Omron OMNUC R88D-WT15HF User Manual

2-70
Note 2. The inputs at pins 40 to 46 and the outputs at pins 25 to 30 can be changed by parameter
settings. The settings in the diagram are the defaults.
Note 3. Pins 2, 4, 21, and 22 are for use with an absolute encoder.
Note 4. An automatic reset fuse is provided to protect output. If the fuse is activated for overcurrent, it
will automatically reset after a fixed period of time has lapsed without current flowing (sup-
ported by Servo Drivers with software version “r.0037” or later).
