6. Description of Parameters
- 108 -
Function Code Parameter Name Setting Range Default
FA-25
PID integral property Units position: Integral separation
0: Disabled
1: Enabled
00
Tens position: Whether to stop integral
operation when the PID output reaches
the limit
0: Continue integral operation
1: Stop integral operation
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 Setting Range Default
FA-26
Detection level of PID feedback
loss
0.0%: No detection
0.1% to 100.0%
0.0%
FA-27
Detection time of PID feedback
loss
0.0s to 20.0s 0.0s
FA-26 and FA-27 dene 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 Setting Range Default
FA-28
Selection of PID operation at
stop
0: Disabled
1: Enabled
0
FA-28: This function parameter determines whether to continue PID operation when the
AC drive stops.
