0: Display the frequency reference (U1-01) after PID compensation has been
added.
1: Display the frequency reference (U1-01) before PID compensation has been
added.
Reverse operation selection when b5-01 = 3 or 4.
0: Zero limit when PID output is a negative value.
1: Reverse operation when PID output is a negative value
(Zero limit if the reverse operation is prohibited by b1-04).
Parameters b6-01 and b6-02 set the frequency to hold and the time to maintain
that frequency at start.
Parameters b6-03 and b6-04 set the frequency to hold and the time to maintain
that frequency at stop.
Sets the speed reduction gain applied at a torque reference of 100%. Set as a
percentage of motor base speed.
