•
REV: sets bit #1 (“REV”) and clears bit #0 (“FWD”) in the operation command word (function code
S06).
•
STOP: clears both bit #0 (“FWD”) and bit #1 (“REV”) in the operation command word (function
code S06).
•
RESET: writes a value of “1” to function code S14 (alarm reset command). This will reset a faulted
inverter regardless of the current operation command mode (H30, Y98 etc.) Note that if the inverter
was running (the “FWD” or “REV” buttons were the last buttons pressed on the virtual keypad
before the fault occurred), the STOP button must be clicked prior to clicking the RESET button in
order to clear the FWD and REV bits in the operation command word. The inverter will ignore reset
commands issued through function code S14 as long as a valid run command still exists in the
operation command word.
Note that the inverter will follow the FWD, REV and STOP button commands only when configured
accordingly (refer to section 3.1).
Operation status bits:
These “virtual LEDs” map to the
corresponding bits of the same name in the inverter’s operation
status word (function code M14). When a given bit in the status
word is “1”, then its corresponding indicator will be lit. The indicator
will not be lit if its status word bit is “0”. As an example, the image
in Figure 58 shows FWD (bit #0), NUV (bit #5) and RL (bit #12)
ON, and all other bits OFF.
Hovering the cursor over the virtual LEDs will bring up a tooltip which provides a brief
summary of the indicated function. Refer to Figure 59.
5.9.3 Gauge Window Navigation
Figure 60 shows the two buttons that provide for
navigation of the gauge windows. Gauge windows are
displayed two at a time in the Dashboard Tab, and by
clicking the “right” or “left” buttons, the gauge windows
will scroll in the corresponding direction.
5.9.4 Gauge Window Configuration
Each of the gauge windows can be independently configured to display a user-defined function code
with a variety of flexible configuration options. While the behavior and presentation may vary slightly
depending on the specific gauge chosen, all of the gauges share the following common elements (refer
to Figure 61 for an example):
Gauge Selector:
A drop-down selection box in the upper left-hand corner of the gauge window, which
allows the user to select the type of gauge that will be displayed.
Title:
A text entry box located above the gauge, in which the user can enter a descriptive gauge title
comprised of up to 16 characters.
Units:
A text entry box in which the user can enter an engineering units string comprised of up to 8
characters. This units string will be appended to all locations in the gauge window that display the
designated function code’s current value.
Function Code:
The designated function code whose value is to be reflected on the gauge. Note that
only scanned function codes may be displayed in Dashboard gauges (refer to section 6.2 for a
discussion of scanned function codes).
Multiplier:
The multiplier value is a floating-point number that is used to scale the raw value of a function
code. As its name suggests, the multiplier value is multiplied by the designated function code’s current
raw value in order to calculate the gauge’s indicated value. Negative values can also be used if desired.
Min Value:
The gauge’s minimum indicated value. Negative values can be used if desired (e.g. if a
negative Multiplier attribute is used to generate a negative indicated value). Not all gauges allow
adjustment of the min value.
