For example:
if you want to enter a value
of 10,000 PPR, open the PPR
drop-down menu, keying in 10,000.
Then, select the desired value with a
mouse click in the drop-down menu.

When you select one of the output
channels (channel A, for example), this
inversion
will switch the differential outputs from
A - nA to nA - A.
This option can make physical connection
of the encoder to the PLC / Driver.

During Power-On programming (encoder powered-up), the PR90
should NEVER be programmed with the machine in operation.
At the time of programming information can be lost until programming has
finished, and this could cause unexpected behaviour in the machine
connected to the encoder.

PR90 / PR90H
The PR90 encoder considers TTL from 4.5 to
10Vdc and HTL from 11 to 30 Vdc. If input
values are below the HTL limit, the PR90 encoder
.
will automatically switch output to TTL.
