The frequency setpoint at connector XFS corresponds to the frequency of the
voltage vector at output connector SWG.FU . The absolute value of the voltage
vector setpoint at connector XBU corresponds to the absolute value of the voltage
vector at output connector SWG.BU. It is not possible to enter a current setpoint.
The closed-loop current control and therefore connectors SWG.KP and SWG.TN
are not active (the frequency setpoint XFS refers to the value FME entered at SWG
as well as at the MSZ block. Both connectors should have the same values.)
SWG.IFM = 1
The frequency setpoint at connector XFS corresponds to the frequency of the
voltage vector at output connector SWG.FU. The absolute value of the voltage
vector at output connector SWG.BU is changed proportional to this. It is not
possible to enter a setpoint at connector XBU and a current setpoint. The closed-
loop current control and therefore connectors SWG.KP and SWG.TN are not
active.
SWG.IRM = 1
The frequency setpoint at connector XFS corresponds to the frequency of the
voltage vector at output connector SWG.FU. The absolute value of the voltage
vector at the output connector BU is closed-loop controlled. The setpoint input at
connector XBU is not active. It is possible to enter a current setpoint at connector
SWG.XBI. The entered current setpoints refer to nominal shunt data. The controller
parameters SWG.KP and SWG.TN are active.
If the drive converter is shutdown with a fault during setpoint generator operation, a
sequence must be maintained to re-enable the setpoint generator.
Acknowledge fault - cancel mode - enable inverter - inhibit inverter
SWG operation is now possible by re-selecting the mode and then enabling the
inverter.
