stop the inverter.

Pr. 500 to Pr. 516

9999 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.
