3-4 LiquiFlo AC Drive, Software Reference Version 6.4
3.3 Drive Control
When the control source is the local keypad/display (the REMOTE LED is off), the
keypad is used to control the drive. This means that the drive will respond to START,
RUN/JOG, and FORWARD/REVERSE commands only from the keypad.
The functions of the keypad keys are described in section 3.5. Refer to the Control
Source parameter description (P.000) in chapter 4 for more information on selecting a
drive control source.
3.4 The Display
The display portion of the keypad/display is a four-character, seven-segment LED. At
drive power-up, SELF is displayed as the drive performs power-up diagnostics. During
drive operation, the display indicates parameter numbers, parameter values, fault or
alarm codes, and drive output values. Figures 3.2 and 3.3 show sample displays.
3.4.1 Display Range
Normally, a minus (-) sign is used as one of the four characters in the display to
indicate a negative value. If a value (including the minus sign) exceeds four
characters, the display will drop the minus sign and display four digits. In this case, the
SPEED LED will flash to indicate that the displayed value is a negative number. Refer
to the examples in table 3.1.
A decimal point to the right of the last digit in the display indicates there is further
resolution (examples A and E) unless a decimal point already appears as part of the
number displayed (example G). In either case, the system uses the full resolution of
the number for drive control, not the displayed value.
