REMARKS
 The signals other than the ROH signal can be assigned to two or more terminals. In this case, the logic of terminal input is OR.
If the ROH signal, which is assigned to several terminals, turns OFF once, the converter remains tripped until the ROH signal
turns ON at all the terminals.
NOTE

Changing the terminal assignment using Pr. 3 to Pr. 7 (input terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.

Function
Turning ON this signal stops the converter.
Operation can be changed using Pr. 8.
Monitor item at PU (operation panel and parameter unit)
and terminals FM and AM can be switched by a
combination of ON/OFF of these signals.
Turning ON this signal resets the converter.
The signal is input from the external thermal relay.
Turning ON the signal stops the converter operation.
(E.OHT)
Operation can be changed using Pr. 9.
The ROH signal turns OFF and the converter trips
(E.IOH) when overheating from the inrush resistance
occurs or the filter capacitor (FR-HCC2) is detected to
be swollen .
 Filter capacitor alarm detector is only available for 560K.
