Corrective Action
One of the configuration parameters
P160 - P179 has been rejected by the
Inverter.
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 regis-
ter: Are both the high- and low-words
specified in sequence by two consecu-
tive parameters?
• If one of the parameters P170 - P179 is
specifying a double-word Modbus regis-
ter: Are both the high- and low-words
specified in sequence by two consecu-
tive parameters?
• 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).
See section B-4-2 of the MX2
Inverter user's manual.
See section 4-4 Register Num-
ber List RX Inverter user's
manual.
• Is one of the output parameters P160 -
P169 specifying a Modbus register of
which the parameter is not run-mode
editable?
Refer to section 3-2-3 of the
MX2 Inverter user's manual.
Refer to Appendix 1 of the RX-
Inverter user's manual.
