Register Numbers

All accessible inverter parameters are referenced by their register number as defined in Table 18 and
can be conveniently referenced in the configuration studio (section 5.6) and the embedded web server
(section 6.2.3). Note that the register list is not exhaustive, the registers may not exist for all inverters,
and the register data contents may vary depending on the inverter. The register numbers are used when
accessing and configuring registers via an Ethernet protocol. Information regarding the command
registers (1 to 7) and monitor registers (100 and 101) are included in this manual for user convenience,
but more information can be found in the inverter user manual "Mitsubishi inverter protocol" section.
Monitor registers 201 to 254 are documented in the inverter user manual "Monitor description list". For 4
information regarding the remaining inverter parameters, refer to the inverter user manual "Parameter
List".
Note that not all of the available registers that exist in the interface card's register map have
corresponding parameters that exist in the inverter. In other words, if a read from or write to a register
that does not correspond to an existing inverter register/parameter takes place, the read/write may be
successful (depending on the specific register accessed; refer to section 4.2), but the data will have no
meaning. This feature is beneficial in situations where the accessing of non-contiguous registers can be
made more efficient by accessing an all-inclusive block of registers (some of which correspond to
inverter parameters and some of which do not), while only manipulating those in your local programming
that are known to exist.
