SJ100/L100 / PID / 4 SJ100/L100 series inverters have integrated PID control, which is indicated by the dotted line in Fig. 2-1. You can use PID control by setting a target value and providing a feedback signal. The example in Fig. 2-2 shows a connection diagram for ventilation flow control in a fan...

Page 6 - -2 PID Gain Adjustments & Control Characteristics; Decrease Integration time (T

SJ100/L100 / PID / 6 2-2 PID Gain Adjustments & Control Characteristics The optimal gain factors of PID vary from condition to condition, and from system to system. That means it is necessary to set those parameters by taking into account the individual control characteristics of your particular...
