The following modes are available for the analog outputs.
In voltage mode the output range is -10V to 10V. If the scaling parameter is 1.000 then -10V and 10V are produced when the source parameter is at -
maximum and maximum respectively. Different scaling can be applied with Pr 7.23. If the result of the scaling produces an output of more than +/-
100% the output is clamped within the +/-10V range.
In current modes with a scaling parameter of 1.000 the minimum and maximum current are produced when the source parameter is at 0 and
maximum respectively. Therefore in 4 - 20mA mode the output is 4mA when the source parameter is zero. Different scaling can be applied with
Pr 7.23. If the result of the scaling produces an output of more than 100% the output is clamped at 20mA.
If high speed update mode is selected and the source for the output is one of the parameters designated for high speed analog output operation (see
start of this section) the output is updated at a higher rate with special scaling. If the parameter selected is not designated for this mode the output is
updated at the normal rate. If speed feedback or power is selected for high speed mode for both analog output 1 and analog output 2 the setting is
ignored for analog output 2. If the high speed mode is selected the output is always a voltage signal.
