9.2 Keypad Navigation
When attempting to control and set various parameters for the inverter it would be useful for the
user to become familiar with keypad navigation and to go through a few function changes before
making the final settings.
9.2.1 Basic Keypad Control (Factory Default, F04=000 & F05=000) Fig. 9.2.1
In its basic form as received from the factory, the inverter output is controlled from the keypad.
Please refer to the F and C parameter list (Sec. 10) to view the factory default settings for the
various parameters. When the inverter is powered up, the display will be flashing and
momentarily show the inverter input voltage. The display will then switch to a minimum output
frequency of 05.0Hz. By pressing the RUN / STOP key the output is active (RUN) and the display
is on solid. Using the UP / DOWN keys, the output frequency may be set in increments of 00.1Hz
from 00.0 to 50.0/60.0Hz. This can be done when the inverter is in the RUN or STOP mode.
When the
RUN / STOP key is toggled to STOP, the set frequency is displayed and the display is again
flashing. The Down key also functions to initiate a RESET after a Fault is cleared.

9.3 Local / Remote Function
In Local mode:
 The RUN command is controlled by the RUN / STOP key.
 Frequency command
-If C41= 000: The UP / DOWN keys control the output
frequency.
-If C41= 001: The front panel potentiometer controls the output
frequency.
In Remote mode:
 The RUN command is controlled via the function set by (F04)
 The frequency command is set by the function set by (F05)
To toggle between Local / Remote press the keys simultaneously.
