Quick Start Guide for Fan Applications
This guide is to simplify the start up of the PA7300 Inverter series for fan applications. It is not
intended to replace the PA7300 Installation and Operation Manual 4H358D0250007, and the user is
urged review this manual. There are three methods of control or combinations thereof that that may
be selected; Keypad, Analog Signal (external terminal) or Serial Communication. Only Keypad and
Analog Signal will be covered as Serial Communication is beyond the scope of this manual. For
Serial Communication control or special external control, the user is referred to the PA7300
Installation and Operating Manual.
SAFETY FIRST!
Step 1 - Before Starting the Inverter
• Referring to the PA7300 Instruction Manual, please review and verify that the correct inverter size
for the motor was received free of damage. To ensure personnel safety and to avoid equipment
damage, follow the precautions and the installation procedures for mounting, wiring, and operating
environment.
CAUTION - To avoid damage to the inverter when removing the inverter cover
and/or LCD Operator, refer to Appendix B for the proper procedure.
• In accordance applicable codes make electrical connections to the motor and input power
terminals. (Refer to the block diagram, Fig. 4). No other external connections should be made at
this time, as the initial control will be from the Keypad.
Step 2 - Apply Power to the Drive
• Apply AC power to the Inverter and observe the LCD Display Line 1; it should read
“Freq. Cmd 00.00Hz”. Line 2 should read “TECO”. The red LED on the STOP key should be ON.
The DRIVE and FWD LED’s should be ON. (See Fig. 1 below)
Step 3 - Set Drive to Run Mode
• If the red DRIVE LED is not ON with AC power up, press the PGRM / DRIVE key until the red
Drive LED is ON. The Inverter is now in the RUN mode.

Step 4 - Check Fan Motor Operation
•Enter 10.00Hz for the frequency reference and set parameter Sn-05 = 0010 to disable Reverse
Direction operation. Note: The output from the inverter is displayed in Hz as factory default. If
desired, the output may be displayed in per cent (%) of full speed. (see appendix)
•Press the RUN key, and check the fan direction of rotation. If the direction is not correct, press
the STOP key and wait until the fan has come to a complete STOP. Next, Power Down the
inverter.
Danger
After the power has been turned OFF, wait at least 5 minutes until the charge
indicator extinguishes completely before touching any wiring, circuit boards or
components.
•Reverse any two of the fan motor connections at the inverter ( U(T1),V(T2), or W(T3) ). Next,
following STEP 2, Power-up the inverter; the motor direction should now be correct.
Step 5 – Select Method of Control
•Before selecting the method of control, ensure the inverter is in the STOP mode.
•There are two methods of control or combinations thereof that may be selected; Keypad and
Analog Signal.
RUN / STOP Command - Can be provided from the keypad or from an external contact
(see Fig. 2a).
Speed Reference – Can be from the keypad or from an external analog signal (0 – 10 VDC or
4 – 20 mA). see Fig’s 3a,3b, and 3c.
•The method of control is set by parameter Sn – 04. The table on the next page shows the value
that Sn – 04 needs to be set for the various combinations of control.

•After the method of control has been selected, if external control wiring is required, (e.g. external
analog), Power Down the inverter before removing any covers or making any connections.
In the following pages are wiring examples for Start / Stop, E-Stop, Restart, and Analog
Connections.
Danger
After the power has been turned OFF, wait at least 5 minutes until the charge
indicator extinguishes completely before touching any wiring, circuit boards, or
components.

Fig’s 3a,3b, and 3c.show the various analog input schemes that can be used to control the
output frequency and thus the speed of the fan motor when External Analog is selected by
Sn-04 in STEP 5. Only one method may be used as the input source with Fig. 3a Potentiometer
