No function
*: When Pr. 59 = "1" or "2", the functions of the RL, RM, RH and RT signals change as listed above.
**: Operated when the relay contact "opens".
Note: 1. One function can be assigned to two or more terminals. In this case, the terminal inputs are
OR’ed.
2. The speed command priorities are higher in order of jog, multi-speed setting (RH, RM, RL) and
AU.
3. When HC connection (inverter operation enable signal) is not selected, the MRS terminal shares
this function.
4. Use common terminals to assign the multi-speeds (7 speeds) and remote setting. They cannot
be set individually.
(Common terminals are used since these functions are designed for speed setting and need not
be set at the same time.)
5. When FR-HC connection inverter operation enable (X10) signal is not assigned, the MRS
terminal shares this function.
6. When "7" is set in Pr. 79 and the PU operation external interlock (X12) signal is not assigned, the
MRS signal acts as this function.
7. When the load pattern selection forward/reverse rotation boost (X17) signal is not assigned, the
RT signal shares this function.
