0 ... 2 The exact position of the rotor must be known in order to operate a PMSM. This can be
determined by various methods.
{ 6 }
0 = First enable
1 = Supply voltage
2 = DIN/BUS IO IN
NOTE:
Identification of the rotor position is only performed if the VFD is in the "ready to switch-on" state
and the rotor position is not known (see P434, P481 function 28).
Use of the parameter is only advisable if the test signal method is set (P330).

0 ... 3 Selection of the source for the control word (CTW) and the main setpoint (MSW) with active PLC
functionality (P350 = 1). With the settings "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
accepted if the variable frequency drive is in "ready for switch-on" status.
0 = CTW &MSW = PLC: The PLC supplies the control word (CTW) and the main setpoint

setpoint (MSW) corresponds to the setting in parameter (P510[-01]).
(MSW) corresponds to the setting in parameter (P509)/(P510[-01]).
Identification of the PMSM rotor position is performed when the
drive is enabled for the first time.
Identification of the PMSM rotor position is performed when the
supply voltage is applied for the first time.
Identification of the PMSM rotor position is triggered by an
external order by means of a binary bit (digital input (P420) or
Bus-in bit (480), setting "79", "Rotorpos. Ident.").
