Outputs
Process controller
• In the Lenze setting, the process controller is deactivated.
• The activation is executed by selecting the operating mode in
.
• For a detailed functional description see FB
.
bPIDEnableInfluenceRamp
BOOL
Activate ramp for influencing factor
FALSE Influencing factor of the PID controller is ramped down to "0".
TRUE Influencing factor of the PID controller is ramped up to the value
nPIDInfluence_a.
bPIDOff
BOOL
Switch off I-component of the process controller
• In conjunction with the operating mode set in
(Lenze setting: "Off").
TRUE I-component of the process controller is switched off.
nPIDVpAdapt_a
