PID control selection
0x0000–0x1111
Ones:
0: Continue integral control after the
frequency reaches upper/lower limit
1: Stop integral control after the
frequency reaches upper/lower limit
Tens:
0: The same with the main reference
direction
1: Contrary to the main reference
direction
Hundreds:
0: Limit as per the max. frequency
1: Limit as per A frequency
Thousands:
0: A+B frequency, acceleration
/deceleration of main reference A
frequency source buffering is invalid
1: A+B frequency, acceleration/
deceleration of main reference A
frequency source buffering is valid,
acceleration/deceleration is determined
by P08.04 (acceleration time 4).
