A.3 Parameters (functions) and instruction codes under
different control methods
Instruction codes are used to read and write parameters in accordance with the Mitsubishi inverter
protocol of RS-485 communication.
(For RS-485 communication, refer to page 5-635.)
Function availability under each control method is shown as below:

: Available
×: Not available
Δ: Available only during position control set by parameter
—: No information for the function available
If function availability differs between using induction motors with an encoder and using PM
motors with a resolver, the function availability using PM motors with a resolver is described in
parentheses. Also, a PM motor with a resolver is not available under the torque control.
For "parameter copy", "parameter clear", and "all parameter clear":
"

" indicates the function is available, and
"×" indicates the function is not available.
$
These parameters are not cleared by the parameter clear (all parameter clear) command, which
are sent through RS-485 communication. (For RS-485 communication, refer to page 5-635.)
%
When a communication option is installed, parameter clear (lock release) during password lock
(Pr. 297
≠
"9999") can be performed only from the communication option.
&
Available when the IPM motor MM-CF series is used and the low-speed range high-torque char-
acteristic is enabled (Pr. 788 = "9999 (initial value)").
'
Reading and writing via the PU connector are available.
Symbols in the table indicate parameters that operate when the options are connected.
