6 Function & parameter description
Group 6 – PID setup
86 Lenze · Inverter i510 / i550 - Cabinet · Operation Manual · 0.4 EN · 02/2016
6.8.5 PID Influence
The Influence of the PID can be ramped up / down with a external Trigger.
Example usage: Winding application.
PID influence ramps active
1:Constant TRUE
(Reference see P400:1)
Activates PID influence ramp by external Trigger
States:
TRUE: Influence ramp time have no effect on PID
Transition states:
FALSE --> TRUE: Ramping up PID according P607:1
TRUE --> FALSE: Ramping down PID according P607:2
0.0 ... [5.0] ... 999.9 s
Ramp up time during switch ON of influencing (P400:48 PID influence
ramps active)
(Time from 0 to Maximum frequency)
0.0 ... [5.0] ... 999.9 s
Ramp down time during switch OFF of influencing (P400:48 PID influ-
ence ramps active)
(Time from Maximum frequency to 0)
6.8.6 PID Alarms
-300.00 ... [0.00] ... 300.00 PUnit
Minimum alarm of PID feedback signal
If PID feedback signal is lower than Min alarm level the signal is activat-
ed. Signal can be used to switch Digital Output / Relays / Network Out-
put (Selection 75-77)
-300.00 ... [100.00] ... 300.00 PUnit
Maximum alarm of PID feedback signal
If PID feedback signal is high than Min alarm level the signal is activated.
Signal can be used to switch Digital Output / Relays / Network Output
(Selection 75-77)
6.8.7 PID Sleep/Rinse function
The PID has an integrated sleep & rinse function.
Sleep function: Stop PID if there is no demand from the process
Rinse function: Start the inverter periodically during sleep mode to prevent accumulation of deposits in
the piping or the pump system.
