can be used.
One of the ten types of inputs can be selected by setting a parameter or with the sequence input.
In default condition, the speed reference is from the digital operation panel (keypad) A00-0. The speed
reference can be assigned to any of the following.
4-2-1 Keypad (A00-0)
The frequency reference from keypad when the start/stop operation is through terminal can be assigned
by setting following parameters.
Step-1: Set C03-D=0.
Step-2: Set the desired frequency in A00-0.
4-2-2 Potentiometer (or 0-10V)
To assign the potentiometer (or 0-10V) as speed reference, one needs to connect the potentiometer (or
0-10V) to any one analog input from AI1, AI2 or AI3. Follow below steps to use potentiometer (or 0-10V)
as speed reference.
Step-1: Select the analog input. In this example, the potentiometer (or 0-10V) is connected to AI1. Set
C12-0=1 and DIP switch DS1-2 to OFF position.
2k/2W
AI1

Potentiometer
COM
DS1-2=OFF
Step-2: Assign the selected analog input (AI1, AI2 or AI3) to speed setting input1, speed setting input2 or
speed setting input3 using C07-0, C07-1 and C07-2. By default, AI1 is assigned to speed setting input1
(C07-0=2)
Step-3: Set speed setting input using C03-D, C03-E or C03-F. In our example, as we have used speed
setting1, we need to set C03-D=16: ON Fixed.
If one requires switching the speed reference between digital operation panel (A00-0) and potentiometer
(or 0-10V), assign any sequence input (PSI) to C03-D. For example, PSI5 is assigned to switch reference.
Set C03-D=5 and C03-3=0. When PSI5 is open, the speed reference will be through keypad (A00-0) and
when PSI5 is closed the speed reference will be potentiometer (or 0-10V).

4-2-3 Speed reference through 4-20mA
To assign the 4-20mA as speed reference, one needs to connect the 4-20mA analog signal to any one
analog input from AI1, AI2 or AI3. Follow below steps to use 4-20mA as speed reference.
Step-1: Select the analog input. In this example, the 4-20mA analog signal is connected to AI2. Set
C12-4=2 and DIP switch DS1-3 to ON position.
Step-2: Assign the selected analog input (AI1, AI2 or AI3) to speed setting input1, speed setting input2 or
speed setting input3 using C07-0, C07-1 and C07-2. By default, AI2 is assigned to speed setting input2

Step-3: Set speed setting input using C03-D, C03-E or C03-F. In our example, as we have used speed
setting2, we need to set C03-E=16: ON Fixed.
If one requires switching the speed reference between digital operation panel (A00-0) and 4-20mA),
assign any sequence input (PSI) to C03-E. For example, PSI5 is assigned to switch reference. Set
C03-E=5 and C03-3=0. When PSI5 is open, the speed reference will be through keypad (A00-0) and
when PSI5 is closed the speed reference will be 4-20mA.
4-2-4 Speed reference through ±10V signal
To assign the ±10V signal as speed reference, one needs to connect the ±10V analog signal to any one
analog input from AI1, AI2 or AI3. Follow below steps to use ±10V signal as speed reference.
+/-10V signal
AI
3
COM
Step-1: Select the analog input. In this example, the ±10V analog signal is connected to AI3.
Step-2: Assign the selected analog input (AI1, AI2 or AI3) to speed setting input1, speed setting input2 or
speed setting input3 using C07-0, C07-1 and C07-2. Assign AI3 to speed setting input3 (C07-2=4)
Step-3: Set speed setting input using C03-D, C03-E or C03-F. In our example, as we have used speed
setting3, we need to set C03-F=16: ON Fixed.
If one requires switching the speed reference between digital operation panel (A00-0) and ±10V signal),
assign any sequence input (PSI) to C03-F. For example, PSI5 is assigned to switch reference. Set
C03-F=5 and C03-3=0. When PSI5 is open, the speed reference will be through keypad (A00-0) and
when PSI5 is closed the speed reference will be ±10V signal.
4-2-5 Speed reference through Increment / Decrement push buttons (static pot or electronic pot)
To assign the Increment / Decrement push buttons as speed reference, one needs to connect two push
buttons to PSI for increment and decrement the speed reference. Follow below steps to use static pot as
speed reference.
Step-1: Assign FUP and FDW to any PSI using C04-7 and C04-8 respectively. In this example, PSI5 is
assigned to Increment push button and PSI6 is assigned to Decrement push button. Set C04-7=5,
C04-8=6, C03-3=0 and C03-4=0.

PSI5
Step-2: Set C03-D=0.
Note that the speed reference will be incremented or decremented from the A00-0 set value. So, set the
initial desired speed reference to A00-0. When the ON state continues, the frequency is incremented/
decremented with the currently valid acceleration time.
4-2-6 Use of Multiple Preset Speed reference
To assign multiple preset speed reference, one needs to connect selector switches to digital inputs (PSI)
to select the desired preset speed. Follow below steps to use preset speed reference. This drive has
facility to select the speed as per the binary logic as well as direct method. Both the methods are
described here. In this example, only two digital inputs PSI2 and PSI3 are used for preset speed setting.
PSI1 is used for start.
Binary method for speed selection:
Step-1: Connect selector switch for start between PSI1 & RY0.
Step-2: Assign PSI2 to S0 by setting C04-2=2 and PSI3 to S1 by setting C04-3=3. As PSI1 and PSI2
are assigned to other functions in default conditions, clear them first by setting C03-1=0 and C03-7=0.
Connect selector switches S0 and S1 between PSI2 & RY0 and PSI3 & RY0 respectively.

Step-3: Set C04-0=16
Step-4: Set B11-8=1 for binary method for speed selection
Step-5: Set the desired frequency in parameter B11-0, B11-1 and B11-2
Step-6: When both the switches are OFF, the previous set frequency will be selected.
Step-7: Keep only S0 switch to ON position, the frequency set in B11-0 will be selected.
Step-8: Keep only S1 switch to ON position, the frequency set in B11-1 will be selected.
Step-9: When both the switches are kept to ON position, the frequency set in B11-2 will be selected.
Below table shows how the multiple preset speed (frequency) can be selected using more digital inputs
(PSI1 ~ PSI7). Refer detail instruction manual for more detail and timing diagrams on this
application.
