Note 1. 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 2. An automatic reset fuse is provided to protect output. If the fuse is activated for overcurrent, it will auto-
matically reset after a fixed period of time has lapsed without current flowing (supported by Servo Driv-
ers with software version “r.0037” or later).
