Troubleshooting Using PROFIBUS Diagnostics
Table 81 Extended diagnostic information (continued)
Diagnostic Status
Mapped output register
rejected
Mapped input register
rejected
Node storage failed
Invalid option parame-
ters
Commissioning mode
is active
Possible Cause(s)
One of the output configuration parameters
P160 - P169 has been rejected by the Inverter.
One of the input configuration parameters
P170 - P179 specifying a Modbus register that
does not exist.
Your Inverter version has not been properly
verified with this version of the 3G3AX-MX2-
PRT-E.
Your Inverter version has not been properly
verified with this version of the 3G3AX-MX2-
PRT-E.
Commissioning mode is NOT an error, but it
can influence normal system operation. During
commissioning mode, Inverter parameter
access takes priority over cyclic data
exchange. Accessing Inverter parameters will
therefore delay cyclic data exchange causing
unexpected latencies.
Corrective Action
Check (and correct) the following items:
• Is one of the parameters P160 - P169
specifying a Modbus register that does not
exist?
• Is a Modbus register specified twice in the
output parameter registers P160 - P169?
• If one of the parameters P160 - P169 is
specifying a double-word Modbus register:
Are both the high- and low-wordss speci-
fied in sequence by two consecutive
parameters?
• Is one of the output parameters P160 -
P169 specifying a Modbus register that is
read only? (A register is read-only if it has
an 'R' in the 'R/W' column in section B-4-2
@
of the MX2-A
Inverter user's manual.)
• Is one of the output parameters P160 -
P169 specifying a Modbus register of
which the parameter is not run-mode edit-
able? (Refer to section 3-2-3 of the
@
MX2-A
Inverter user's manual.)

If you are not busy configuring the Option
Board or drive parameters, disable commis-
sioning mode by writing a 0 (zero) to PNU890.
