P418 Function analog output

Analog functions:
An analog (0 … +10 volt) voltage can be picked off at the control terminals (max. 5 mA).
Different functions are available, and the following generally applies: 0 volt analog voltage
always correspond to 0% of the selected value. 10 volt corresponds to the respective
nominal motor value (unless specified differently), multiplied by the factor of the scaling
P419, e.g.:

0 = no function, no output signal at the terminals.
1 = actual frequency, the analog voltage is proportional to the FC output frequency.
2 = Actual speed; this is the synchronous speed determined by the FC, based on the
applied setpoint value. Load-dependent speed fluctuations are disregarded.
3 = Current; this is the effective value of the output current supplied by the FC.
4 = Torque current; this indicates the motor load torque calculated by the FC.
(100% = P112)
5 = Voltage; this is the output voltage supplied by the FC.
6 = DC bus voltage; this is the DC voltage in the FC. This is not based on the
nominal motor data. 10V with scaling of 100% corresponds to 450V DC (230V) or
850 volt DC (480V)!
7 = Value of P542 ; the analog output can be set via parameter P542 independent of
the current operating state of the FC. For example with bus addressing (parameter
order), this function can supply an analog value from the control.
8 = Apparent power ; this is the current apparent motor power.
9 = Active power ; this is the current active power calculated by the FC.
10 = Torque [%] ; this is the current torque calculated by the FC.
11 = Field [%] ; this is the current field in the motor calculated by the FC.
12 = Output frequency ± ; the analog voltage is proportional to the output frequency
of the FC, zero being shifted to 5V. With rotation direction right, the values 5V to
10V are output, and with rotation direction left, values 5V to 0V.
13 = Actual speed ±; this is the synchronous speed determined by the FC, based on
the applied setpoint value. With rotation direction right, the values 5V to 10V are
output, and with rotation direction left, values 5V to 0V.
14 = Torque [%] ± ; the current torque calculated by the FC, zero being shifted to 5V.
With motor-driven torques, values from 5V to 10V are output, and with
regenerative torques, values from 5V to 0V.
30 = Setpoint frequencies of frequency ramp; this indicates the frequency
resulting from any upstream controllers (ISD, PID, …). Then, this is the setpoint
frequency for the rating class after it has been adjusted via the run-up or the
brake ramp (P102, P103).
31 = Value via BUS; the analog output is controlled via a bus system. The process
data are transmitted directly (P546, P547, P548).

Digital functions:
All relay functions described in parameter >Function relay 1< P434 can also be transmitted
via the analog output. If a condition is met, 10V will be applied at the output terminals. A
negation of this function can be specified in parameter >Scaling of analog output< P419.
