Analog functions
An analog voltage (0 to + 10 V) can be taken from the control terminals (max. 5 mA). Various functions
are available, whereby:
0 Volt analog voltage always corresponds to 0% of the selected value. 10 Volt corresponds to the
current motor nominal value multiplied by the standardisation factor P419, like e.g.:

100%

0 = No function, no output signal at terminals.
1 = Actual frequency, the analog voltage is proportional to the frequency at the FI output.
2 = Speed, this is the synchronous speed calculated by the FI based on the existing setpoint. Load-
dependent speed fluctuations are not taken into account.
If Servo mode is being used (P300), the measured speed will be output via this function.
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.
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!
7 = Value of P542, the analog output can be set using parameter P542 independently of the actual
operating status of the FI. During Bus control this function can supply such things as an analog
value from the control.
8 = Apparent power: the actual apparent power calculated by the FI.
9 = Effective power: the actual effective power calculated by the FI.
10 = Torque [%]: the actual torque calculated by the FI.
11 = Field [%]: the actual field in the motor calculated by the FI.
12 = Current frequency +/-, the analog voltage is proportional to the output frequency of the FI,
whereby the zero point is shifted to 5V. For rotation to the right, values between 5V and 10V are
output, and for rotation to the left values between 5V and 0V.
13 = Speed +/-, is the synchronic rotation speed calculated by the FI, based on the current setpoint,
whereby the zero point has been shifted to 5V. For rotation to the right, values between 5V and
10V are output, and for rotation to the left values between 5V and 0V.
If Servo mode is being used, the measured speed will be output via this function.
14 = Torque [%]+/-, is the actual torque calculated by the FI, whereby the zero point is shifted to 5V.
For drive torques, values between 5V and 10V are output, and for generator torque, values
between 5V and 0V.
30 = Setpoint frequency before ramp, displays the frequency produced by any upstream controllers
(ISD, PID, etc.). This is then the setpoint frequency for the power stage after it has been adjusted
by the start-up or braking ramp (P102, P103).
Digital functions: All relay functions described in Parameter >Function Relay 1< P434 can also be
transferred via the analog output. If a condition has been fulfilled, then there will be 10V at the output
terminals. Negation of the function can be set in parameter >Analog output standardisation< P419.
