User Manual of EM760 High-Performance Inverter The set percentage of PID is directly dependent on the HDI (percentage). See 6.5.3 for details of X7 serving as high-speed pulse input. When serving as PID setting, the percentage is directly given, 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%.
● For the general communication (F10.05=0), the specific feedback percentage is “7005H (communication setting ofprocess PID feedback)”, and the 7005H data range is -100.00% to 100.00%. The process PID action mode depends jointly on the setting ofthe function code F09.04 and the status of the input function “44: PID positive/negative action switching”. The relation details when positive and negative actions don’t follow the command direction are as described below. Table 6-3 PID Positive/Negative Action - Description 1 The relation details when the positive and negative actions follow the command direction areas shown below.
