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
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.

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.

• 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.

ANALOG INPUT terminal connections ( 3 – 75 HP )
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-05 in Step 5. Only one method may be used as the input source with Fig. 3a Potentiometer
Input being most common.

Changing display to read output speed in percent (%) of full speed.
The display is factory defaulted to show the inverter output frequency in Hz. If desired, the
display can be changed to show the output frequency as a percentage of full speed. To do this
parameter Cn-28 must be changed from (00000) to (00001) as follows:
