the feedback changes, it needs more time to
offset the impact of continuous working and the
integration will change with the trend.
1: Stop integral control after the frequency
reaches upper/lower limit. If the integration
keeps stable, and the trend between the
reference and the feedback changes, the
integration will change with the trend quickly.
Tens place:
0: The same with the set direction. If the output
of PID control is different from the current
running direction, 0 will be output forcedly.
1: Contrary to the set direction. If the output of
PID control is different from the current running
direction, the closed-loop regulation output
opposite to the current running direction is
executed.
Hundreds place:
0: Limit based on the max. frequency
1: Limit based on A frequency
Thousands place:
0: A+B frequency, ACC/DEC of main reference A
frequency source buffering is invalid
1: A+B frequency, ACC/DEC of main reference A
frequency source buffering is valid, ACC and
DEC are determined by P08.04 (ACC time 4)
