Function Code Parameter Name
FA-25 PID integral property
FA-25 determines whether to enable integral separation function and whether to stop
integral operation when PID output reaches limit.
If integral separation is enabled, when a DI set for function 38 "PID integral disabled"
is on, the integral operation becomes disabled. At this moment, only the P gain and
derivative time take effect.
If integral separation is disabled, no matter whether the DI set for function 38 "PID integral
disabled" is on, integral separation is inactive.
Function Code Parameter Name
FA-26 Detection level of PID feedback
loss
FA-27
Detection time of PID feedback
loss
FA-26 and FA-27 define the PID feedback loss detection function. When PID feedback is
smaller than the value set in FA-26 for time set in FA-27, AC drive detects Err31 and acts
as selected in ten thousands position in F9-49.
Function Code Parameter Name
FA-28 Selection of PID operation at
stop
FA-28: This function parameter determines whether to continue PID operation when the
AC drive stops.
