External trip (EXT)
This function can be used to force the Inverter into a trip situation which
is switched by an external input, i.e. PLC or relay contact.
When the EXT terminal is switched ON, the inverter trips on an E12 error and the outputis switched OFF.
Assign 12(EXT) to an intelligent input terminal.
The trip will not be canceled when the terminal is turned OFF.
To cancel the trip, the reset signal must be applied or the Inverter switched OFF and ON again at the supply.
3 Wire input function(STA, STP, F/R)
This function is used when a momentary push start/stop control is
required.
Set the operation command selection A002 to control terminal (01).
Assign 20 (STA), 21 (STP) and 22 (F/R) to three of the intelligent input terminals, and the operation becomes
possible as follows. When the terminal is assigned STP terminal, FW terminal and also RV terminal become
invalid. If all three inputs are not assigned this function will not operate.
The FW terminal and RV terminal become redundant when the 3 wire control is assigned to the intelligent input
terminals. Output from the 3 wire control terminal is as follows;
STA
ON
OFF
OFF
ON
Forward
Reverse
