9.2 Parameters (functions) and instruction codes
under different control methods
*1 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 483.)
*2 Function availability under each control method is shown as below:
: Available
ï‚´: Not available
*3 For "parameter copy", "parameter clear", and "all parameter clear", "" indicates the function is available, and "" indicates the function is not
available.
*4 Communication parameters that are not cleared by parameter clear or all clear (H5A5A or H55AA) via communication.
*5 When a communication option is installed, parameter clear (lock release) during password lock (Pr.297 ≠"9999") can be performed only from the
communication option.
*6 Reading and writing via the PU connector are available.
Symbols in the table indicate parameters that operate when the options are connected.
