*1 When [Pr. 59 Remote function selection
*2 When [Pr. 270 Stop-on contact, load torque high-speed frequency control selection = 1 (or 3) ], the functions of the RL and RT
signals change as listed above.
*3 The OH signal turns ON when the relay contact "opens".
*4 The FR-A7AX (16-bit digital input) is needed to externally input a stop position under orientation control.
*5 Servo ON is valid during position control under vector control operation.
*6 This parameter is valid when the FR-A7AP or FR-A7AL (option) is mounted.
*7 Changing the terminal assignment using [Pr. 178 to Pr. 189 Input terminal function selection] may affect the other functions.
Please make setting after confirming the function of each terminal.
*8 Same function can be assigned to two or more terminals. In this case, the logic of terminal input is OR.
*9 The priorities of the speed commands are in order of jog, multi-speed setting (RH, RM, RL, REX) and PID (X14).
*10 When the X10 signal (FR-HC, MT-HT, 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 = 7], the MRS signal shares
this function.
*11 Use common terminals to assign multi-speeds (7 speeds) and remote setting. These 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.
*12 When V/F switching (X18) signal and load pattern selection forward rotation reverse rotation boost (X17) signal are not
assigned in , the RT signal shares this function. ([Pr. 81 Number of motor poles = 12, 14, 16, 18, 20])

In this case, V/F control is valid in the second function.
