All of the relay functions described in parameter P434 >Function relay 1< can be transmitted via the
analogue output as well. Whenever a condition is true, a voltage of 10.0V will be applied to the out-
put terminals. A negation of the function can be defined in parameter P419 >Scaling the analogue
output<.

Analog functions P418 (= 0 ... 14, 30, 31)
This parameter can be used to adjust the analogue output to the desired working range. The maxi-
mum analogue output (10V) will correspond to the scaled value of the option selected.
Consequently if the setting of this parameter is increased from 100% to 200% while the operating
point remains the same, the analogue output voltage is reduced by half. Accordingly a 10-volt output
signal will correspond to twice the nominal value.
Where negative values are concerned the logic is reversed. In that case a setpoint of 0% will be put
out as 10 volts at the output and a 100% setpoint as 0 volt.
Digital functions P418 (= 15 … 52)
This parameter can be used to set the switching threshold for the functions current limit (= 17),
torque current limit (= 18) and frequency limit (= 19). A 100% setting will be equivalent to the respec-
tive nominal value of the motor (see also P435).
If a negative value is selected the function assigned to the analogue output is put out as a negated
value (0/1 1/0).
