Driver RUN command (RUN)
When IB00104 turns ON, the speed
reference output mode starts.
When the acceleration command (IB00105)
turns ON, a speed reference of 50% is
output for the acceleration time constant
(ACC).
When IB00105 turns OFF, the deceleration
time constant (DEC) causes deceleration
stop (a speed reference of 0% is output).
