C = Continuous capture >> auto re-arm is enabled to collect
new trends until stopped by viewing contents of captured
data.
Cond Defines the condition that will cause the trigger. The possible
options are:
= Equal to + Boolean OR
N= Not Equal to N+ Boolean NOR
> Greater than & Boolean AND
< Less than N& Boolean NAND
Data Defines the trigger value with respect to the read-only
parameter in Trace 1.
Setting up the Trend
The Access level must be Basic or higher level before programming the
drive’s trending feature. To change Access level to Basic, press F10
[Access] key on the main screen. The display will change to ‘Access’
screen. Select Basic by pressing down-arrow key and then press Enter
key. The Access level will change to Basic. Press F10 [EXIT} key again
to exit to the main screen.
Note: The parameter assigned to Trace1 is used for trigger purpose. The
Condition and Data defined in steps 11 and 12 must be satisfied for the
trend to trigger. In most cases the parameter 569 “DrvStatus Flag1”is
assigned to Trace1 for trigger purpose. A value of 18 Hex for Data (Step-
12 below) is used to capture the trend when the drive detects either an
Alarm or a Fault condition. If you are interested in the fault condition only
then set Data as 8 Hex. If you are interested in Alarm condition only then
set Data as 10 Hex.
You can reset the Alarm or Fault in the drive, but don’t Re-Arm the trend
until you print (upload) the trend data into your laptop. Print the Alarm
Queue as well, so that you know which alarm or fault condition was
detected by the drive.
