F147 [FL Relay delay]
Delay for FL Relay 0.0 to 60.0 s 0.0 s
This parameter introduce a delay on FL output signal relay.

[No PID]: PID disabled
[PID by VIA]: Enabled (feedback source is VIA)
[PID by VIB]: Enabled (feedback source is VIB)
Parameter F360 is used to enable PID control and define the source of the feedback signal.
The PID source is defined by the setting of parameter [Frequency mode sel] (FMOd) (see page 77
).
Parameter [Freq band det range] (F167) can be adjusted to command a drive relay to signal when the PID setpoint and
feedback are in agreement (see page 115
).
F362 [PID Prop Gain]
PID Proportionnal Gain
0.01 to 100.0% 0.30%
Parameter F362 adjusts the proportional gain applied during PID control. The speed change applied to the motor is a correc-
tional value proportional to the product of this parameter’s setting and the process error (deviation between the setpoint and the
feedback value).
A higher setting of F362 provides a fast response to a process error but may also result in instability such as hunting. The
diagram below illustrates the effect produced by adjusting F362.
F363 [PID Integral Gain]
0.01 to 100.0 0.20
Parameter F363 adjusts the integral gain applied during PID control. Any residual process errors that remain after correction
by the proportional gain are cleared to zero over time by the integral gain function.
A higher setting of F363 provides a fast response to a process error but may also result in instability such as hunting. The
diagram below illustrates the effect produced by adjusting F363.
The integral gain value can be set to zero by setting a logic input to function 65. For more information, see table on page 91 and
parameters [LI F selection] (F111), [LI R selection] (F112), [LI RES selection] (F113), page 90
, and
[VIA LI selection] (F118), page 90
