Sinee EM500 - Integral Separation Function Description

EM500 Open-Loop Vector Control Inverter User Manual

The input terminal function “42: Process PID Integral Pause” can be used together for
remote control. If the function code setting is disabled (F09.20=100.00), the input
terminal function does not work. See Table 7-14 for details

●
PID setting variation time refers to the time required for the change from 0.0% to
100.0%. It is similar to an acceleration/deceleration function.If PID setting changes, the
actual setting value of PID will have a linear change to reduce the impact incurred upon
the system. After the initial value is set, the smooth setting will be invalid.

●
F09.22 is used for filtering of PID feedback. The filtering action is in favour of
reducing the interference impact upon the feedback, but causes the response performance
of the closed loop system of the process to go down.
F09.23 is used to filter PID output. The filter can reduce the possibility of sudden
change of inverter output frequency, but this can also reduce the response performance of
process closed loop system.
