Fault text and
code:
Suggested action: Description:
Fault
type:
ChB Dup
Nodeaddr
36020
Soft
The PLC Communications
Adapter Board has detected a
duplicate channel B DH+ node
address.
Check parameter 304 (DIP Switch
ChB) and refer to the table in Chapter
2 to verify the DIP switch settings.
Reset the drive. If the fault persists,
replace the PLC Communications
Adapter Board.
ChA Comm Loss
36021
Soft,
warning,
or none
The PLC Communications
Adapter Board has detected a
loss of channel A
communications with the PLC
controller.
Check for a break in the
communications cable. Verify that all
connections are intact. Clear the fault
by issuing a Clear Fault or a Drive
Reset command, or by recycling
power.
Check parameters 425 (ChA RIO Flt
Sel) and 426 (ChA RIO Warn Sel) to
determine the drive response to faults.
These parameters determine the
resolution of the condition, either fault,
warning, or none. Both parameters are
bit coded.
• Bit 0 determines the resolution to
ChA Res/Pgm/Test. If bit 0 is set in
parameter 425, a soft fault is logged.
If bit 0 is reset in 425 and bit 0 in
parameter 426 is set, a warning fault
is logged. If bit 0 is reset in 425 and
426, no action is taken.
• Bit 1 determines the data output
status of a fault. If set to 0, zeros are
transmitted. If set to 1, the last state
is transmitted.
Check parameter 436 (ChA Flt Sts).
Bit 1=1 indicates a fault if configured
to do so in parameter 425 (ChA RIO
Flt Sel).
Check parameter 437 (ChA Warn Sts).
Bit 1=1 indicates a fault if configured
to do so in parameter 426 (ChA RIO
Warn Sel).
