User Manual of EM730/EM730E Series Inverter 100.00%. F09.02=5: PULSE high-frequency pulse (X5) The set percentage of PID is directly dependent on the HDI (percentage). For the details of AI1-AI2 and X5, see the description of F00.04. When used as the PID setting, the percentage will directly turn the set value, and the maximum output is 100.00%. F09.02=6: communication setting The PID feedback percentage is directly dependent on the communication (percentage).
If the master-slave communication (F10.05=1) is enabled and the inverter works as the slave (F10.06=0), the specific feedback percentage is “700FH (master-slave communication setting) * F10.08 (slave receiving proportional coefficient)”, and the 700FH data range is -100.00% to 100.00%, as detailed in Table 12-31. For the general communication (F10.05=0), the specific feedback percentage is “7005H (communication setting of process PID feedback)”, and the 7005H data range is -100.00% to 100.00%, as detailed in Table 12-31. The process PID action mode depends jointly on the setting of the function code F09.04 and the status of the input function “44:
PID positive/negative action switching”, as detailed in Table 7-14. Table 7-14 Description of PID Positive/Negative Action Note: The deviation in PID control is usually “setting - feedback”. When the feedback signal is greater than the PID setting, the output frequency of the 220 Function Default Function code name Parameter description Unit Attribute code setting F09.04 PID positive and negative action selection 0: positive 1: negative 0 〇 F09.04 44: PID positive/negative Mode of action Note switching 0 0 Positive action Both the deviation and output are positive. 0 1 Negative action The deviation is positive and the output is negative.
1 0 Negative action The deviation is positive and the output is negative. 1 1 Positive action Both the deviation and output are positive.
