When Pr. 59 Remote function selection = "1" or "2", the functions of the RL, RM and RH signals are changed as given in the table.
∗2
When Pr. 270 Stop-on contact control selection = "1", functions of RL and RT signals are changed as in the table.
∗3
The OH signal turns ON when the relay contact "opens".
NOTE
Changing the terminal assignment using Pr.178 to Pr.184 (input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
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, FR-CV connection-inverter operation enable signal) is not set or when the PU operation
external interlock (X12) signal is not assigned with Pr.79 Operation mode selection set to "7", the MRS signal shares this
function.
Same signal is used to assign multi-speed (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.)
Switch the control method using external terminal (X18 signal) during an inverter stop. If control method between V/F
control and Advanced (General-purpose magnetic) flux vector control is switched during the operation, the actual
switchover does not take place until the inverter stops. In addition, if control method is switched to V/F control during
the operation, only second function becomes valid as V/F control and second function are selected simultaneously in
V/F control.
Turning the AU signal ON makes terminal 2 (voltage input) invalid.

Response time of each signal
The response time of the X10 signal and MRS signal is within 2ms.
The response time of other signals is within 20ms.
