Drive status
NvoDrvStatus, nvoStatusWord, nvo-
DigitalInput, nvoAlarmWord, nvoWarning1 and
nvoWarning2 are all 16 bit Boolean values
using the SNVT_state variable type. Individual
bits represent specific drive status states. The
tables provided in Drive Status Bit Definitions
define each bit.
Drive output 1
Network variable nvoOutputPcnt provides an
analog indication of drive operation. In open
loop, this is the drive output frequency in
percentage within the reference range. To
avoid negative numbers, or numbers above
100%, set parameter 204, Min. Reference to
0 Hz, and parameter 205, Max. Reference
equal to parameter 202, Max. Frequency.
In closed loop, this is the drive's feedback
signal within the reference range. For best
operation, set Min. Reference to equal
parameter 413 (414), Min. Feedback, and
Max. Reference to equal parameter 414 (415),
Max. Feedback.
Drive output 2 and Drive Output 3
Output 2 is useful in open loop to report the
drive's output frequency in rad/sec. Output 3
in open loop reports the drive's output in Hz.
Note that in closed loop nvoOutputHz will
report the actual Feedback and not the output
frequency. For best results, set Min. Reference
to 0 Hz and Max. Reference equal to Max.
Frequency. These variable are rarely used in
closed loop.
