No function
*1
When Pr. 59 Remote function selection = "1 or 2", the functions of the RL, RM and RH signals change as listed above.
*2
When Pr. 270 Stop-on contact/load torque high-speed frequency control selection = "1 or 3", the functions of the RL and RM 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 made valid during position control under vector control operation.
*6
Available only when used with the FR-A7AP (option).
REMARKS
⋅ 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) and PID (X14).
⋅ 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.
⋅ Use common terminals to assign multi-speeds (speed 7) and remote setting. They 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.)
⋅ When V/F switching (X18) signal and load pattern selection forward rotation reverse rotation boost (X17) signal are not
assigned, the RT signal shares this function. (Pr. 81 Number of motor poles = "12, 14, 16, 18, 20")
In this case, V/F control is controlled by the second function.
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.
