Selection of the interface used to control the inverter (take the P503 pilot function output into ac-
count, if applicable)
0 =
Control terminals or keyboard control **/***
using either the ControlBox
(option), the Potentiometer Box (option) or via bus I/O bits (option).
1 =
Control terminals exclusively */***,
the FI will be controlled via the digital and analogue
inputs only (a customer interface will be required!) or via bus I/O bits (option).
2 =
USS setpoint */***,
the frequency setpoint is transmitted via the RS485 interface. The op-
tion of digital input control is still available to the operator however.
3 =
USS control word *,
whereas the control signals (enable, phase sequence, ...) are trans-
mitted via the RS485 interface, the setpoint is applied to the analogue input or transmitted
as a fixed frequency.
4 =
USS *,
all of the control information is transmitted via the RS 485 interface. No function is
assigned to either the analogue input or the digital inputs through. This setting is required
when the external ParameterBox / p-box is used!

Keyboard control
(ControlBox, PotentiometerBox) is disabled whereas parameter setting contin-
ues to be available.
**)
If during keyboard control communication does not proceed correctly (time-out for over 0.5 secs),
the inverter locks up without generating an error message.
