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.

[ 100 ] Analog functions P418 (= 0 ... 14, 30, 31)
Using this parameter an adjustment can be made to the analog output for the selected operating
range. The maximum analog output (10V) corresponds to the standardisation value of the
appropriate selection.
If therefore, at a constant working point, this parameter is raised from 100% to 200%, the analog
output voltage is halved. 10 Volt output signal then corresponds to twice the nominal value.
For negative values the logic is reversed. A setpoint value of 0% will then produce 10V at the
output and -100% will produce 0V.
Digital functions P418 (= 15 ... 28, 34...52)
The switching threshold can be set using this parameter for the functions Current limit (= 17),
Torque current limit (= 18) and Frequency limit (= 19). A value of 100% refers to the corresponding
motor nominal value (see also P435).
With a negative value, the output function is output negated (0/1
→ 1/0).
