User Manual of EM730 Series Inverter acceleration/deceleration time and operating time in the entire segment can be set separately. When the simple PLC is running, the operating frequency, operating direction, This is described below with the 13 th segment (the last segment) as an example. F08.12=50.00 : the operating frequency of 13 th segment is 50.00Hz. F08.43=31 : the operating direction in the 13 th segment is reverse, and the acceleration and deceleration are controlled based on the acceleration and deceleration time 4 (F15.07/F15.08). F08.44=5.0 : the operating time in the 13 th segment is 5.0s (F08.18=0 by default).
7.10 PID Function Parameter Group of F09 Group The EM730 series inverter has a process PID function, as described in this section. Process PID control is mainly for pressure control, flow control and temperature control. Fig. 7-27 Block Diagram of Process PID controlled by the system is fed back to the PID controller, and the output of the controller is adjusted after PID operation, thus forming one or more closed loops. This function is to make PID control is a kind of closed-loop control. The output signal (Out) of the object the output value (Out) of the object controlled by the system consistent with the set target value (Ref). The specific block diagram is shown in Fig. 7- 27.
The PID controller is used for control by calculating the control quantity with three calculation factors, i.e. proportion (P), integral (I) and differential (D), according to the difference between the set target (Ref) and feedback signal (Fdb). The features of each calculation factor are as follows: Proportion (P): proportional to the input error signal. When only proportional control is enabled, there are Proportional control is one of the simplest control modes. The output of the controller is 237 fifteenth segment
