MONITOR DIGITAL INPUTS
The Hitachi VFD’s have a monitor function 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
bottom of the main screen on power up. If the main screen does not show the digital input monitor, you can view it by navigating 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 left corresponding with digital inputs 1 thru 9 & A, B.
L will indicate the input is LOW which is off / not active.
H will indicate the input is HIGH which is on / active.
Hitachi P1 Digital Input Monitor parameter = dA-51
The image below is a reference image to the P1 digital input monitor. This example shows digital input 5 is the only active digital input.
Again, the screen reads right to left, digital input 1 is the 1
st
line from the right.
