P09.13 PID control selection
0x0000±0x1111
Ones place:
0: Continue integral control after the frequency
reaches upper/lower limit
1: Stop integral control after the frequency
reaches upper/lower limit
Tens place:
0: Same as the main reference direction
1: Contrary to the main reference direction
Hundreds place:
0: Limit as per the max. frequency
1: Limit as per 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. The ACC/DEC
is determined by P08.04 (ACC time 4).
