1.
It takes about one (1) second from the servo ON to the
time when the robot is actually ready to work.
Therefore, program so that the RUN signal, etc., can turn
on only after the SV_RDY signal turns on.
2.
To prevent an internal damage, the servo cannot be
turned on about 4.5 seconds after it is turned off. To
turn the servo on again, wait at least five (5) seconds
after the SVST_A ~ SVST_B signal turns off.
