Description
frequency achieves the upper and low limit; the
integration shows the change between the
reference and the feedback unless it reaches
the internal integral limit. When the trend
between the reference and the feedback
changes, it needs more time to offset the
impact of continuous
integration will change with the trend.
1: Stop integral adjustment when the frequency
reaches the upper and low 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 setting direction; if the
output of PID adjustment is different from the
current running direction, the internal will output
0 forcedly.
1: Opposite to the setting direction
Hundreds place:
0: Limit to the maximum frequency
1: Limit to A frequency
Thousands place:
0: A+B frequency, buffer ACC/DEC is invalid
for the main reference A frequency source
1: A+B frequency, buffer ACC/DEC is valid for
the main reference A frequency source and the
ACC/DEC is determined by time 4 of P08.04.
