3.7 OPERATING TIPS
Parameter Access
• When the PROG (or SHIFT-PROG) key is pressed after application of power, 21-MODE will always be the
first parameter displayed.
• If a different parameter is accessed and the Program mode is exited, that parameter will be the point of
entry the next time the programming mode is accessed.
• The WFC HT will remember different “last parameters” for Levels 1, 2, and 3.
• If no key is pressed for 10 minutes while in the programming mode, the WFC HT will automatically revert
back to the operating mode.
Display Scroll Rate
• Three scroll rates are used to speed entry of information into the WFC HT .
• If either the UP or DOWN arrow is pressed and held for five seconds, the rate of change of the display will
increase.
• If the SHIFT key is momentarily pressed while holding one of the arrow keys, the five second delay will be
bypassed.
• If the SHIFT key is pressed a second time while holding an arrow key, the display will scroll at the fastest
rate. This is useful for entering very large numbers as in parameter 84-DISP.
Restoring Factory Settings
• Whenever a parameter’s data is being changed (noted by the Parameter number blinking), the original
factory setting for that parameter can be restored by pressing both the UP and DOWN arrows
simultaneously and pressing the ENTER key.
• To restore ALL parameters to their factory settings, see parameter 81-PRGNO.

3.8 Quick-Start – Running the Motor
This section is for operators who would like to get up and running quickly and with a minimum amount of
research through the manual. Be sure to read sections 3.1 through 3.7 before proceeding. In many cases your
WFC
HT will perform perfectly without making any changes to the factory settings.
A. Perform all procedures for installation as specified in Section 2 – Installation Instructions. REVERIFY
THAT THE PROPER VOLTAGE IS AVAILABLE FOR THE INVERTER BEFORE APPLYING POWER.
FAILURE TO DO THIS CAN RESULT IN EQUIPMENT FAILURE AND PERSONAL INJURY!
B. Apply AC power to the input terminals. For about one second,
all the LED indicators will illuminate and the display will show:
After one second, only the STOP LED will stay on and the
display will change to:
C. The factory settings for the WFC
HT
Series are for keypad only
operation in the forward direction. This means that the REV key and the LOC/REM key are disabled.
Press the FWD key; the display will change to:
D. Press the UP arrow to increase the desired running fre-
quency. When the motor starts to turn, note the direction of
rotation. If the motor is turning in the wrong direction, STOP
THE DRIVE, REMOVE AC POWER AND WAIT FOR THE
BUS CHARGE INDICATOR TO GO OUT. After the Charge indicator is extinguished, reverse any two of
the motor leads at M1, M2 or M3.
E. The length of time that the UP arrow is depressed determines the scroll rate of the display. After it is held
for five seconds, the rate of change will increase. The five second time can be circumvented by
momentarily pressing the SHIFT key while holding the UP (or DOWN) arrow.
F. The inverter is preset to run a “typical” NEMA B induction motor to a maximum speed of 60.00 Hz with
both Acceleration and Deceleration times set to 3.0 seconds. The Jog frequency is set for 5.0 Hz.
G. Use the Arrow keys to set the proper running speed of the motor and the FWD and STOP keys to control
its operation.
