Basic Wiring:
1. Mount the CFW09 to a flat vertical surface.
2. For three-phase input power connect the incoming power leads to the R, S, and T connections on the power
terminal and connect the GROUND lead to PE on the chassis (Refer to Figure 1). For single-phase input power
connect the power leads to R and S.
3. Connect the motor leads to the U, V, and W connections on the power terminal and connect the GROUND lead to
PE on the chassis (Refer to Figure 1). Note: Only three-phase AC motors can be used.
4. Apply power to the CFW09 inverter and proceed to “Oriented Start-up”. The inverter will display “P201”on the
LED/LCD displays. This is the first parameter in the “Oriented Start-up”mode. Note: New CFW09 inverters are
shipped with parameters preset to factory defaults. If you need to reload factory defaults at any time, first set
password parameter P000=5 then set factory default parameter P204=5.
Note: When the inverter is powered up for the first time or when the factory default parameter values are loaded
(P204=5), the “Oriented Start-up”sub-routine is run. This sub-routine requests the user to program some basic
parameters to ensure proper operation and motor protection. The motor and inverter nameplate data is required in
order to set these parameters. See page 6 for an example of motor nameplate data required (P400-P406).

Description
After power-up, the display shows the following
message.
Language Selection:
0=Portuguese, 1=English, 2=Spanish,
3=German
Press to enter the programming mode.
Enter the programming mode.
Use and arrow keys to select the
language.
Selected Language:
Select language 1 = English
Press the key to save the
selected option and exit the programming mode.
Exit the programming mode.
Press the arrow key to go to the next
parameter.
Inverter Rated Voltage Selection:
0=220V/230V, 1=380V, 2=400V/415V,
3=440V/460V, 4=480V, 5=500V/525V,
6=550/575V, 7=600V, 8=660V/690V
Continue in this fashion programming the
remaining parameters for the inverter.
Press to enter programming mode,
Press and to select a parameter value.
Press again to store the value.
Press to go to next parameter.
Repeat procedure until the remaining motor
parameters P400, P401, P403, P402, P404, and
P406 required in the “Oriented Start-up”have been
programmed.
When the last parameter P406 has been stored
and the “UP”key pressed, “RDY”is displayed
on the keypad indicating the inverter is ready to
operate.
Note: To repeat the initial power-up procedure:
Set parameter P204=5 (this loads the factory
default parameters) and follow the “Oriented
Start-up”procedure again. Password for
parameter access P000=5
Note: These are the minimum parameters for a perfect adaptation between inverter and motor. With these parameter
settings you can operate the inverter in “Local”mode via the keypad. This operation mode is recommended for users who
are operating the inverter for the first time without additional control connections. For start-up according to this operation
mode, proceed to step 5 on next page.

Keypad Start/Stop (Local Mode):
5. The inverter should still be powered up with a display of “RDY”. Having completed “Oriented Start-up”, keypad
navigation should now be familiar. Verify parameter P202=0 (Type of Control = V/F 60Hz). This is the factory
default value and should already be set to 0. Note: To change the value of P202 and all other parameters, P000
must first be set to 5 (Password Parameter P000=5).
6. Scroll down to the read only parameter P002 (Motor Speed) and press to see the speed value.
7. Press the start key. The motor will accelerate from 0 to 90 RPM (minimum speed), in the clockwise
direction. Note: If the direction of rotation is not correct, switch off the inverter and wait until the capacitors
discharge completely (as long as 10 minutes) and then swap any two wires at the motor output.
8. Press the key and hold it to increase motor speed.
9. Press the FWD / REV key to change directions. The green and red LEDs on the left side of the keypad
indicate rotation direction (Fig. 2)
10. Press the stop key. The motor decelerates to 0 RPM.
11. Press the key and hold it. The motor accelerates from 0 RPM to the JOG speed set at P122. Release the
key and the motor decelerates down to 0 RPM.
Notes: (1) The “Acceleration Time”and “Deceleration Time”is set at P100 and P101 respectively (Default value is
20sec). If the acceleration current becomes too high, especially at low frequencies (<15Hz), an inverter over-current
(E00 or E05) may occur requiring the Torque Boost at P136 to be decreased. Increase/decrease the content of P136
gradually until an operation with constant current over the entire frequency range is obtained. Refer to P136 in
Chapter 6 of the CFW09 User’s Guide for a full explanation.
(2) If E01 fault occurs during deceleration, increase the deceleration time at P101.
(3) Minimum and Maximum speeds are set at P133 and P134 respectively.
(4) For a complete description of Parameters and Error codes refer to Chapters 6 and 7 in the CFW09 User’s Guide.
Local/Remote Modes (Hand-Off-Auto):
In the previous section the inverter was operated from the keypad (Local Mode).
Note the green local indicator LED on the bottom right of the keypad (Fig.2). For
the factory default programming, the selection of the operation mode
(Local/Remote) is made via the “Local/Remote”key (default is Local). To pass
default of the key to remote, set P220=3. With this setting the inverter will power
up in remote mode. Note the red remote indicator LED on the bottom right of
keypad (Fig. 2). If you wish to use an external Local/Remote switch (Hand-Off-
Auto) set P220=4, connect the switch to one of the Digital Inputs (DI2-DI6), and
set the corresponding parameter (P264 to 268=1). To always run in Local mode
set P220=0. To always run in Remote mode set P220=1.
2 Wire Start/Stop (Remote Mode):
Parameters:
1. Set DI1 to START/STOP (P263=1).
2. Set P224=1 (DIx) if you want the 2 wire control in local mode.
3. Set P227=1 (DIx) if you want the 2 wire control in remote mode.
Control Wiring: Verify there is a jumper between XC1-8 and XC1-10 or the
inverter will not work. Start/Stop switch is N.O. (normally open) and is
connected as shown in Figure 3.
Figure 3 –2 Wire Start/Stop

3 Wire Start/Stop (Remote Mode):
Parameters:
1. Set DI1 to GENERAL ENABLE (P263=2).
2. Set DI3 to START (P265=14). See note below.
3. Set DI4 to STOP (P266=14).
4. Set P224=1 (DIx) if you want the 3 wire control
in local mode.
5. Set P227=1 (DIx) if you want the 3 wire control
in remote mode.
Control Wiring: Verify there is a jumper between XC1-8
and XC1-10 or inverter will not work. “Start”and “Stop”
are momentary push button switches and are connected
as shown in Figure 4. “Start”is a N.O. (normally open)
contact and “Stop”is a N.C. (normally closed) contact.
Note: When initially setting DI3 to START (P265=14) an
E24 (programming) error will occur and the display will
flash until DI4 is set to STOP (P266=14).
Figure 4 - 3 Wire Start/Stop
Operation from Remote Analog Input (Speed Pot):
Parameters:
1. P222=1 (Remote Speed Ref=AI1)
2. P235=0 (Analog Input Signal =0-10Vdc)
Control Wiring: Connect jumper between XC1-13 and XC1-14 or Speed
Pot will not work. Speed Pot value must be ≥5KΩbut ≤10KΩat 2W and
is connected as shown in Figure 5.
Dip Switch Settings: Analog Input 1 (AI1) is set at 0-10Vdc (default) by
the S1-2 Dip Switch on the control board (S1-2=OFF). To detect 4-20mA,
set S1-2=ON and set P235=1. Note: S1-1 is for Analog Input 2. See the
CFW09 User’s Guide for full explanation of analog inputs.
Figure 5 –Analog Input with Speed Pot
Fault Codes:
When a fault is detected, the inverter is disabled and the Fault Code is displayed. (Example E01). To restart the inverter
after a fault has occurred, the inverter must be reset. Resetting the inverter can be done by disconnecting and reapplying
AC power (power-on reset), by pressing the “O/RESET”key (manual reset), automatic reset, or via digital inputs. For
details on Reset and a full list and description of Fault Codes please read Chapter 7 in the CFW09 User’s Guide.
