Parameter Setting value / Description / Note Comments
P509
Interface
(interface)
SK 300E, SK 700E, SK 750E
0 ... 21
{ 0 }
Selection of the interface from which the inverter is controlled.
0 = Control terminal or keyboard control with the Control Box (option) ,the ParameterBox
(option) or the Potentiometer option
1 = Control terminals only, the inverter can only be controlled via the 4 digital inputs and the
analog input.
2 = USS setpoint, the frequency setpoint is transferred via the USS protocol. Control via the
digital inputs is still active.
3 = USS control word, the control signals (enable, direction of rotation, ...) are transferred via
USS, the setpoint via the analog input or the fixed frequencies.
4 = USS, all control data is transferred via the USS protocol. The analog input and the digital
inputs have no function (except safety functions, see below)
5 = …
P509
Control word source
(Control word source)
SK 5xxE
0 ... 10
{ 0 }
Selection of the interface via which the FI is controlled.
0 = Control terminal or keyboard control with the Control Box (if P510=0), the
ParameterBox (not extension parameter box) or via BUS I/O Bits.
1 = Only control terminals , the FI can only be controlled via the digital and analog inputs or
via the bus I/O Bits.
2 = USS control word: the control signals (enable, direction of rotation, ...) are transferred via
the RS485 interface. The setpoint is transferred via the analog input or the fixed
frequencies.
Above SK 540E this setting should also be selected if communication via Modbus RTU is
intended. The frequency inverter automatically detects whether this is a USS protocol or a
Modbus protocol.
3 = …
P510
Aux. setpoint interface
(Auxiliary setpoints interface)
SK 700E, SK 750E
0 ... 8
{ 0 }
Selection of the interface from which the inverter is controlled.
0 = Auto: The auxiliary setpoint value is automatically
taken from the interface of the main setpoint value

1 = USS
2 = CANbus
3 = Profibus

Setpoints source
(Setpoints source)
SK 5xxE
0 ... 10
{ 0 }
Selection of the setpoint source to be parameterised.
[-01] = Main setpoint source [-02] = Auxiliary setpoint source
Selection of the interface via which the FI receives the setpoint.
0 = Auto: the source of the auxiliary
setpoint is automatically derived from
the setting in the parameter P509

inputs control the frequency, including
