When the operation mode switching condition is specified (Setting 6 to 8)
Setting Mode Function
6 Switch-over
In response to the selection of the PU operation mode or
external operation mode from the operation panel or parameter
unit (FR-PU04), the operation command right can be changed
from the external operation to the PU operation or from the PU
operation to the external operation without stopping the
operation.
The operation in the switch-over mode is performed as described in the following table.
Operation Mode Switching Switching Control/Operation Status
External operation
PU operation
The operation mode is switched to the PU operation mode.
•
The rotation direction remains unchanged from the direction
of the external operation.
•
The speed remains unchanged from the setting of the
external operation. (Once power is switched "OFF" or a
reset is made, the stored setting of the external operation is
cleared to "0" and the operation stops.)
PU operation
external operation
The operation mode is switched to the external operation mode.
•
The rotation direction is determined by the input signal of the
external operation.
•
The speed is determined by the external setting signal.

PU operation
interlock
When the contact input terminal for the X12 signal has been
selected is "OFF", the operation mode is fixed to the external
operation mode.
To switch it to the PU operation mode, turn "ON" the X12 signal
and change the operation mode from the operation panel.
Turning the X12 signal "OFF" automatically returns the operation
mode to the external operation mode.
When the X12 signal is not selected, the MRS terminal acts as
the terminal having the function of the X12 signal.
