Function assignment of external terminal and control
4
PARAMETERS
(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. 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-drive unit 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. These 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.)
Turning the AU signal ON makes terminal 2 (voltage input) invalid.
