Function assignment of external terminal and control
(1) Input terminal function assignment
Using Pr. 178 to Pr. 182, set the functions of the input terminals.
Refer to the following table and set the parameters:
∗1 When Pr. 59 Remote function selection ≠ "0", the functions of the RL, RM and RH signals are changed as given in the table.
∗2 The OH signal turns ON when the relay contact "opens".
(2) 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.

NOTE
Changing the terminal assignment using Pr.178 to Pr.182 (input terminal function selection) may affect the other functions.
Make setting after confirming the function of each terminal.
One function can be assigned to two or more terminals. In this case, the terminal inputs are ORed.
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 (7th speed) and remote setting. They cannot be set individually.
(Same signal is used since multi-speed (7th speed) setting and remote setting are not used to set speed at the same
time.)
When V/F control is selected by V/F switchover (X18 signal), second function is also selected at the same time.
Control between V/F and General-purpose magnetic flux can not be switched during operation. In case control is
switched between V/F and General-purpose magnetic flux, only second function is selected.
Turning the AU signal ON makes terminal 2 (voltage input) invalid.
