SmartWire-DT diagnostics
The variable frequency drive supplies diagnostic messages
for itself and for the DXG-NET-SWD… SmartWire-DT
connection.
Basically, a distinction must be drawn between:
•
Basic diagnostics (basic SmartWire-DT diagnostics)
•
Advanced diagnostics (advanced SmartWire-DT
diagnostics)
•
PROFIdrive parameter channel diagnostics
PROFIdrive parameter channel diagnostics are shown
with fault messages or warnings in the cyclic profile with
PROFIdrive (profile 2).
Basic SWD Diagnostics
A pending diagnostic alarm from the variable frequency drive
will be signaled as a collective diagnostic in the cyclic profile
with input byte 0, bit 4 (DIAG). A device response, if any, will
be described in the advanced diagnostics.
In addition, in all profiles, the following bits
•
ERR (the variable frequency drive stops) or
•
WARN (no reaction of the variable frequency drive)
in the corresponding input bytes are used to show whether
there are any diagnostic alarms (i.e. errors or warnings).
After the cause of the fault is fixed, you can acknowledge a
fault (ERR) as follows:
•
Profile: FaultAck = 1,
•
1-0-A switch in position 0.
Warnings (WARN) cannot be acknowledged, since they are
simply messages without an ensuing response (the variable
frequency drives).
The diagnostic data that corresponds to the PROFIdrive
profile can be sent at any time regardless of the profile
chosen. It is provided via the acyclic services of the relevant
bus system

Advanced SmartWire-DT diagnostics
When there is a collective diagnostic (input byte 0, bit 4
(DIAG)), the variable frequency drive will provide advanced
diagnostic messages.
The following messages are generated by the variable
frequency drive
Table 195. Diagnostic alarms of the PowerXL DG1 variable frequency drive
Value [hex] Meaning Remedy Notes
0x14 No communications between the PowerXL
DG1 communication module and the
PowerXL DG1 Inverter or internal error in the
communication module (Board Fault) If the error continues, switch the supply
voltage off/on
•
Check EMC
•
Replace the variable
frequency drive
0x19 There is a warning from the PowerXL DG1
Inverter Read warning PNU 882.0 and fix the cause Corresponds to the WARN bit in the
corresponding input byte
0x1A There is a PowerXL DG1 Inverter error Read fault PNU 944 to PNU 952
•
Fix the fault and acknowledge the fault message
Corresponds to the ERR bit in the
corresponding input byte
