Possible Cause(s)
The Inverter does not support a
3G3AX-MX2-PRT-E (Refer to 1-1-2 Inverter
Support)
The Option Board connector is damaged
The Inverter encountered a fatal error during
Operation.
The Option Board node address was set using
the set-slave address functionality of your
PROFIBUS master or diagnostic tool, but the
Inverter password function is set.
The user program requested a trip by setting
the external trip bit of the conventional module
operation command.
If the Option Board is correctly configured, the RUN indicator will be ON and
the ERR indicator OFF. The table below shows the indicator and display pat-
terns caused by configuration errors.
Possible Cause(s)
One of the configuration parameters P160 -
P179 has been rejected by the Inverter.
Your Inverter version has not been properly
verified with this version of the
3G3AX-MX2-PRT-E (The PROFIBUS node
address in the Inverter is invalid or absent).
Your Inverter version has not been properly
verified with this version of the
3G3AX-MX2-PRT-E (Some Option Board
parameters in the Inverter are invalid or
absent).
Corrective Action
Replace the Inverter.
Replace the Option Board.
Restart the Inverter. If the problem persists,
replace the Inverter.
Restart the Option Board. If you need to set the
Option Board node address, first clear the
Inverter password (Refer to section 3-6-25 in
@
the MX2-A Inverter user's manual).
Check and correct all items in accordance with
the user program.
Corrective Action
Check (and correct) the following items:
• Is one of the parameters P160 - P179
specifying a Modbus register that does not
exist?
• If one of the parameters P160 - P169 is
specifying a double-word Modbus register:
Are both the high- and low-words specified
in sequence by two consecutive parame-
ters?
• If one of the parameters P170 - P179 is
specifying a double-word Modbus register:
Are both the high- and low-words specified
in sequence by two consecutive parame-
ters?
• Is a Modbus register specified twice in the
output parameter registers P160 - P169?
• 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.)
