Digital Outputs—Alarm/Fault Annunciate (H02-01–03 = 40)
Fault Annunciate
enables you to assign a set of six fault/alarm outputs to Relay Outputs M0-M1, M2-M3, and
M5-M6. M0-M1 is typically assigned to a brake output, but it can be used for fault annunciate. This function will also
trigger the MA-MB-MC fault relay.
You may find it convenient to print the Fault Annunciate Worksheet in this section. By being able to write in the
worksheet’s boxes, you will find it easier to program the feature.
Programming
Fault Annunciate
requires that you determine two 4-digit binary numbers and then convert these to
two 1-digit hexadecimal values. You enter the hexadecimal values when you program the VFD.
To program
Fault Annunciate
(from the
Programming Menu
):
1. Navigate to H02-01 (M0-M1), H02-02 (M2-M3), or H02-03 (M5-M6) and press
until the value blinks.
2. Press the
or
button until H02-xx = 40 appears.
3. Press the
button.
appears.
, select one of three fault output sets (each row is a set).
5. Determine which faults/alarms will trigger the fault output. To enable a fault/alarm, enter 1 in the box;
otherwise, enter 0. Do this for each column in the set.
6. Using the Binary to Hexadecimal Conversion chart (
), determine the 1-digit
hexadecimal value for each 4-digit binary number.
7. Press the
or
and
buttons until the hexadecimal number appears and press Enter.
Example:
Select a Set containing the alarm/fault(s) you want to trigger an output. You can only select from one set. If you
want a relay output based on only LL1 and UL1, you would choose Set 2.
1. Place a “1” below LL1 and UL1 for Set 2.
2. Use table 5-80 to convert the left binary value “1 0 0 0” to Hex 8.
3. Use table 5-80 to convert the right binary value “1 0 1 0” to Hex A.
4. Enter 8A into H02-xx.
Table 5-78: Fault Annunciate Example
First digit = 8
Second digit = A, so
H02-xx = 8A
