Phenomenon/Symptom
Probable Causes
1
None of the LEDs on the interface
card would light.
•
The inverter is not powered ON.
•
The card is not properly installed.
•
The card is faulty.
2
er4
alarm cannot be reset.
(The POWER LED lights in red.)
•
The card is not properly installed.
•
The card is faulty.
3
er5
alarm cannot be reset.
(The POWER LED flashes in red.)
•
Cabling is not properly done.
•
The target input NV has not received data within the time specified by
the receive heartbeat.
4
No commissioning possible.
•
An XIF file designed for different products is used or the XIF file version
is not latest.
•
Cabling is not properly done.
•
The card is not grounded. (Communication impossible due to noise)
5
Data entered to NVs or CPs after
commissioning cannot be
validated on the inverter.
•
After commissioning of the card, the inverter is not restarted or reset
with a LONWORKS integration tool (e.g., LonMaker).
•
The network is offline or disabled.
6
Output NV cannot be monitored.
•
The SCPT_maxSendTime value specified is not greater than the
SCPT_minSendTime value specified.
•
The SCPT_minDeltaLevel value specified is too large so that the
change cannot be recognized.
•
The card is in the waiting time specified by
UCPT_SendDelayAfterDevRdy.
•
The network is offline or disabled.
7
A run or frequency command
cannot be validated on the
inverter.
•
y98 or UCPT_LinkFunc is not set to "3."
•
Any higher priority run or frequency command is enabled by inverter's
function codes (y99,
LE
or
LOC
terminal command).
•
After commissioning of the card, the inverter is not restarted or reset
with a LONWORKS integration tool (e.g., LonMaker).
•
The network is offline or disabled.
8
Turning nviXcmd_1 to 5 or
nviFWDcmd command ON is not
validated on the inverter.
•
y98 or UCPT_LinkFunc is not set to "2" or "3."
•
Terminals [X1] to [X5] and [FWD] are assigned commands not
accessible via the LONWORKS network.
9
Turning nviDOcmd_Y1 or Y2 ON
or entering data to nviAOcmd
cannot output it to the inverter
terminal.
•
Universal DO and Universal AO are not assigned to terminals [Y1],
[FMI] and [FM2] or [FMA] and [FMP], respectively.
10
The LONWORKS network cable is
not connected to the card, but the
COMM LED lights.
Normal operation. No problem.
11
The speed command is validated
on the inverter, but the actual
motor speed is different from the
commanded frequency.
Refer to the user's manual of an inverter, "Motor is running abnormally."
