Selecting Functions and Editing Parameters
To prepare to run the motor in the powerup test, this section will show how to configure
the necessary parameters:
1. Confirm the TM/PRG DIP switch setting.
2. Select the keypad potentiometer as the source of motor speed command (A001)
3. Select the keypad as the source of the RUN command (A002)
4. Set the inverter’s maximum output frequency to the motor (A003)
5. Set the motor current for proper thermal protection (B012)
6. Set the inverter’s Automatic Voltage Regulation for the motor (A082)
7. Set the number of poles for the motor (H004)
The following series of programming tables are designed for successive use. Each table
uses the previous table’s final state as the starting point. Therefore, start with the first and
continue programming until the last one. If you get lost or concerned that some of the
other parameters settings may be incorrect, refer to “
Restoring Factory Default Settings”
on page 6–8.
TM/PRG DIP Switch Setting - This switch must be in the “PRG” position
(factory default) in order for A001 and A002 settings to be active. Other-
wise, the keypad will be unable to accept a Run command or set the motor
speed with the potentiometer. If the switch setting has been changed, see the
“
DIP Switch Introduction” on page 2–5.
Prepare to Edit Parameters - This sequence begins with powering ON the inverter;
then it shows how to navigate to the “A” Group parameters for subsequent settings. You
can also refer to the “
Keypad Navigational Map” on page 2–25 for orientation through-
out the steps.
Select the Potentiometer for Speed Command -
The inverter output frequency can be set from several
sources, including an analog input, memory setting,
or the network, for example. The powerup test uses
the keypad potentiometer as the speed control source
for your convenience. In the figure to the right, notice
the Potentiometer Enable LED, just above the knob.
If the LED is ON, the potentiometer is already
selected as the source, and you may skip this step.
Note that the default setting depends on the country.
