Quick Start Guide for Fan Applications
This guide is to simplify the start up of the
MA7200 PLUS Inverter series, 1 to 2 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 with 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 000.0
0
Hz
”. 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.

•
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, 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.

NOTE
The factory default for Sn – 04 and Sn – 05 is set to 0; Digital Operator (Keypad) No
further parameter changes are necessary if this is the desired method of control. If
External Contact set to Sn – 04 or External Analog set to Sn – 05 is desired then proceed
as follows.

•
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.

External Analog
is selected by
Sn-05
in
Step 5
. Only one method may be used as the input source with Fig. 3a Potentiometer
Input being most common.
