User Manual of EM760 High-Performance Inverter PID settings are determined in conjunction with the setting of the function code F09.00. The EM760 series inverter has a multi-segment PID setting function, and its switching conditions are mainly dependent on the input functions “15: multi-segment PID terminal 1” and “16: multi-segment PID terminal 2”, as detailed in the table below. Table 6-8 Details of Multi-segment PID Setting Function The upper and lower limits of the feedback voltage can be used for automatic material cutoff detection in winding applications. They represent the upper and lower limits of material cutoff, respectively.
Due to the particularity of winding applications, F09.35 and F09.36 can be used to reflect the real sensor boundaries, which is more conducive to the system stability.
