Chapter 12 Description of Parameter SettingsC2000
12.1-08-4
Pr. 00-04 = 10 (Display PID feedback (b) (%)).
Pr. 01-12 Acceleration Time is set as according to actual conditions.
Pr. 01-13 Deceleration Time is set as according to actual conditions.
Pr. 00-21 = 0 to operate through the digital keypad.
Pr. 00-20 = 0, the digital keypad controls the set point.
Pr. 08-00 = 1 (Negative PID feedback from analog input)
ACI analog input Pr. 03-01 = 5, PID feedback signal.
Pr. 08-01–08-03 is set according to actual conditions:
If there is no vibration in the system, increase Pr. 08-01 (Proportional Gain (P))
If there is no vibration in the system, decrease Pr. 08-02 (Integral Time (I))
If there is no vibration in the system, increase Pr. 08-03 (Differential Time(D))
Refer to Pr. 08-00 to Pr. 08-21 for PID parameter settings.
Proportional Gain (P)
Default: 1.0
Settings 0.0–500.0
1.0: Kp gain is 100%; if the setting is 0.5, Kp gain is 50%.
Determines the deviation response of Proportional gain (P). Eliminates the system error; usually
used to decrease the error and get faster response speed. it also reduces the steady-state error.
But if you set the value too high, it may cause system oscillation and instability.
If you set the other two gains (I and D) to zero, proportional control is the only effective
parameter.
Integral Time (I)
Default: 1.00
Settings 0.00–100.00 sec.
0.00: No integral
Use the integral controller to eliminate the error during stable system operation. The integral
control does not stop working until the error is zero. The integral is affected by the integral time.
