176
b5-40
(17FH)
Frequency Reference Monitor
Content during PID 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.
Default: 0
Min: 0
Max: 1
176
b5-47
(17DH)
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 (Zero limit if the reverse operation is
prohibited by b1-04)
Default: 1
Min: 0
Max: 1
177
<5> Default setting is dependent on PID setpoint scaling (b5-20).
<6> Default setting value varies by the drive model (o2-04).
<10> Default setting is determined by the control mode (A1-02).
