Parameter
Identifier/data type Information/possible settings
nNSet_a
INT
Speed setpoint
nAdapt_a
INT
Reduction of the gain (nVp) by the value applied (in %)
• Internal limitation to ±32767
• Changes can be done online.
Example:
When nVp = 2.0 and nVpadapt = 75 % ((75/100) x 16384 = 12288), the gain factor
results in: 2.0 x 12288 = 24576
nSet_a
INT
Sensor setpoint (process setpoint) in the operating mode nMode = 1 and 3
• Internal limitation to ± 199.9 %
Process setpoint in operating mode nMode = 2
• Internal limitation to ± 199.9 %
nAct_a
INT
Speed or actual sensor value (actual process value)
• Internal limitation to ± 199.9 %
bInAct
BOOL
Deactivate process controller temporarily
• Changes can be done online.
Note: This input is not connected with the application NCTRL.
True Process controller is deactivated, the internal PID-component is
switched off.
bIOff
BOOL
Switch off the I-component of the process controller
• Changes can be done online.
True I-component of the process controller is switched off
nInfluence_a
INT
• Internal limitation to ±32767
• nInfluence_a serves to limit the influencing factor of the PID controller contained
in the FB to a required value (- 199.9 % ... + 199.9 %).
nEnableInfluenceRamp
INT
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".
Identifier/data type Value/meaning
nOut_a
INT
Output signal
• 16384 ≡ 100 %
bActEqSet
INT
Active: Setpoint and actual value are identical, no system deviation available
