Outputs
nAct_a
INT
Speed or actual sensor value (actual process value)
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
• Display parameter: C00830/61
bIOff
BOOL
Switch off I-component of process controller
• Changes can be done online.
• Display parameter: C00833/77
TRUE I-component of the process controller is switched off.
bInAct
BOOL
Deactivate process controller temporarily
• Changes can be done online.
• Display parameter: C00833/76
Note: This input is not connected with the application NCTRL.
TRUE Process controller is deactivated, the internal PID component is
switched off.
nInflu_a
INT
Limitation of the influencing factor in percent
• nInflu_a serves to limit the influencing factor of the PID controller contained in
the FB to a required value (- 199.99 % ... + 199.99 %).
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
• Display parameter: C00830/64
bActivateRamp
BOOL
Activate ramp for influencing factor
• Display parameter: C00833/106
TRUE Influencing factor of the PID controller is ramped up to the nInflu_a
value.
FALSE Influencing factor of the PID controller is ramped down to "0".
bISet
BOOL
Accept I component nISet_a in PID controller
TRUE The value at the input nISet_a is accepted in the PID controller.
nISet_a
INT
Selection of I component of PID controller
• With a TRUE signal at bISet, the assigned value is accepted in the PID controller.
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %

Value/meaning
nOut_a
INT
Output signal
• Internal limitation to ±32767 (±199.99 %)
• Scaling: 16384 ≡ 100 %
bActEqSet
INT
Status output "Setpoint and actual value are identical"
TRUE Setpoint and actual value are identical, i.e. no system deviation
available.
nPIDOut2_a
INT
PID controller output without influencing factor nInflu_a
•The inputs bActivateRamp and nInflu_a do not have any effect here, the limited
PID output value influenced by the internal ramp times is output.
• There is no connection with the additive input nNSet_a.
• Scaling: 16384 ≡ 100 %
nPIDOut_a
INT
PID controller output with influencing factor nInflu_a
• There is no connection with the additive input nNSet_a.
• Scaling: 16384 ≡ 100 %
• Display parameter: C00245
nInfluenceOut_a
INT
Current influencing factor ("ramp status") on the PID output value
• Scaling: 16384 ≡ 100 %
