The CFW10 Quick Start Guide is a supplement to help get the CFW10 started quickly using the most common installation
and configuration options. This CFW10 Quick Start Guide is not meant to replace the CFW10 User’s Manual. For detailed
instructions, safety precautions, proper mounting, installation, configuration, and operation please refer to the CFW10
User’s Guide. Warning: Only qualified personnel should plan or implement the installation, start-up, operation and
maintenance of this equipment. Personnel must read the entire CFW10 User’s Guide before attempting to install, operate
or troubleshoot the CFW10.

Figure 1 - Power and Grounding Connections

Basic Wiring:

1. Mount the CFW10 to a flat vertical surface.

2. Connect the incoming single phase power leads to the L/L1 and N/L2 connections on the power terminal and
connect the GROUND lead to PE on the power terminal (Refer to Figure 1).

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 power terminal (Refer to Figure 1). Note: Only three-phase AC motors can be used.

4. Apply power to the CFW10 drive. The drive will run self diagnostics and if no problems are found it will display
“rdY”. Note: New CFW10 drives 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.

Keypad Start/Stop (Local Mode): This operation mode is recommended for users who are operating the drive for

the first time without additional control connections.

1. Press the start key. The motor will accelerate from 0.0 to 3.00 Hz (minimum speed P133), in the clockwise
direction. Note: If the direction of rotation is not correct, switch off the drive and wait until the capacitors discharge
completely (as long as 10 minutes) and then swap any two wires at the motor output.

2. Press the key and hold it to increase motor speed (maximum speed P134). Note: On Plus versions use the
keypad potentiometer located on the bottom right of the keypad to adjust speed.

3. Press the stop key. The motor decelerates to 0.0Hz and stops with a display of “rdY”.

The CFW10 does not require parameter programming prior to start up and is ready to operate with the factory default
settings. A parameter example is given below to familiarize the user with parameter navigation, viewing, and
programming.

LED Display

Description

After power is applied to the drive, the display shows
the following message.

Drive is ready to be started.

Press the key to view parameter number. The red
LED on the keypad will light to indicate “parameter
number”.

Press the or arrow keys to select a
parameter.

Select the desired parameter. This
example uses parameter number
P100 (Acceleration Time).

Press the key to view the value of the parameter.
The green LED on the keypad will light to indicate
“parameter value”.

This is the numerical value
associated with the parameter. For
this example then P100=5.0
therefore the acceleration time is set
for 5 seconds.

Press the or arrow keys to change the
parameter value.

Set the new desired value. In this
example the acceleration time has
been increased to 6.1 seconds.
Note: To change parameter values
you must first set the access
parameter P000=5. Some parameter
changes require the drive be
stopped first.

Press the key to store the new value.

The new value for P100
(acceleration time) is stored in

memory.
Repeat this procedure for other parameters that may
need to be changed.

Keypad Start/Stop (Local Mode) continued:

4. If parameters were accessed or changed under Parameter Setup then the last parameter number or value will be
displayed. Scroll up or down with the or keys to the read only parameter P002 (Frequency
Proportional Value for Speed) and press the key to see the value.

5. Return to step 1 and press the start key to start the drive.

Local/Remote Modes:

In the previous section the drive was operated from the keypad
(Local Mode). If you wish to operate in remote mode you will need to
add an external Local/Remote switch. Note: To control speed in
remote mode a speed potentiometer (figure 5) can be added or the
up and down arrow keys on the keypad can be used by setting
P222=0. Plus versions can use the keypad speed potentiometer by
setting P222=3.

Parameters: Confirm DI3 is set to Local/Remote (P265=6).
Control Wiring: Local/Remote switch is N.O (normally open) and is

connected as shown in Figure 3.

2 Wire Start/Stop (Remote Mode):

Parameters:

1. Confirm DI4 is set to START/STOP (P266=4).

2. Set P229=1 (DIx) if you want the 2 wire control in local mode.

3. Confirm P230=1 (DIx) if you want the 2 wire control in remote
mode.

Control Wiring: Verify there is a jumper between XC1-1 (general
enable) and XC1-5 or the drive will not work. Jumper can be
eliminated if DI1 is set to “No Function” (P263=0). Start/Stop switch is
N.O. (normally open) and is connected as shown in Figure 3.

3 Wire Start/Stop (Remote Mode):

Parameters:

1. Set DI1 (Start) to “On” (P263=13). See note below.

2. Set DI2 (Stop) to “Off” (P264=14).

3. Set DI4 to “No function” (P266=0).

4. Set P229=1 (DIx) if you want the 3 wire control in
local mode.

5. Confirm P230=1 (DIx) if you want the 3 wire control
in remote mode.

Control Wiring: “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 DI1 to START (P263=13) an E24
(programming) error will occur until DI2 is set to STOP
(P264=14).

Figure 4 - 3 Wire Start/Stop

Operation from Remote Analog Input (Speed Pot):

Parameters:

1. Confirm P222=1 (Remote Speed Ref=AI1)

Control Wiring: Speed Pot value must be ≥ 5KΩ but ≤ 10KΩ at
2W and is connected as shown in Figure 5.

Figure 5 – Analog Input with Speed Pot

Fault Codes:

When a fault is detected, the drive is disabled and the Fault Code is displayed. (Example E01). To restart the drive after a
fault has occurred, the drive must be reset. Resetting the drive 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 CFW10 User’s Guide.

Parameters Example:

• The following is a typical list of parameter changes that may be needed in addition to the factory default settings

(P204=5).

P000=5 Parameter Access (5 = Password)
P204=5 Loads Factory Default
P100=5 Acceleration Time = 5 seconds
P101=10 Deceleration Time = 10 seconds
P133=3.00 Minimum Frequency = 3.00 Hz
P134=60.00 Maximum Frequency – 60.00 Hz

• Local/Remote parameters allow the drive to be set up to operate from Keypad, Remote Terminal, or a

programmed combination of keypad and terminal inputs.

P221 – Local Speed Reference Selection
P222 – Remote Speed Reference Selection
P229 – Local Command Selection
P230 – Remote Command Selection
P231 – Forward/Reverse Selection

• Read Only Parameters (P002 – P040) can be used for monitoring and troubleshooting. For a full list and

description please read the CFW10 User’s Guide. By monitoring certain read only parameters, drive operational
values can be determined without the use of any other test equipment.

P002 – Frequency Proportional Value (Speed)
P003 – Motor Current
P004 – used to monitor DC Link Voltage.
P005 – Motor Frequency
P007 – Motor Output Voltage
P014 – Last fault

These are just a few examples of drive set-up and parameters. Please read the CFW10 User’s Guide for additional
information.
