Function assignment of external terminals
NOTES
Changing the terminal assignment using Pr. 178 to Pr. 184 "Input terminal function selection" may
affect the other functions. Please make setting 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) and
PID (X14).
When the X10 signal (FR-HC, FR-CV connection - inverter operation enable signal) is not set, the
MRS signal shares this function.
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 (7 speeds) 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.)
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 func-
tion 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 2 ms.
The response time of other signals is within 20 ms.
