User Manual of EM730 Series Inverter to 100.0%, similar to the acceleration and deceleration time function. When the PID setting The PID setting change time refers to the time required for the setting to change from 0.0% changes, the actual PID setting will change linearly, thus reducing the impact of sudden changes on the system. Smoothing is invalid during the initial setting. The setting will change from the current feedback value during the start. F09.22 is used to filter the PID feedback. This is helpful to reduce the impact of interference on the feedback, but will cause the decline of the response performance of the process closed-loop system.
output frequency of the inverter, but will also cause the decline of the response performance of F09.23 is used to filter the PID output. This is helpful to reduce the sudden changes in the the process closed-loop system. feedback disconnection. Depending on the nature of the feedback sensor, the settings are The function of PID feedback disconnection detection is to prevent galloping caused by different. If the 0.0% type sensor is fed back at the time of disconnection, the lower limit of PID feedback disconnection detection (F09.25) needs to be set to an appropriate value.
