List of possible digital functions of the analog outputs
All relay functions described in parameter P434 can also be transferred via the analog output. If a
condition has been fulfilled, then there will be 10 V at the output terminals. Negation of the function
can be specified in parameter P419.

Analog functions P418 (= 0 ... 6 and 8 … 14, 30)
With this parameter an adjustment can be made to the analog output for the selected working
range. The maximum analog output (10 V) corresponds to the scaling value of the appropriate
selection.
Therefore, if this parameter is raised from 100 % to 200 % at a constant working point, the analog
output voltage is halved. The 10 Volt output signal then corresponds to twice the nominal value.
For negative values the logic is reversed. An actual value of 0 % will then produce 10 V at the
output and -100 % will produce 0 V.
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).
