Appendix 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 563.)
 Function availability under each control method is shown as below:
: Available
: Not available
: Available only during position control set by parameter
 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 563.)
 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 characteristic 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.
