REMARKS
Same function can be assigned to two or more terminals. In this case, the logic of terminal input is OR.
The priorities of the speed commands are in order of jog > multi-speed setting (RH, RM, RL, REX) > PID (X14).
When the X10 signal (FR-HC, MT-HC, FR-CV connection - inverter operation enable signal) is not set or when the PU
operation external interlock (X12) signal is not assigned at the Pr. 79 Operation mode selection setting of "7", the MRS signal
shares this function.
Same signal is used to assign multi-speeds (7 speeds) and remote setting. They cannot be set individually.
(Same signal is used since multi-speed (7 speeds) setting and remote setting are not used to set speed at the same time .)
CAUTION
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Also
check that wiring is correct, since the terminal name and the signal function became different. Please make setting after
confirming the function of each terminal.
