Quick Start Guide for Fan Applications

This guide is to simplify the start up of the MA7200 PLUS Inverter series, 3 to 75 HP, for fan applications. It is not intended to replace the MA7200 PLUS Installation and Operation Manual, 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 control 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 MA7200 PLUS Installation and Operating Manual.

SAFETY FIRST!

Step 1 - Before Starting the Inverter

• Referring to the MA7200 PLUS Instruction Manual, please review and verify that the correct inverter size for the associated 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 000.00Hz”. 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 4 - Check Fan Motor Operation

• Enter 10.00Hz for the frequency reference and set parameter Sn-08 = 1 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

• 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.

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.

Step 5 – Select Method of Control

• Before selecting the method of control, verify that 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 RUN/STOP method of control is set by parameter Sn – 04 and the Speed Reference is set

by parameter Sn – 05. The following table shows the values to be set when selecting.

Speed Reference

Sn – 05=

* NOTE

The factory default for both Sn – 04 and Sn – 05 are set to =0; Digital Operator (Keypad).

No further parameter changes are necessary if this is the desired method of control. If either External Contact set by Sn – 04 or External Analog set by Sn – 05 are desired (or both) then proceed as follows.
