*1 Only a brake resistor should be connected to terminal PR. Doing so may damage the
brake unit.
*2 BUE-SD is connected with a jumper in the initial status. Remove a jumper when
using this signal. (When terminals are open, brake unit is not operated.)
*3 Do not connect terminals SD, PC and MSG each other or to the ground. Doing so
may damage the brake unit.
For sink logic (initial status), terminal SD acts as the common terminal of contact
input. For source logic (initial status), terminal PC acts as the common terminal of
contact input.
