Switch-over mode
You can select between PU operation, external operation and computer link operation (when FR-A5NR option
is used).
Operation Mode Switching Switching Operation/Operating Status
External operation to PU
operation
1) Select the PU operation mode.
•
Rotation direction is the same as that of external operation.
•
Set frequency is as set by the potentiometer (frequency setting potentiometer). (Note that
the setting will disappear when power is switched off or the inverter is reset.)
External operation to computer
link operation
1) Mode change command to computer link mode is transmitted from the computer.
•
Rotation direction is the same as that of external operation.
•
Set frequency is as set by the potentiometer (frequency setting potentiometer). (Note that
the setting will disappear when power is switched off or the inverter is reset.)
PU operation to external
operation
1) Press the external operation key of the parameter unit.
•
Rotation direction is determined by the external operation input signal.
•
Set frequency is determined by the external frequency setting signal.
PU operation to computer link
operation
1) Mode change command to computer link mode is transmitted from the computer.
•
Rotation direction and set frequency are the same as those of PU operation.
Computer link operation to
external operation
1) The switch-over command to the external mode is sent from the computer.
•
Rotation direction is determined by the external operation input signal.
•
Set frequency is determined by the external frequency setting signal.
Computer link operation to PU
operation
1) Select the PU operation mode with the operation panel or parameter unit.
•
Rotation direction and set frequency are the same as those of computer link operation.

PU operation interlock
When the PU operation interlock signal is switched off, the operation mode is forcibly changed to the external
operation mode. This function prevents the inverter from being inoperative by the external command if the
mode is accidentally left unswitched from the PU operation mode.
1) Preparation
•
Set "7" in Pr. 79 (PU operation interlock).
•
Using any of Pr. 180 to Pr. 186 (input terminal function selection), allocate the terminal used to
input X12 (PU external interlock signal).
Refer to page 138 for Pr. 180 to Pr. 186 (input terminal function selection).
•
When the X12 signal is not assigned, the function of the MRS signal changes from MRS (output stop) to
PU external interlock.
Note: When terminal assignment is changed using Pr. 180 to Pr. 186, the other functions may be affected.
Check the functions of the corresponding terminals before making setting.
2) Function
X12 (MRS)
Signal
Function/Operation
ON
Output stopped during external operation.
Operation mode can be switched to PU operation mode.
Parameter values can be rewritten in PU operation
mode.
PU operation allowed.
OFF
Forcibly switched to external operation mode.
External operation allowed.
Switching to PU operation mode inhibited.
