82 BU 0800 en-4521
P351 PLC set val. select.
Setting range
0 … 3
Factory setting
{ 0 }
Description
Selection of the source for the control word (CTW) and the main setpoint (MSW) with
active PLC functionality P350 = {1}). With the settings P351 ={0} and {1} the main
setpoints are defined via P553, but the definition of the auxiliary setpoints remains
unchanged via P546. This parameter is only adopted if the frequency inverter is in
"Ready for switch-on" status.
Setting values
Value Meaning
0
STW & HSW = PLC
The PLC provides the control word (CTW) and the main setpoint
(MSW) Parameters P509 and P510 [-01] have no function.
1
CTW = P509
The PLC provides the main setpoint (MSW) The control word
source (CTW) corresponds to the setting in parameter P509.
2
MSW = P510[1]
The PLC provides the control word (CTW) The source for the main
setpoint (MSV) corresponds to the setting in parameter P510[-01].
3
CTW & MSW = P509/510
The source for the control word (CTW) and the main setpoint
(MSW) corresponds to the setting in parameter P509 / P510 [-01].
