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. A
negation of the function can be set in the parameter >Norm. analog output< P419.

[ 100 ] Analog functions P418 (= 0 ... 14, 30, 31)
Using this parameter an adjustment can be made to the analog output for the selected working
range. The maximum analog output (10V) corresponds to the standardisation value of the
corresponding 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. A setpoint value of 0% will then produce 10V at the output
and 100% will produce 0V.
Digital functions P418 (= 15 ... 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).
