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.
0 = STW & HSW = PLC: The PLC supplies the control word (STW) and the main setpoint
1 = STW = P509: The PLC supplies the main setpoint (HSW), the control word (STW)
2 = HSW = P510[1]: The PLC supplies the control word (STW), the source for the main
3 = STW & HSW = P509/510: The source for the control word (STW) and the main setpoint

0 ... 3 This parameter can be used to determine how the control word (STW) for the master function and
the status word (ZSW) of the frequency inverter undergo further processing by the PLC.

0 = Off: The control word (STW) of the master function (P503≠0) and the status word (ZSW)
1 = STW for broadcast: The control word (STW) for the master value function (P503≠ 0) is set
2 = ZSW for bus: The status word (ZSW) of the frequency inverter is set by the PLC. In order

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".
to do this, the status word must be redefined in the PLC using process value
"28_PLC_status_word".
