VFD-L-I Series
Revision July 2009, SW V1.1 4-43
07-13
PID Offset
Unit: 0.01
Settings 0.00 to 400.00 Factory Setting: 20.00
It needs to set Pr.07-12 to enable this function.
07-14
Modulation Time of P
Unit: 1
Settings 0 to 1000 (*20ms) Factory Setting: 1000
This parameter determinates the required time for proportional gain to reach Pr.07-07 setting.
It needs to set Pr.07-12 to enable this function.
07-15
Max. Feedback Signal
Unit: 0.01
Settings
0.00 to 100.00%
Factory Setting: 80.00
This parameter determines the max. output value of the PID feedback signal.
07-16
Min. Feedback Signal
Unit: 0.01
Settings 0.00 to 100.00% Factory Setting: 20.00
This parameter determines the min. output value of the PID feedback signal.
07-17 Treatment of the Erroneous Feedback Signals
Factory Setting: 1
Settings 0 difference of PID setting frequency and feedback is 0 (integral value
is not changed)
1 difference of PID setting frequency and feedback is 0 (integral
value=0)
2 stop the AC motor drive
This parameter selects the operation of the drive upon a loss of PID feedback signal.
07-18
Feedback Signal Detection Time
Unit: 1
Settings 0 to 1000(*20ms) Factory Setting: 150
This parameter defines the detection time for the loss of a feedback analog signal. It also can
be used in the application that the system feedback signal is very slow. (setting 0.0: disable)
07-19 PID Target Value Unit: 0.01
Settings 0.00 to 10.00V Factory Setting: 5.00
When Pr.07-05 is set to 3, the PID target value is the setting of Pr.07-19.
