Reverse Operation Selection
2 by PID Output
Reverses 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

b6: Dwell Function
Use b6 parameters to configure dwell function operation.
b6-01 Dwell Reference at Start
The Dwell function is used to temporarily hold the frequency
when driving a motor with a heavy load.
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.

<1> Default setting value is dependent on parameter A1-02, Control Method Selection. The value shown is for A1-02 = 2-OLV control.
<2> A coasting motor may require a braking resistor circuit to bring the motor to a stop in the required time.
<3> Default setting value is dependent on parameter A1-02, Control Method Selection. The value shown is for A1-02 = 0-V/f Control.
<4> Default setting value is dependent on parameter o2-04, Drive Model Selection.
<5> Available in drive software versions PRG: 1020 and later.
<6> Parameter can be changed during Run.
<7> Default setting is dependent on parameter b5-20, PID Setpoint Scaling.
