Note: Either "3" or "4" may be set to select the PU/external combined operation.
These settings differ in starting method.
( 1 ) Switch-over mode
During operation, you can change the current operation mode to another operation
External operation to PU
PU operation to external
( 2 ) PU operation interlock
PU operation interlock forces the operation mode to be changed to the external
operation mode when the MRS signal switches off. This function prevents the inverter
from being inoperative by the external command if the mode is accidentally left
unswitched from the PU operation mode.
y Set "7" in Pr. 79 (PU operation interlock).
y Set the terminal used for MRS signal input with any of Pr. 180 to Pr. 183 (input
terminal function selection).
Refer to page 145 for Pr. 180 to Pr. 183 (input terminal function selection).
Note: When terminal assignment is changed using Pr. 180 to Pr. 183, the other
functions may be affected.
Check the functions of the corresponding terminals before making settings.
Switching Control/Operating Status
1) Operate the control panel keys to select the PU operation
Rotation direction is the same as that of external operation.
Set frequency is the same as the external frequency setting
signal value. (Note that the setting will disappear when
power is switched off or the inverter is reset.)
1) Operate the control panel keys to select the external operation
Rotation direction is determined by the external operation
Set frequency is determined by the external frequency
