Analog functions:
An analog voltage (0 to + 10 V) can be taken from the control terminals (max. 5 mA). Various
functions are available, the following generally applies:
0 Volt analog voltage always corresponds to 0% of the selected value.
10 V always corresponds to the motor nominal value (unless otherwise stated) multiplied by the
P419 standardisation factor, e.g.
=>
100%

0 = No function,
no output signal at the terminals.
1 = Actual frequency,
the analog voltage is proportional to the FI output frequency.
2 = Actual speed
, this is the synchronous speed calculated by the FI based on the existing
setpoint. Load-dependent speed fluctuations are not taken into account.
3 = Current
, the effective value of the output current supplied by the FI.
4 = Torque current,
displays the motor load torque calculated by the FI. (100% = P112)
5 = Voltage
, the output voltage supplied by the FI.
6 = DC Link voltage,
the DC voltage in the FI. This is not based on the motor rated data. 10
Volt, standardised at 100%, is equivalent to 850 Volt DC (400V devices) or 450 Volt DC
(230V devices)!
P419 can be used for modification of the required working range. The maximum analog
output (10V) corresponds to the standardisation value of the appropriate selection.
7 = Value from P542 External control
, the analog output can be set using parameter P542
independently of the actual operating status of the FI to 0.0 ... 10.0V.
8 =
… 14 reserved
30 = Actual set frequency before ramp
, shows the frequency produced by any upstream
controllers (ISD, PID, etc.). This is then the set frequency for the power level adapted via
the acceleration or deceleration ramp (P102, P103).
31 = Value via BUS,
the analog output is controlled via a bus system. The process
data are directly transferred (P546, P547, P548).
