Pr. 116 PID Feedback Terminal Selection Factory Setting: 00
Settings 00 Input positive PID feedback, PV from AVI (0 to 10V)
01 Input negative PID feedback, PV from AVI (0 to 10V)
02 Input positive PID feedback, PV from ACI (4 to 20mA)
03 Input negative PID feedback, PV from ACI (4 to 20mA)
Select an input terminal to be the PID feedback. Please verify the PID feedback position
is different from the Frequency Set Point position.
Negative feedback = positive targeted value – detective value. Positive feedback =
negative targeted value + detective value.
Pr. 117 Proportional Gain (P)
Factory Setting: 1.0
Settings 0.0 to 10.0
This parameter determines the feedback loop Gain. If the gain is large, the response
will be strong and immediate (If the gain is too large, vibration may occur). If the gain is
small, the response will be weak and slow.
When I=0.0 and D=0.0, it is only used for proportional control.
Pr. 118 Integral Time (I) Factory Setting: 1.00
Settings 0.01 to 100.00 sec Unit: 0.01sec
0.00 disable
This parameter determines the speed of response for the PID feedback loop. If the
integral time is long, the response will be slow. If the integral time is short, the response
will be quick. Be careful not to set (I) too small, since a rapid response may cause
oscillation in the PID loop.
