M ON IT OR D IG IT A L IN P U TS
The Hitachi VFD's have a monitor func�on that will display the status of the 24vdc digital inputs 1 thru 9 & A, B. Unlike the WJ200
the P1 has a GUI screen and supports up to (3) monitors on the main screen. By default, the digital input monitor should be located
on the botom of the main screen on power up. If the main screen does not show the digital input monitor, you can view it by
naviga�ng to the monitor parameter dA-51.
The P1's digital input monitor will display each input using a L or H that represents LOW or HIGH. The inputs on the monitor read
right to le� corresponding with digital inputs 1 thru 9 & A, B.
L will indicate the input is LOW which is off / not ac�ve.
H will indicate the input is HIGH which is on / ac�ve.
