P351 PLC setpoint selection
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 taken over if the frequency inverter is in
"Ready to start" status.
Setting values
Value Meaning
0 STW & HSW = PLC
The PLC supplies the control word (CTW) and the main setpoint
(MSW), and parameters P509 and P510[-01] have no effect.
1 CTW = P509
The PLC supplies the main setpoint (MSW), the control word
(CTW) corresponds to the setting in parameter P509
2 MSW = P510[1]
The PLC supplies the control word (CTW), the source for the main
setpoint (MSW) 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].
P353 Bus status via PLC
Setting range
0 … 3
Factory setting { 0 }
Description
This parameter decides whether the control word for the master function and the
status word of the frequency inverter are further processed by the PLC.
Setting values
Value Meaning
0 Off
Control word for the master function and the status word continue
to be processed by the PLC.
1 CTW for broadcast:
The control word for the master value function P503≠ 0 is set by
the PLC. In order to do this, the control word must be redefined in
the PLC using process value "34_PLC_Busmaster_Control_word".
2 Status word (STW) for the bus
The status word of the frequency inverter is set by the PLC. In
order to do this, the status word must be redefined in the PLC
using process value "28_PLC_status_word".
