Programming Steps
1. To program the value of a Program
Group parameter, enter the Program
Group by pressing the ESCape key.
The Program Mode Indicator will
illuminate.
2. Press the Up/Down Arrow keys until
the desired parameter number is
displayed.
3. Press the SELect key. The Program
Mode Indicator flashes, indicating that
you can use the Up/Down Arrow keys
to change the parameter value.
4. Press the arrow keys until the desired
value is shown.
Important: Continuously holding the
Up or Down key will cause the value
to increase or decrease as long as the
key is pressed.
5. When the desired value is displayed,
press the Enter key. This writes the
new value to memory. The Program
Mode Indicator will stop flashing and
the display will flash once indicating
that the new value has been accepted.
Important: If at any time (while in
the Program mode) you wish to abort
the editing process, press the ESCape
key. The original value of the
parameter will remain unchanged and
you will be exited from the Program
mode.
Action Description
Keypad Module Description
Enter
Pressing this key causes the current value
displayed to be entered into memory (only
while in the Program mode). When you press
this key the Program Mode Indicator remains
on, but stops flashing.
Escape
The ESCape key allows you to toggle
between the Display and Program modes.
When the Program mode is active, this key
will disable the editing of a parameter value.
Select
The SELect key enables editing of a
parameter value when the Program mode is
active. When you press this key the Program
Mode Indicator flashes.
Up/Down Arrow Keys
Use the Up/Down Arrow keys to scroll
through a list of parameters, or increase
and decrease parameter values. Press and
hold either key to increase scrolling
speed.
Real time frequency adjustment can be
achieved when using P58 - [Internal
Frequency]. Refer to the User Manual
for further information.
Start
This function is only active when
P46 - [Input Mode] is set to 2. When active,
pressing this key initiates a start command.
Stop
Pressing the Stop key will cause the motor to
stop, using the selected stop mode. Refer to
the P34 - [Stop Mode] parameter.
If the drive has stopped due to a fault,
pressing this key will clear the fault.
Reverse (Change Direction)
This function is only active when
P46 - [Input Mode] is set to 2. When active,
pressing this key causes the motor to ramp
down to 0 Hz and then ramp up to its set
speed in the opposite direction. When the
motor is running, pressing this key causes the
(currently illuminated) LED to flash, indicat-
ing motor rotation while decelerating to zero.
The other LED will illuminate indicating the
commanded direction.
Direction LEDs (Indicators)
The appropriate LED will illuminate continu-
ously to indicate the commanded direction of
rotation. If the second LED is flashing, the
drive has been commanded to change
direction, but is still decelerating.
Important: Actual motor rotation could be
different if motor leads are not connected
properly. See Chapter 4 of the User Manual
for details on verifying correct rotation.
Parameter Number Display
These two digits display the active parameter number for
both Display and Program Group parameters.
Program Mode Indicator
When the Program Mode Indicator flashes, you can edit the
parameter value. When the Display Mode is active, the
indicator will not be lit.
Parameter Value/Fault Number
These four digits display the parameter value or fault code
number.
