6.4.18.9 PID controller
BI: Enable PID controlle
r
PID mode Allows user to enable/disable the PID controller. Setting to 1 enables the PID
controller. Setting 1 automatically disables normal ramp times set in P1120 and P1121 and
the normal fre

oints.
PID mode
Configuration of PID controller.
0 PID as setpoint
1 PID as trim
CI: PID setpoint
Defines set

oint source for PID set
p
oint in
p
ut.
CI: PID trim source
Selects trim source for PID setpoint. This signal is multiplied by the trim gain and added to
the PID set
p
oint.
Ramp-up time for PID setpoint
Sets the ram

time for the PID set
p
oint.
Ramp-down time for PID setpoint
Sets ram
p
-down time for PID set
p
oint.
CI: PID feedback
Selects the source of the PID feedback si

Max. value for PID feedback
Sets the u

CO: PID error
Displays PID error (difference) signal between setpoint and feedback signals in [%].
PID derivative time
Sets PID derivative time.
P2274 = 0:
The derivative term does not have any effect (it applies a gain of 1).
PID proportional gain
