[ 0 ]
0 = Actual frequency [Hz], i.e. the output frequency currently being supplied by the FI
1 = Speed [1/min], i.e. the actual speed as computed by the FI
2 = Nominal frequency [Hz], i.e. the output frequency which has been defined as the active set-
point frequency. Obviously the current output frequency may deviate from the setpoint.
3 = Current [A], i.e. the instantaneous output current measured by the FI
4 = Torque current [A], i.e. the FI output current producing the torque
5 = Voltage [Vac], i.e. the current alternating voltage the FI is supplying at its output
6 = D.c. link voltage [Vdc], i.e. the internal direct voltage of the FI which depends on among
other factors the amount of the mains voltage.
7 = Cos , i.e. the calculated value of the current power factor
8 = Apparent power [kVA], i.e. the current apparent power calculated by the FI
9 = Effective power [kW], i.e. the current effective power calculated by the FI
10 = Torque [%], i.e. the current torque calculated by the inverter
11 = Field [%], i.e. the current strength of the field in the motor calculated by the FI
12 = On-time, time during which voltage has been applied to the FI
13 = Run-time, time for which the FI has been enabled
14 = Analog input 1 [%] *, value currently applied to analogue input 1 of the FI
15 = Analog input 2 [%] *, value currently applied to analogue input 2 of the FI
16 = Position setpoint **, desired position to be implemented by the control system
17 = Position current val **, current position of the driven unit
*) not appropriate unless the custom interface features the inputs required
**) only with PosiCon special extension

The operational factor selected in parameter P001 >Selection of operational value to be displayed< is
scaled in accordance with the scaling factor and displayed in P000. This is a way to indicate operation
values typical of the plant involved, e.g. bottles/hour.
